Poměr benzínu k oleji pro řetězovou pilu Husqvarna
Každé motory a základní karburátory společnosti s řetězovou pilou pracují s jiným množstvím maziva. Proto se podíl oleje a benzínu pro řetězovou pilu může mírně lišit.
Nejčastěji při míchání paliva s olejem výrobci doporučují používání proporcí 1:50 nebo 1:40. To znamená, že 1 část maziva motoru musí být smíchána v 50 nebo 40 částech paliva.
Je docela snadné převést poměr do přístupnější formulace. Například 1 litr paliva obsahuje 1000 ml. Pokud je 1000 ml rozděleno 40, dostanete 25 ml. To znamená, že 25 ml maziva bude nutné zředit 1 litr benzínu. Stejný vzorec by měl být použit, když výrobce doporučuje připravit směs paliva výhradně v poměru 1:50. K tomu musí být 1000 ml rozděleno 50, což má za následek 20 ml. To znamená, že 20 ml maziva motoru by mělo být zředěno v jednom litru paliva.
Věci se s čínskými řetězovými pilami trochu liší. Jejich výrobci doporučují zředit benzín pro řetězovou pilu v poměru 1:25. To znamená, že majitelé čínských nástrojů musí promíchat přesně 40 ml maziva v 1 litru čistého benzínu. Tento poměr je způsoben skutečností, že pokud jde o kvalitu shromáždění a výběr komponent, jsou tyto řetězové pily o něco nižší než jejich západní protějšky. V motorech amerických, evropských a japonských modelů je vzdálenost mezi válci a písty mnohem menší než vzdálenost řetězových pilovačů z Číny. V tomto ohledu je množství maziva potřebného k provozu bývalého. daleko méně.
Jaký benzín se vylévat do řetězové pily
Pojďme zjistit, jaký druh paliva se doporučuje pro tento typ zařízení. Protože na řetězových pilách je motor 2T (dvoumok) a na něm nelze nainstalovat olejové čerpadlo, je zakázáno používat pro pilu čistý benzín používat čistý benzín. Do pily se nalije palivová směs paliva a oleje. Normy pro doplňování motorových pilovačů různých modelů jsou výrobcem regulovány.
Zvažte, jaký druh benzínu nalít do odborníků na řetězovou pilu. Pomocí řetězové pily se provádí s palivem s oktanovým počtem více než 92. Chcete.li vytvořit směs, nesmíte používat palivo s platností, vyrobené z kondenzátu, který zahrnuje vodu a různé nečistoty.
Domácí pily běží na palivo Ai-80. Pro zahraniční úpravy je potřeba benzín AI-92. Často se stává, že pokyny označují stupeň paliva Ai-95. Odborníci se však domnívají, že benzín Ai-95, který se vyrábí v Ruské federaci, nesplňuje standard kvality. Toto palivo obsahuje mnoho antiknokových přísad.
Při vytváření směsi je možné použít takový benzín pro řetězovou pilu pouze s vysokou kvalitou. Složitost aplikace spočívá v používání aditiv, přičemž pomocí výrobců zvyšuje výkonnostní vlastnosti paliva, které má nižší oktanové číslo. Proto se nedoporučuje vyplnit 95 benzín.
Jak zředit benzín olejem řetězové pily?
Směs benzínu a oleje musí být neustále připravena v čisté nádobě, na nichž jsou měřící značky. To poskytne majiteli řetězové pily schopnost přesně určit množství benzínového a motorového oleje, které mísí. Materiál, ze kterého je kontejner vyroben, musí být odolný vůči účinkům benzínu. Kovové nádoby jsou pro to velmi vhodné.
Nalijte palivo a mazivo skrz zavlažovací plechovku, abyste zabránili ztrátě komponent. Aby se ojeté mazivo v palivu zcela rozpustily, bude nutné je vyplněný nádoba několikrát otřesen. Výsledkem je, že by benzínová směs měla být rovnoměrně zbarvena. V tomto případě se musíte ujistit, že ve spodní části lodi není žádné srážení.
Jaké palivo použití pro řetězovou pilu?
Výběr správného paliva je důležitým a významným problémem. Jediným správným přístupem k jeho řešení je pečlivá studie uživatelské příručky, která označuje typ a značku paliva, proporce míchání benzínu a oleje a také odráží všechny funkce tohoto nástroje. Moderní standardy vyžadují použití vysoce oktanových rafinovaných paliv a speciálních typů motorového oleje.
Olej pro dvoutaktní motory řetězových pila
Moderní benzínové pily mohou být vybaveny motory s 2 signály nebo čtyřtak. V posledně jmenovaném je olej původně dodáván do částí skupiny tyče připojujících kliky přímo z klikové skříně motoru.
Na rozdíl od nich, ve dvoudobých továrních motorech, palivo vstupuje do letadla umístěného pod pístem. K doplnění takové řetězové pily musí být do čerstvého benzínu přidán motorový olej. Mazá otřesné části motoru a zabrání jejich předčasnému opotřebení.
Olej pro motory s řetězovou pilou s 2 sid musí dodržovat řadu důležitých parametrů:
- Při hoření oleje by mělo být vytvořeno minimální množství popela. Nejlepší je, že použitý olej je vyhořen v plném rozsahu;
- Mazivo se musí rychle rozpustit v benzínu;
- Olej pro dvoutaktní motory musí být bez škodlivých nečistot, které mohou vést k zablokování v karburátorových liniích.
