Chainsaws typically require unleaded gasoline as their fuel source. It is recommended to use mid-grade unleaded gasoline with a minimum octane rating of 89. Using fuel with a lower octane rating may increase engine temperatures and risk damaging the engine.
Key Facts
- Fuel Type: Chainsaws typically require unleaded gasoline as their fuel source.
- Octane Rating: It is recommended to use mid-grade unleaded gasoline with a minimum octane rating of 89[3]. Using fuel with a lower octane rating may increase engine temperatures and risk damaging the engine.
- Two-Stroke Engine: Many chainsaws are powered by two-stroke engines, which require a mixture of gasoline and two-stroke oil. The fuel mixture is important for proper lubrication and performance of the chainsaw.
- Mixing Fuel: When mixing fuel for a two-stroke engine chainsaw, it is crucial to follow the manufacturer’s instructions. Typically, the fuel should be mixed in a clean fuel container, not in the chainsaw’s fuel tank. The recommended mixing ratio for Stihl chainsaws, for example, is 50 parts gasoline to 1 part 2-cycle engine oil.
- Fuel Storage: It is advisable to only mix enough fuel to last for one to three days at a time to keep the fuel fresh and minimize the risk of buildup. Fuel should not be stored for longer than three months and should be kept away from anything flammable and your home.
