About Oil to Gas Ratio Calculator (Formula)

The oil to gas ratio is the proportion of oil to gas in a mixture, typically used in internal combustion engines, such as those found in small aircraft, boats, and some types of power equipment. The ratio is usually expressed in terms of the number of parts of oil per part of gas.

The formula for calculating the oil to gas ratio is: Oil to Gas Ratio = Oil (gallons) / Gas (gallons)

It’s important to use the correct ratio for the specific engine and operating conditions. The oil to gas ratio is different for two-stroke engines and four-stroke engines, and also depends on the engine’s size, usage, and the climate in which it will be operated. In general, a higher ratio of oil to gas is used for two-stroke engines and a lower ratio for four-stroke engines.

It’s also worth noting that there are other ways of expressing ratio. Some manufacturers use a ratio like 50:1 which means 50 parts of gas to 1 part of oil. And the oil to gas ratio can also be expressed as a percentage, like 16% oil to 84% gas.