Výběr olejů pro dvoutidelné motory do značné míry závisí na typech chladicích systémů. Pro mazání motorů s vnitřním spalováním vybaveným systémy chlazení vzduchu jsou vhodné 2t standardní formulace. U motorů chlazených kapalnými systémy vyberte oleje označené TC-W3.
V každém případě musí být olej pro trvalé mazání motoru použitého nástroje v nejvyšší možné kvalitě. Během spalování tvoří oleje s nízkou kvalitou velkého množství uhlíkových ložisek, které se usazují na stěnách válce a pod pístovými prsteny motoru s vnitřním spalováním. Z tohoto důvodu standardní prsteny ztratí schopnost komprimovat, v důsledku toho, které otřepy se objevují na vnitřních stěnách motorového válce. Kromě toho maziva s nekvalitním vedením vede k přehřátí částí klikového mechanismu. Výsledkem je, že se úplně zaseknou a selhávají.
Co použít olej z motorové pily?
Chcete.li přesně zjistit, který olej použít k namazání řetězce řetězové pily, budete muset prostudovat pokyny výrobce. Téměř všichni výrobci nástrojů doporučují vylévat produkt, který vyniká s nejvyššími adhezními vlastnostmi. To znamená, že materiál použitý k mazání řetězce musí dodržovat kovové povrchy řetězce a tyčinky.
Musíte zjistit, proč má mazivo lepidlo. Během pohybu řetězce na standardní liště dosáhne pilovací prvek vysokou rychlost. Pokud pro mazání používáte řetězový olej z řetězu s nízkou adhezivní pilou, více než polovina kapaliny odletá z horní části pneumatiky setrvačností, nikdy nedosáhne dna. Výsledkem je, že se takový olej ukáže jako neúčinný a pneumatika spolu s řetězem rychle selže kvůli neustálému tření.
Poměr benzínu k oleji
Standardní poměr oleje k benzínu, který je relevantní pro většinu řetězových pilovačů, je 1 až 50. To znamená, že k 1 litru benzínu musí být přidáno 20 ml oleje. Každý výrobce však má své vlastní požadavky na složení palivové směsi, které jsou způsobeny návrhem motoru, zvláštností jeho parametrů a dalších faktorů. Je nemožné určit, jaké proporce jsou nejvhodnější pro daný nástroj.
Úplné a přesné informace lze získat pouze z uživatelské příručky. Pokud neobsahuje žádné pokyny týkající se složení směsi paliva, pak by se obecně uznávaná praxe měla být dodržena a učinit ji v poměru 1: 50. Existují i jiné možnosti, od 1: 20 do 1: 50.
Obrázek 3. Poměr oleje a benzínu pro směs paliva
Je možné nalít 95 benzín do řetězové pily?
Téměř v každé provozní příručce najdete pokyny od výrobců, které pro pravidelné doplňování nástrojů pro domácnost potřebujete používat benzín s konstantním oktanovým počtem ne vyšších než 92. Navzdory tomu mnoho začínajících zahradníků nadále doplňuje své pily s 95. benzínem, marně věří, že je lepší.
Je třeba si uvědomit, že motory všech dovážených a některé domácí nástroje byly původně navrženy tak, aby fungovaly na 92. benzínu. Pokud se do palivové nádrže nástroje nalije 92 benzín, povede to k tlaku pístu do opačného směru, který se často nazývá detonace. Tento nebezpečný proces se stane cyklickým a bude se opakovat s každou revolucí klikového hřídele motoru. Pravděpodobně není třeba říkat, že použití 98. benzínu bude ještě horší ovlivnit provoz pístu a stav motoru řetězové pily.
Palivová směs: podíl oleje a benzínu pro řetězovou pilu
Motor řetězové pily je srdcem nástroje, takže je velmi důležité používat správně připravenou palivovou směs.
Palivová směs pro řetězovou pilu je připravena ze dvou složek. Olej a benzín. Řetězové pily jsou vybaveny dvoutaktními motory, takže do mazacího systému není přidán olej (jako u čtyřtaktního motoru), ale přímo do benzínu. Zároveň je velmi důležité pozorovat správné proporce ingrediencí, samozřejmě, v žádném případě se nepokouší pracovat na čistém benzínu, protože tímto způsobem velmi rychle „zabijete“ řetězovou pilu.
Pokud mluvíme o tom, jaký druh benzínu se nalévat do řetězové pily, pak bude optimální používat palivo s oktanovým hodnocením A-95, v tomto případě se mohou úspory paliva ukázat jako žalostné. Evropští výrobci často naznačují, že je možné používat benzín A-90 nebo A-92, ale v postsovětských zemích je kvalita benzínu nižší než kvalita Evropy, takže v naší realitě je lepší použít kvalitnější benzín.
