Yes, you can use 89 octane gas in a 4-cycle small engine, as it is generally compatible with higher octane fuels. However, most small engines are designed to run on regular 87 octane gasoline, so using a higher octane fuel may not provide any additional benefits and could be more expensive. Always check the manufacturer’s recommendations in the owner’s manual for the best fuel type for your specific engine.
