Gasoline, as well as engine oil and chainsaw chains play one of the key roles for the stable operation of the tool. The durability of the main working mechanisms of the saw depends on their quality and properties, therefore, the choice of fuel and lubricants should be treated with special responsibility. The regular use of high-quality lubricants and fuels is the main guarantee of the long-term operation of the chainsaw without its unforeseen breakdowns.
What kind of gasoline to fill in a chainsaw?
When choosing the right fuel, each owner of the tool should build on the brand and country of manufacture of the model on the farm. Old domestic saws called Ural and Friendship are best filled with AI-80 grade gasoline. It contains precisely those additives that are necessary for the stable operation of unpretentious domestic engines. modern domestic models are designed to operate on the 92nd gasoline.
Things are a little different with imported chainsaws. The engines of all these models are designed for more gentle fuel, so German, Swedish, American and Japanese chainsaws need to be filled exclusively with gasoline, AI-92.
An important role in choosing gasoline is played by its condition. Many novice gardeners are confident that fuel can be poured into the saw’s fuel tank, which can be kept in the canister for a long time. Some people think that the tool works in constant dust, and it is because of this that manufacturers have provided a special air compensator in the carburetor, which works when the air filter is worn.
This opinion is fundamentally wrong. As a result of a long stay in the canister, gasoline loses its main properties, and its composition, depending on the material of the container, is replenished with plastic molecules or metal rust.
Due to a long stay in the canister, gasoline begins to lose its fumes, and it is they that ignite when the chainsaw starts. It is because of this that gardeners face a number of typical problems, which include:
- difficulty starting the motor;
- rapid drop in engine power;
- accelerated wear of tool elements.
To prevent this, you need to regularly use only fresh fuel from proven gas stations. It is best to buy 2-3 liters of gas every morning before starting work in the garden. The use of fresh gasoline will facilitate the launch of the chainsaw, and significantly extend its life.
Is it possible to pour 95 gasoline into a chainsaw?
In almost every instruction manual, you can find instructions from manufacturers that for regular refueling of household tools you need to use gasoline with a constant octane rating of no higher than 92. Despite this, many beginning gardeners continue to refuel their saws with 95th gasoline, in vain believing that he is better.
It should be remembered that the engines of all imported and some domestic tools were originally designed to operate on 92nd gasoline. If 92-th gasoline is poured into the instrument’s fuel tank, this will lead to a push of the piston into the counter-flow, which is often called detonation. This dangerous process will become cyclical, and will be repeated at each revolution of the ICE crankshaft. Probably, it is not necessary to say that the use of 98th gasoline will even worse affect the operation of the piston and the condition of the engine of the chainsaw.
Two-stroke engine oil for chainsaws
Modern gasoline saws can be equipped with 2-stroke or 4-stroke engines. In the latter, the oil initially enters the parts of the crank group directly from the crankcase.
In contrast, in two-stroke factory engines, fuel enters the plane below the piston. To refuel such chainsaws in fresh gasoline, you need to add engine oil. It lubricates friction parts of the engine, preventing their premature wear.
Oil for 2-stroke chainsaw engines must necessarily meet a number of important parameters:
- when burning oil, a minimum amount of ash should be formed. It is best that the oil used burns in full;
- the lubricant should dissolve quickly in gasoline;
- 2-stroke engine oil must be cleaned of harmful impurities, which can lead to blockages in the carburetor lines.
The choice of oils for 2-stroke engines largely depends on the types of cooling systems. For lubrication of ICE equipped with air cooling systems, 2T standard compounds are suitable. For motors cooled by liquid systems, oils marked TC-W3 should be selected.
In any case, the oil for the permanent lubrication of the engine of the tool used must have the highest quality. Poor-quality oils during combustion form a large amount of soot, which settles on the walls of the cylinder and under the piston rings of the engine. Because of this, the standard rings lose the ability to shrink, as a result of which burrs appear on the inner walls of the engine cylinder. In addition, poor-quality grease leads to overheating of the parts of the crank mechanism. As a result of this, they jam and completely fail.

How to dilute gasoline with chainsaw oil?
A mixture of gasoline and oil should be constantly prepared in a clean container, on the walls of which there are measuring marks. This will give the owner of the chainsaw the ability to accurately determine the amount of gasoline and engine oil they mix. The material of which the container is made must be resistant to gasoline. Metal vessels are well suited for this.