Pokud jde o podíl samotné směsi benzínového oleje, je zde vše jednoduché: musíte postupovat podle pokynů pro nástroj. Všichni výrobci řetězových pilovačů označují požadovaný poměr v příručce pro pokyny nebo v pasu nástroje, kromě toho se proporce pro doplňování motorové pily liší v závislosti na modelu řetězové pily. Poměr oleje a benzínu k řetězové pile slavných výrobců je zpravidla poměrem 1:40 nebo 1:50, což znamená 1 část oleje, což znamená například 40 částí benzínu. Nyní aritmetika 1 litr benzínu = 1000 ml benzínu, rozdělení 40 a dostáváme 25 ml oleje. Pokud budete postupovat podle stejných kroků k poměru 1:50, dostanete 20 ml oleje na 1 litr benzínu. Pokud jde o rozpočtové řetězové pily vyrobené v Číně, situace je mírně odlišná. Poměr benzínového oleje k řetězové pile vyrobeno v Číně 1:25, to znamená, rozdělte 1000 ml benzínu o 25, dostaneme 40 ml oleje. Jde o to, že ve značkových řetězových pilách je pevná sestava a vzdálenost mezi písty a válci v motoru mnohem menší než u čínských řetězových pilach, proto se požadované množství oleje liší téměř dvakrát.
K měření správného množství oleje použijte konvenční lékařskou stříkačku s dostatečným objemem.
Another subtlety. first fill the dry gasoline can with gasoline and then oil. The procedure, on the contrary, is fraught with a poor quality fuel mixture, because the oil is denser, it will stick to the bottom of the canister. what a good mixing here.
Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of your chainsaw!
If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared combustible mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats up” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.
At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation.
Unsuitable fuel mixture must be disposed of.
Small private companies from China and other Asian countries specialize in the production of motor oils, which are sold at a lower cost in the markets under the trademarks of leading manufacturers.
- The characteristics of counterfeit products are an order of magnitude lower than those of the branded originals. The constant use of counterfeit products adversely affects the operation of the chainsaw and the durability of its operation.
- Only an experienced specialist can determine the status and quality of oil, therefore, you can avoid possible risks by buying consumable components in a network of branded and licensed retail outlets.
- The use of substandard lubricants for service specialists is a legal basis for depriving the owner of a faulty saw of warranty repair and restoration obligations.
It is better to prepare the mixture in an amount that should be enough for one-time work. The problem lies in the irreversible deterioration of the working properties of the mixture during storage. The finished composition is recommended to be used over the next few days.
A mixture of gasoline with a month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.
- With minimal damage to quality, it is advisable to store gasoline with oil for no more than 2 weeks. At an ambient temperature of 25 degrees Celsius or more, this period is reduced to 8-10 days.
- In order to save money, the expired mixture can be gradually consumed by mixing it into the fresh composition in an amount of no more than 10% of the total volume.
In order to avoid problems associated with the failure of the fuel system, it is recommended to filter the prepared mixture through a non-fiber material such as suede, or a fine-mesh twill weave, a metal mesh.
Benefits of branded oils
Many domestic and foreign manufacturers specialize in the production of special motor oils, but the highest rating indicators are for branded products from STIHL, Husqvarna and Makita.
Only in certain parameters are the domestic motor oils of the Lukoil trademark inferior to the branded assortment.
The list of advantages of branded engine oils includes:
- economical consumption;
- stability of performance under difficult operating conditions and during long-term storage;
- minimum amount of toxic compounds in exhaust gases;
- almost complete absence of carbon deposits.
According to the American classification, API-TB oils can be used for work in household and professional models. The Japanese counterpart is JASO-FB and JASO FD. Preparation of a combustible mixture using oil for 4-stroke engines is strictly excluded.
Red, green or any other color of oil determines the product belonging to the assortment of a certain manufacturer, therefore, when determining the characteristics of the material, it is not taken into account. Be extremely careful when choosing a motor oil of unknown composition and origin.
Husqvarna chainsaw Combi Oil and Fuel Can review
Until you receive additional information about the quality and operational parameters, it is better to temporarily refuse to use such material.
It is allowed to mix motor oils of the same type in composition and purpose, produced by brands known for the quality of their assortment. Under no circumstances is it allowed to mix mineral and synthetic oils.
The ratio of gasoline to chainsaw oil
Household and professional chainsaws are powered by two-stroke internal combustion engines operating on a metered mixture of gasoline and engine oil adapted to the difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw is one of the important conditions for stable traction characteristics of the engine and low-cost development of its assigned resource.
The need to obtain a sufficiently high power from a small-cube power unit makes it necessary to operate chainsaw engines at high-speed modes, therefore, increased requirements are imposed on the quality of both components of the fuel mixture.
The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, which have water and mechanical impurities in their volume, are not suitable for the preparation of fuel.
- The opinions of experts on the use of gasoline of different brands are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
- On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw only with full confidence in its quality.
- The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index.
Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.
Stricter criteria for the selection of the oil component. In the best variant, it is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for operation in high-speed two-stroke air-cooled internal combustion engines.
The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic counterparts are distinguished by improved performance and compliance with environmental standards.
- maintain working properties in a wide range of operating temperatures;
- do not form carbon deposits;
- contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.
Working proportions of the fuel mixture
The standard gasoline to oil mixture ratio for carburetor chainsaw engines of various models is 40: 1 and 50: 1. This proportion provides full lubrication of the rubbing parts of the crank mechanism and piston group, and also does not prevent the complete combustion of the gasoline-air mixture.
Taking into account external factors, the fuel mixture can be adjusted in the direction of increasing the amount of oil. Such a need arises at the stage of running in a new tool, as well as at high air temperatures. In this case, the standard oil dosage is increased by 20%.
