Fuel mix

Gas/engine oil Mix

Your gas powered engine requires a mixture of gasoline and engine oil to operate. The quality of the gasoline and oil is extremely important to the running and life of the engine.

Unsuitable fuels or mix ratios that do not comply with the specification can seriously damage the engine (piston seizing, excessive wear.). For optimal performance we recommend STIHL Premium 50:1 mix engine oil available at your local STIHL Dealer.