Fill fuel and lubricant through a watering can to prevent loss of components. In order for the grease used to completely dissolve in the fuel, the filled container will need to be shaken several times. As a result, the gasoline mixture should become evenly colored. In this case, it must be ensured that there is no precipitation at the bottom of the vessel.
The ratio of oil and gasoline for chainsaws
Each chainsaw company customizes engines and base carburetors to handle varying amounts of lubricant. Therefore, the proportion of oil and gasoline for a chainsaw may vary slightly.
Most often, when mixing fuel with oil, manufacturers advise using proportions of 1:50, or 1:40. This means that 1 part of motor lubricant needs to be mixed in 50 or 40 parts of fuel, respectively.
Converting a proportion to a more accessible wording is quite simple. For example, 1 liter of fuel contains 1000 ml. If 1000 ml divided by 40, then get 25 ml. This means that for 1 liter of gasoline you will need to dilute 25 ml of lubricant. The same formula should be used when the manufacturer recommends preparing the fuel mixture exclusively in a proportion of 1:50. To do this, 1000 ml must be divided by 50, resulting in 20 ml. This means that in one liter of fuel, 20 ml of motor lubricant should be diluted.
Things are slightly different with Chinese chainsaws. Their manufacturers are advised to breed gasoline for chainsaws in a ratio of 1:25. This means that owners of Chinese tools need to mix exactly 40 ml of a lubricant in 1 liter of pure gasoline. This ratio is due to the fact that these chainsaws are slightly inferior to their Western counterparts in terms of build quality and selection of components. In engines of American, European and Japanese models, the distance between the cylinders and pistons is much smaller than that of chainsaws from China. In this regard, the amount of lubricant required for the first to work. far less.
Which oil to use for chainsaw chains?
To know exactly what oil to use to lubricate the chainsaw chain, you will need to study the instructions of its manufacturer. Almost all manufacturers of tools recommend pouring a tool that stands out with the highest adhesive properties. This means that the material used to lubricate the chain must adhere to the metal surfaces of the chain and tire.
You need to figure out why the lubricant has adhesive properties. When the chain moves along the standard tire, the saw element reaches high speed. If, for lubrication purposes, you use chain oil for a chainsaw, which has low adhesion, then more than half of the fluid will fly by inertia from the top of the tire, never reaching its bottom. As a result, such an oil will prove ineffective, and the tire, along with the chain, will quickly fail due to constant friction.
The best oils for chainsaw chains
You can find the highest quality oils on the market, which are recommended by almost all manufacturers of chainsaws and manufacturers of saw sets for them. These products are characterized by high adhesive properties, which makes them effective when working in difficult weather conditions. These lubricants include:
- Stihl ForestPlus oil. this composition is best used at an air temperature of at least.15 ⁰ͦC. On sale, the material is supplied in containers with a capacity of 1 or 5 l;
- Stihl SynthPlus grease. has high adhesion with metal coatings. The composition shows high efficiency when working in conditions no lower than.25 ⁰C;
- Husqvarna Bio Advanced oil. shows itself equally well, both in normal and in extreme conditions. The product has a balanced composition with improved adhesive properties;
- Makita Biotop grease is one of the top products. reliably protecting the saw parts of the tool from increased friction and premature wear. The price of this oil is much lower than Stihl products;
- Oleo-Mac Polar Lube is a low-cost lubricant that stands out due to its low price and excellent viscosity and adhesion parameters.
To lubricate each of these products, manufacturers advise using no more than 5 mg of lubricant per cycle.
Chainsaw sprocket oil. manufacturers tips
In order to reduce the friction of the drive sprocket and extend the life of the mechanism, each manufacturer equips it with a needle bearing, which needs periodic lubrication. Many experts advise using the multi-purpose composition of the Stihl brand for this.
This tool is quite expensive, so some gardeners and professional forest fellers use lubricants at a lower cost. Compounds such as Litol or Litol 24 have proven effective against the high friction of a needle bearing.
The same oil can be used to lubricate the driven sprocket of the chainsaw, as well as to protect the drive sprocket. A small syringe is suitable for their application. It quickly presses the lubricant into the small holes in the tire and next to the bearing located above the sprocket.