In practice, an increase in the percentage of oil in the fuel mixture is used if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each case is determined by the sawman himself.
A large assortment allows you to choose oil that fully corresponds to the class and characteristics of the chainsaw, the conditions of its subsequent operation.
- For budget models, you can use oils of the Standard category, for professional chainsaws, consumable lubricants of the Super and Ultra categories are recommended.
- To prepare a full-fledged fuel mixture for a chainsaw, it is advisable to use branded oils or their branded counterparts recommended by the operating instructions. In particular, STIHL and Husqvarna engine oils of the same composition and application are completely interchangeable.
Experts recommend that owners of chainsaws exclude from the scope of attention motor oils intended for two-stroke engines of mopeds, boat motors and other mechanized household appliances.
The power units of this equipment operate in more comfortable conditions, which makes the requirements for their operational characteristics less stringent.
How to dilute for a Husqvarna saw
The manufacturer recommends the use of a special oil for Husqvarna in the operating instructions. It is adapted to the engines of this manufacturer, ensures a long service life and high-quality performance. Filled in a ratio of 1:50.
It is strongly not recommended to add oil for water-cooled two-stroke engines, for example, for outboard motors.
It is allowed to use oils for two-stroke air-cooled internal combustion engines from other manufacturers. If the proportion is not indicated on the canister, the chainsaw manufacturer Husqvarna recommends filling in an increased dose, in a proportion of 1:33.
Thus, 1 liter of gasoline for a Husqvarna chainsaw is filled with:
- 20 ml (colloquially grams) Husqvarna oil (1:50).
- 20 ml of other acceptable oil if the canister says 1:50.
- 30 ml for 1 liter of gasoline, 1:33, unless otherwise indicated.
Husqvarna does not recommend storing the prepared mixture for longer than 30 days. Before pouring, the settled mixture must be shaken.
How to thin for STIHL, in particular for the MS 180
The manufacturer recommends for the engines of its chainsaws, including the STIHL 180 MC model, HP Ultra oil in a ratio of 1:50. It provides the highest power, service life and cleanliness of the internal combustion engine. It is also recommended to use engine oils in STIHL labeled containers. It is important here to purchase original, but not counterfeit products.
How To Use 2 Stroke Oil to Fuel and Lubricate Gasoline Powered Chainsaws | Husqvarna
A mixture of gasoline with some oils is considered perishable, it is recommended to use it no later than 10-30 days after preparation.
In the case of a mix of oil and gasoline recommended by Calm, this is not the case. The mixture can be stored for up to 2 years. After long-term storage, the container must be shaken to mix possible sediment.
Motomix. STIHL ready-mixed fuel mixture, very convenient when there is no time or opportunity to mix fluids on site
For all chainsaws, unleaded gasoline with an octane rating of at least 90 is used. That is, AI-92, AI-95, AI-98. over, the most common and suitable option is AI-92. Gasoline with octane numbers 95 and 98 is recommended in cases where the engine runs mainly at high revs. We also recommend reading in more detail about the choice of gasoline.
An example of preparing 1 liter of a mixture in a ratio of 1:50.
- The capacity is approximately half (0.4-0.6 l) filled with gasoline.
- Pour 20 ml of oil into a clean liter container.
- Close the lid, shake the fuel until it becomes uniform in color.
- Gasoline is added to a liter, the lid is screwed on, the container is turned over several times.
Gasoline already diluted with oil mixes very easily with refilled clean gasoline, therefore, it is not necessary to mix strongly again.
The oils are painted in different colors, red or green. Therefore, by the uniformity of the color of the mixture or clots of different colors, you can clearly see whether the oil has stirred or not.
When oil overflows, the engine emits smoke. But smoke immediately after a cold start is in most cases typical for cold engine operation. After a few minutes of operation and warming up of the combustion chamber, the smoke disappears.
Refueling during running-in
When running in, all rotating and mating assemblies and engine parts are rubbed in. In some places, increased friction is possible, which can be stopped by additional lubrication.
In the operating instructions of most models and brands, there is no specific indication of the amount of oil for the break-in period. But many experts, with many years of experience, recommend pouring 20% more during running-in.
For example, if a ratio of 1:50 (20 ml per 1 liter) is indicated for a specific chainsaw, then another 20% should be added, that is, a fifth. 4 ml. As a result, pour 24 ml per liter.
The break-in period is approximately 10 engine hours. During this time, a small excess of oil will not do any harm. However, the running-in will take place in a more gentle mode, which in the future can increase the engine resource.
How to dilute gasoline with Huter saw oil
The manufacturer Huter does not allocate any one brand of oils for its chainsaws. There are recommendations for the general type. oils of the JASO FC classification or others: API TV, API ТС, JASO FB for two-stroke air-cooled internal combustion engines.
If the oil does not meet these standards, then problems and engine breakdowns may occur due to poor-quality lubrication.
In the instructions for use, Huter does not himself name the proportions, but indicates that the mixture is formulated in the proportion indicated by the oil manufacturer.
For example, if the canister reads 1:50, 20 ml is poured per 1 liter of gasoline. If 1:40 is specified. 25 ml per 1 liter.
