How to mix gas and oil for chainsaw fuel

The quality and proper mixture of gas and fuel is important to make your chainsaw engine run and to protect your engine. The manual that comes with your chainsaw usually has this information. The wrong type of fuel and oil or the wrong mixture will cause serious damage to your engine.

Almost all modern two-stroke engines use a ratio of 1:50. This is 2 1/2 ounces of oil per 1 gallon of gasoline. Make sure that you use a two-cycle oil for your mixture. This oil is specifically made for the chainsaw engine. Pour the correct amounts in a gasoline can and shake it well to ensure it is properly mixed. Pour the engine oil first.

If you pre-mix your fuel and store it, the oil will rise on top of the gas. Shake it before pouring it on your gas tank. Make sure that your fuel is still fresh.

If your chainsaw is used more often than normal, a mixture of 1:40 will help better lubricate your engine. That will be 3 1/2 ounces of oil for every gallon of gasoline.

Some people use a ratio of 100:1. There is a difference of opinion on this topic. However, the standard is what’s mentioned above.

The quality of the oil you use is more important than the small difference in ratio. Always use quality two-stroke engine oil that complies with the TC qualification.
