Two-cycle engines run on a mixture of gasoline and oil. Each engine type is designed to run on a specific gas-to-oil mix ratio. To confirm the correct ratio for your equipment, check your Operator's Manual.
IMPORTANT: Use only oil that is labeled for use in “Two-cycle” or “Two-stroke” engines. Two-cycle oil is available at most major retail stores, automotive supply stores, and our Online Parts Store as part number OL-28.
NOTE: Synthetic oil is perfectly fine to use, but it must be mixed in the exact ratio specified for the engine. Do not follow any instruction on the oil package that says otherwise.
To mix two-cycle fuel, start by putting the correct amount of oil in the gas can. Then slowly add the correct amount of gasoline. Do not try to mix the gas and oil directly in the gas tank of the equipment.
IMPORTANT: Do not use any fuel that is over 30 days old. Do not mix more fuel than you are likely to use in a month. Click here to learn about issues related to old fuel.
What fuel mix do I need?
Always refer to the product engine Operator's Manual for the correct ratio for that engine.
The chart below shows the correct amount of oil per gallon that each mixing ratio requires.
It also shows the amount per Imperial Gallon and per Liter for our *International customers located outside of the United States.