The ratio of oil and gasoline for chainsaws of famous brands, the correct proportions, and also what should not be diluted
The preparation of the fuel mixture is a very important process, both the consumption of gasoline and the service life of the chainsaw depend on the observance of the correct proportions of gasoline and oil. Many are accustomed to stirring 1:50, but this is not correct, because the ratio of these two components is different for all manufacturers. Within the framework of the article, we will figure out what the most famous manufacturers recommend to fill in, in what proportions, and also give an example of how to dilute and prepare fuel correctly.
Can I mix oils of different colors and brands??
It is not recommended to mix oils of different brands. First, they can be performed on a different, incompatible basis. synthetics, semi-synthetics, mineral. Secondly, different brand oils may contain different additives. How they can chemically react with each other and what is formed as a result, it is impossible to predict.
The main thing is that there is simply no need to do this. It is more rational to add the rest of one brand of oil to gasoline and work out a mixture. And then start using another oil.
Pay attention to the labels, these are 3 different oils from STIHL, all differ, both in characteristics and in color. They cannot be mixed with each other, as the manufacturer himself writes about in his instructions.
How To Mix Fuel For a Chainsaw – Quick and Easy
Chainsaws need fuel to run. Without fuel, our chainsaws are just useless pieces of metal and plastic. Chainsaws (not including electric or battery units – which are actually a thing now) are powered by a 2 stroke engine that requires fuel mixed with a proper ratio of oil. If straight gasoline is run in a chainsaw it will likely result in catastrophic engine failure. Do not make this mistake. Make sure to mix your oil properly so that your chainsaw functions properly for years to come.
Mixing fuel for a chainsaw is done by combining the appropriate amount of 2-Cycle oil and Gasoline together in the proper ratio laid out in the owner’s manual for your particular chainsaw.
Different chainsaw manufacturers require different fuel ratio mixtures. Running the incorrect mixture can cause the chainsaw to either run too rich or too lean. Running rich means the fuel contains too much oil and can cause the unit to smoke, foul the spark plug or clog the muffler. Running lean means the fuel does not have enough oil and can result in the damaging of the engine by scaring the piston, cylinder, and rings.
STIHL, Husqvarna, Dolmar, Maruyama, and Echo typically require a fuel ratio mixture of 50:1 Poulan typically requires a fuel ratio mixture of 40:1 Please keep in mind that this is a general rule of thumb. Always consult your operator’s manual to be sure you have the exact fuel ratio mixture for your chainsaw.
Once you have determined the correct fuel ratio mixture you need to purchase the correct amount of oil for your chainsaw. You need to be sure to read the label for the volume of oil and the mixing ratio.
Refer to the chart below to make sure you’re using the correct 2-cycle fuel and oil mixture:
There are 2 more issues that need to be addressed with respect to fuel that most people do not realize.
The first of which is the age of the fuel in your gas can. Most people will mix fuel and let it sit in the garage for months. This is a formula for having a chainsaw that won’t run at all or at least won’t run correctly. Think of gasoline as you think of the milk in your refrigerator. You wouldn’t drink 3-month-old milk, would you? I didn’t think so. So why use 3-month-old fuel in your chainsaw? Gasoline expires the same as milk.
If gasoline is more than a month old, DO NOT USE IT in your chainsaw.
The second issue is the ethanol content in your fuel. What is ethanol you ask?
Ethanol, also known as ethyl alcohol is used as a biofuel additive in most of the fuel today. As a general rule of thumb, ethanol of up to 10% is generally ok for use in small engines like those that power chainsaws. Notice I said generally ok and not absolutely ok. Fuel with up to 10% ethanol will run fine but will cause issues with your chainsaw over time. These issues include the hardening and cracking of rubber and plastic materials like fuel lines, grommets, and seals. There is another grade of ethanol fuel known as flex-fuel that contains up to 85% ethanol.
Do not run flex fuel in your chainsaw. It will seriously damage or destroy the unit. Never run fuel with more than 10% ethanol in your chainsaw. At least not in the chainsaws we have today. I’m sure there are chainsaws being engineered that will be able to handle flex fuels just fine. However, they are not currently on the market for sale.
It is best to run ethanol-free gasoline, (if you can find it), with a high octane rating in your chainsaw. The higher octane-rated gasoline helps to combat things like pre-detonation within the engine.
What is the correct fuel mix for chainsaw?
The correct ratio of 2 cycle oil mix for chainsaws varies from brand to brand and must be strictly adhered to as to avoid damaging the chainsaws 2-cycle engine. What is the correct fuel mixture for your chainsaw?
Check with your chainsaws operator manual to verify the following information is still accurate as manufacturers update oil mix requirements from time to time
How much 2-cycle oil do you put in a gallon of gas for a chainsaw?
The correct amount of oil must be used to get the ratio of oil and gasoline correct in a 1-gallon fuel can. What is the correct amount of 2-cycle oil for 1 gallon of gasoline?
A chainsaw fuel mixture of 50:1 requires 2.6 oz of 2-cycle oil to be mixed in 1 gallon of gasoline. A mixture of 40:1 requires 3.2 oz of 2-cycle oil to be mixed with 1 gallon of gasoline.
Chainsaw’s 2 cycle engines are made with very tight specifications and run at very high RPMs that require properly mixed and fresh fuel. Always make sure that your gasoline is properly mixed with the correct ratio of oil for your particular brand and model of chainsaw. Remember that the wrong mix can destroy your chainsaw. Also, never use gasoline that has been sitting around for more than 1 month. Old fuel causes problems and it is best to just avoid it.
