Oil to Gas Ratio Calculator

The Oil to Gas Ratio Calculator is a tool used in two-stroke engines, such as those found in chainsaws, lawnmowers, or outboard motors. It helps determine the correct ratio of oil to gas that should be mixed for optimal engine performance and lubrication.

Formula

The formula is straightforward: divide the amount of oil by the amount of gas to obtain the ratio. This ratio is usually expressed as parts of oil per parts of gas or as a ratio fraction.

Oil to Gas Ratio = Amount of Oil / Amount of Gas

Example

Example: If you have 40 milliliters of oil and need to mix it with 1 gallon (approximately 3785 milliliters) of gas, the ratio would be:

Oil to Gas Ratio = 40 mL / 3785 mL = 0.0106 or approximately 1:95
