This gas/oil ratio calculator can be used for determining the amount of oil needed for any gas/oil ratio required by the manufacturer's instructions for two-stroke engines.

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.

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.