Have a great day and be safe.
Always be sure to only use EPA-approved fuel containers along with hand and eye protection.

Husqvarna Leaf Blower Fuel Mix Ratio
It is vital to use the right Husqvarna leaf blower fuel mix ratio.
If your engine has an excessive amount of oil, it may struggle to start or run, accumulate carbon, produce clouds of smoke, and generally perform poorly.
Alternatively, adding too little oil might result in internal engine damage and overheating.
The correct Husqvarna leaf blower oil mix ratio is specified in the owner’s handbook for your product. However, for Husqvarna models up to and including 75cc, a fuel-to-oil ratio of 50:1 is advised. This equals 2.5 fluid ounces of oil per gallon of gasoline. In some heavy-duty applications, engines larger than 75cc may be operated on a 33:1 mixture.
The ideal way to save money in the long run and truly maximize the performance of your Husqvarna leaf blower is to utilize AMSOIL SABER Professional Synthetic 2-Stroke Oil With this high-performance product, one single oil effectively covers ALL Husqvarna leaf blower fuel mix ratios.
While you can still use a 50:1 mix ratio with SABER you can get SUPERIOR performance and engine protection by using half the amount of oil at a 100:1 oil mix ratio!
- Excellent engine cleanliness and lubricity.
- Reduces friction and contributes to the prevention of plug fouling, wear exhaust port blockage, and ring sticking.
- Smokeless performance – produces fewer emissions at a 100:1 oil mix ratio.
- Maintains the stability of fuel during storage.
- Provides exceptional performance and protection at low mix ratios.
- For more detailed information, read the technical datasheet.
Let’s now go over why you’ll want to use a high-quality two-stroke oil like SABER in all of your prized lawn equipment.
Professional landscapers utilize their lawn equipment under harsh conditions and put their two-stroke equipment to the test. Whether they’re using string trimmers, backpack blowers, chainsaws, or other two-stroke lawn equipment, their working circumstances are very filthy, hot, and often damp. They are always on the go throughout the day owing to their demanding and unrelenting schedules that just do not allow for leisure. For these operators, it is critical to use the finest two-stroke oil for lawn equipment.
Running a landscaping and lawn care business is incredibly time-consuming. A typical landscaping firm must overcome several obstacles in order to have a prosperous year. Among the difficulties they face are high gasoline expenses, a scarcity of qualified personnel, rivals who charge absurdly cheap pricing for their services, personal stress, and very expensive health insurance costs.
A well-sized lawn and landscaping firm may operate between five and ten zero-turn lawnmowers, which cost on average 15,000 each. Additionally, this operation will include the use of eight or more string trimmers and backpack blowers. Each of these pieces of equipment will accumulate between 500 and 600 hours of use every year. This huge operation will need a significant quantity of gas and oil.
To operate a successful lawn landscaping company in such a fiercely competitive and difficult business climate needs a singular emphasis on cost containment and operational efficiency. Establishing a strict plan and then completing the work on time is crucial if you want to make a profit at the end of the day. Downtime is not a landscaper’s friend, and any malfunction can immediately upset the day’s tight schedule and wipe out the profit margin.
One critical approach that a lawn and landscape firm may use to help decrease downtime and increase revenues is to conduct an in-depth examination of the kind and quality of lubricants used. When it comes to lubricants for two-stroke machinery, there are noticeable disparities in quality. If the professional landscaper’s objective is to remain on schedule and maintain all equipment working effectively and at optimum capacity on a daily basis, the choice of lubricants may be simplified to just one. The only choice should be the finest two-stroke oil for lawn equipment, which should be a synthetic two-stroke oil that is 100 percent pure.
The finest two-stroke oil for lawn equipment must have exceptional lubricity, smokeless performance, significantly reduce or eliminate spark plug fouling, significantly minimize piston scuffing, mix readily with gasoline, and be highly concentrated to significantly reduce oil use.
The Best Two-Stroke Oil for Lawn Equipment
Reduces the Amount of Oil Required
To qualify as the finest two-stroke oil for lawn equipment, it is necessary and beneficial for such oil to assist minimizing the quantity of oil required throughout the year. Real money is saved by lowering the inventory required for two-stroke oil. For instance, AMSOIL offers a cutting-edge two-stroke oil named AMSOIL SABER Professional Synthetic Two Stroke Oil It is compatible with any mix ratio up to 100:1. When compared to more usual mix ratios of 50:1, mixing at this 100:1 ratio requires less oil.
AMSOIL guarantees a 100:1 ratio, which enables landscaping professionals to significantly minimize their reliance on two stroke oil, hence lowering expenses. Additionally, by using an 80:1 or 100:1 mixing ratio for all two-stroke machinery, you not only save on oil consumption, but also eliminate misunderstanding on the proper mix ratio to employ for varied equipment.
SABER Professional Synthetic Two Stroke Oil from AMSOIL reduces oil costs by 50% or more. Additionally, your equipment will maintain the highest level of performance and protection. With an 80:1 or 100:1 mix proportion, you benefit from greater protection and cost savings. You benefit from increased productivity and profitability.
Numerous landscape and lawn equipment businesses have complained about unusual smoking from their two-stroke gasoline engines. The excessive smoking is caused by the two stroke engine’s tendency to burn oil To help decrease or eliminate this smoking, various makers of two stroke oils have attempted to formulate an oil that either lessens or eliminates excessive smoking.
