What kind of gasoline to pour into a chainsaw, which is suitable for increasing efficiency

In this article, you will learn what kind of gasoline should be poured into a chainsaw, tips on using oil for a chainsaw, and how to prepare a mixture of oil and gasoline for a saw.

What kind of gasoline should I put in my chainsaw?

Firstly, it must be said that the brand of oil and which gasoline is best suited for your chainsaw are written in the instructions for it. Manufacturers always indicate this in the technical specifications of the device.

We recommend filling the chainsaw with unleaded, high-octane and fresh AI-92 gasoline.

Gasoline wears off. If it is left for four months and then poured into the engine, it will affect performance. During this period of inactivity, gasoline decomposes so much that it begins to burn/ignite 30% worse. Stale fuel produces more carbon deposits and is more explosive, so use only fresh fuel.

The chainsaw engine is not prepared to work with low-octane and leaded fuel. Using such gasoline will greatly shorten the life of the saw. There may also be increased wear of parts and the possibility of explosion. If you use such fuel, take frequent breaks from work.

Why is AI-92 poured into chainsaws?

Chainsaw engines are low-power and not all types of fuel are suitable for them. That is, their internal combustion engine operates with gasoline that contains only certain impurities.If there are other impurities or a different ratio, it may cause an explosion. For example, AI-95 is a high-octane, high-quality, elite gasoline. AI-95 is better from a safety point of view - it contains impurities that prevent it from detonating. But due to these same impurities, the performance of the chainsaw engine can decrease and the wear of elements can accelerate. A parallel can be drawn between pouring such gasoline into a saw and using rocket oil in a car.

The use of lower octane fuel is prohibited due to the risk of explosion.

Choosing chainsaw oil

We also advise you to look at the instructions. It indicates everything the user needs to know: what gasoline to fill, what oil to use, when to carry out a technical inspection, what and when to replace, and more.

If there are no instructions, you can use our tips for choosing chainsaw oil:

• Use oils of different densities, depending on the time of year and temperature.
• Do not add oil for four-stroke engines - you will break the engine.
• In the warm season, chainsaw oil should contain metal additives.
• Distinguish oils by color: green – synthetic, blue – semi-synthetic, red – minerals.
• In winter, use synthetic analogues - synthetic oils freeze at temperatures of -30/-40, mineral oils already at -20.

How to prepare a fuel mixture for a chainsaw

1. Take a measuring container - it is better to use a transparent plastic bottle with oil/product markings, in them you will see how the liquids are mixed and you will not need to pour fuel again.
2. Fill it with fresh, high-octane, unleaded gasoline and oil in a ratio of 50 to 1 (some models need 40 to 1), where 50 is the ratio for gasoline, 1 for oil.
3. Shake/stir the mixture. It should become the same color.
4. Fill the chainsaw tank with fuel.