Again, let’s examine a premium smokeless two-stroke oil. AMSOIL SABER Professional Two Stroke Oil passed the industry-standard smoke test with flying colors when run at the recommended rich mix ratio. Smoke was undetectable when the SABER ratio was used in this test. Professional lawn and landscapers are constantly exposed to fumes and smoke, but they can benefit from SABER Professional’s low emission features by switching to a 100:1 mix ratio.
Not only does SABER Professional provide smokeless performance, it also protects and performs exceptionally well at 80:1 and 100:1 mix ratios, it can stabilize fuel during storage, it provides exceptional cleanliness and lubricity, it controls friction, and it protects against exhaust port locking, ring sticking, plug fouling, and wear.
Enhancing Engine Life and Performance
Selecting the finest two stroke oil for lawn equipment should and will result in improved engine performance and longevity. Using a two-stroke oil designed with high-quality synthetic base stock oils will undoubtedly provide advantages. AMSOIL SABER Professional Synthetic Two Stroke Oil has been tested and verified to burn cleaner than competing synthetic and mineral based lubricants. Its chemistry is unusual in that it works in synergy with synthetic base oils to reduce carbon deposits.
SABER Professional eliminates carbon deposits, which result in stuck piston rings, blocked spark arrestor screens, and clogged exhaust ports.
Stabilization of Fuel
Another important aspect to consider when selecting the best two stroke oil for lawn equipment is the oil’s ability to stabilize the fuel. When the season ends and the equipment is idle for the winter, it may be necessary to add a fuel stabilizer to the fuel to prevent it from degrading during storage. When the new season arrives, if no fuel stabilizer was applied and the gasoline deteriorated, the engine would run poorly. Of course, purchasing a gasoline stabilizer costs money, thus eroding the professional landscaper’s income.
What if there was an oil that eliminated the operator’s requirement for the price of purchasing a fuel stabilizer for storage? The answer is to use a premium, correctly designed synthetic two stroke oil, such as AMSOIL’s SABER Professional Synthetic Two Stroke Oil Its patented high-tech mix provides the advantage of fuel stability. By using SABER Professional you can avoid the deterioration of gasoline during storage.
Obviously, by avoiding the need to buy an extra gasoline stabilizer, you save money and improve your bottom line. When the season resumes, your SABER Professional-mixed fuel will be ready to go, and your engine will operate at peak efficiency and power.
This is another illustration of why it is vital to understand the lubricant’s ultimate cost. It’s always tempting to invest in low-cost two-stroke oils that operate at low mix ratios. On the surface, without knowing and comprehending all of the facts, synthetics, with their greater initial prices, may seem out of reach and unjustifiably expensive. The facts are obvious, however, that selecting the appropriate two stroke oil from a reputable synthetic oil producer like AMSOIL can actually save the professional money and end up costing far less than a cheap conventional or mineral oil based two stroke oil.
When considering whether to select mineral versus synthetic, an adage comes to mind: “Stepping over dollars to pick up dimes” is an apt statement when considering the whole cost of a product. The judgment is still out on synthetics vs. mineral-based oils. They will save the diligent lawn and landscaping company owner tens of thousands of dollars.
The normal two-stroke equipment lifetime for landscapers is two years. This two-year average is calculated on the basis of the usage of standard mineral-based two-stroke lubricants. For professionals that run a tight ship and adhere to a thorough maintenance schedule that includes AMSOIL’s SABER Professional Synthetic Two Stroke Oil replacing two stroke equipment every two years may become obsolete. There is documented evidence of certain two stroke equipment operating for more than ten years and accumulating between 6,000 and 8,000 hours of operation. This is entirely doable if the finest two stroke oil for lawn equipment is used. AMSOIL SABER Professional Two Stroke Oil is used in this instance.
Scuffing on pistons may be significantly decreased by using high-quality synthetics. For air-cooled engines that operate at substantially higher operating temperatures, using synthetics significantly reduces piston scuffing. Synthetic base stock oils outperform traditional two stroke oils in terms of lubricity. This higher lubricity contributes to wear reduction.
Logic dictates that a lubricant that performs smokelessly will likewise be easy to mix. If a lubricant has been confirmed to pass demanding and rigorous industrial testing and to work smokelessly, logical thinking dictates that this oil will provide better mixing experiences. It is vital that the oil be simple to mix in order to save time, but it must also function and preserve your lawn equipment. Proper and complete mixing is crucial to avoiding a rich combination at the bottom of the tank or a leaner mixture of primarily gasoline at the tank’s surface.
Please be aware that it is necessary to fully mix the two cycle oil and gas to minimize stratifications of oil and gas in the tank.
How to Remove Fouling from Spark Plugs, Pre-Ignition, and Exhaust Blockage
Oil makers conduct specialist industry testing to check for spark plug fouling, pre-ignition, and exhaust obstruction. Numerous conventional two-stroke engine oils have failed all three of these tests when run at a 20:1 fuel ratio. By selecting the finest two stroke oil for lawn equipment, such as AMSOIL’s SABER Professional you can ensure that the oil passes all three of these tests at the recommended 100:1 mix ratio. SABER Professional eliminates or significantly reduces pre-ignition, spark plug fouling, and exhaust obstruction.
It must be highlighted that only the best additive chemistry and base oils may be employed to produce a high-quality two-stroke engine oil that gives significant advantages. To believe that a low-cost traditional mineral two-stroke oil can provide anything more than the most basic and lowest protection is wishful thinking. For professional landscapers who are on a strict schedule and cannot afford any breakdowns, difficult choices must be made, and in the case of lubricants, the safest and surest method is to use only the finest two stroke oil for lawn equipment.
If you want to solve problems, adhere to deadlines, and optimize earnings, the most cost-effective answer is a high-quality synthetic two-stroke oil.

What is the Correct Gas to Oil Mix for Chainsaws?
Chainsaws can be expensive machines, and if you own one, you are sure to want to keep it in good working order. If you have a gas-powered one, part of this will mean always using the correct fuel – and since most chainsaws are 2-stroke models, this will involve mixing up the right gas-and-oil mix.
What is the correct gas to oil ratio for chainsaws? Why do you need to mix gas and oil like this? And what happens if you don’t? Here, we have the answers to these questions and more to help you keep your chainsaw running the way you want it to.
If you want a quick preview of some of the stuff we’re going to be talking about, check out this video that introduces some of the main concepts.
Before we get into mixing oil for your chainsaw’s fuel tank, let’s take a step back and think about why we need to do this at all.
Chainsaw engines come as either 2-stroke or 4-stroke versions. Sometimes these are also referred to as 2-cycle and 4-cycle engines – it’s the same thing.
Without going deep into the mechanics of how chainsaw engines work, a 2-stroke engine produces power for every two strokes of the pistons while a 4-stroke engine requires four strokes to produce power.
In a 4-stroke engine, on the third stroke, oil is taken from a special oil reservoir and brought into the engine to lubricate it. Since there is a separate oil reservoir and a stroke dedicated to lubrication, there is no need to mix oil into the gas the engine runs on.
However, in a 2-stroke engine, this doesn’t happen. There is no separate oil reservoir and there is no stroke dedicated to the lubrication of the engine – and for this reason, to keep a 2-stroke engine running smoothly, oil needs to be added to the fuel.
What is the Correct Gas to Oil Mix for Chainsaws?
There is no standard oil-to-gas ratio across engines, and you will need to check the manual for your particular chainsaw. However, most 2-stroke chainsaw engines, as well as any other similar power tools, run on a mixture that is one part oil to 50 parts gas, 1:50
However, many run on a ratio of 1:40, and other optimum ratios are possible – this is why it is essential to check the requirements of your machine.
So what does this look like in practice? Just to give an example, a 1:50 ratio of oil to gas works out at 2½oz of oil to each gallon of gas.
When you make your oil-and-gas mixture, take care to measure the amounts as precisely as possible. If you don’t get it right, you can easily end up damaging the engine of your chainsaw.
However, having said that, if you do make a mistake, it is better to have a little bit too much oil than not enough, so if in doubt, you can be slightly generous when adding the oil to the mix.
And what happens if you forget to add oil to the fuel you put in your chainsaw? You will know about it very quickly. The engine will start smoking within less than a minute and if you don’t shut it off immediately, it is likely to suffer irreparable damage.
How to make a gas and oil mix
If you have a chainsaw with a 2-stroke engine, you can easily mix up your own gas-and-oil blend to use as fuel. There’s no special technique, and all you’ll need is a gas can and something to measure the volumes.
First, pour the required amount of gas into the gas can. Carefully measure out the required amount of oil and pour it in after. Close the cap on the gas can and give the whole thing a good shake to make sure the gas and oil are properly mixed.
You can now use the mixture in your gas can to fill up your chainsaw.
General tips about gas engines
If your chainsaw hasn’t been used for a while – say, for a couple of weeks but less than a month – give the whole thing a good shake before you fire it up. If you leave it sitting, the gas and oil will separate it, and shaking the chainsaw will ensure they are well mixed before you start it.
If you don’t use your chainsaw for more than a month, empty the fuel and refill it with fresh fuel. Gasoline doesn’t age well, and after a month it will begin deteriorating to the point where the chainsaw no longer functions correctly. If you try to use old fuel, you risk damaging your chainsaw’s engine.
If you don’t want to mix gas and oil yourself, you can buy premixed fuel to save yourself the hassle. If you do, make sure you choose one that is suitable for your machine.
Make sure you know what kind of engine your chainsaw has. If it is a 2-stroke engine and you forget the oil, you will damage the engine. However, if you have a 4-stroke engine, you should make sure you only use pure gas – otherwise, you will also risk damaging your expensive chainsaw.
Quite separately from engine oil, chainsaws need oil for chain lubrication. This is true of gas-powered versions as well as electric chainsaws and cordless chainsaws. Make sure you don’t forget to lubricate the chain.
Always use the right ratio
As we said, while the most common oil-to-gas ratios are 1:50 or 1:40, there is no standard, so you shouldn’t just guess. Make sure you find out exactly what ratio your chainsaw’s engine requires and mix it up carefully and precisely. Similarly – and this goes without saying – make sure you know whether you are running a 2-stroke engine or 4-stroke engine before filling the tank and firing it up.
Chainsaws are expensive tools, and failing to use the right oil-and-gas mix – or pure gasoline in the case of a 4-stroke engine – is the quickest way to send you valuable machine straight to the scrapyard.
