This calculator requires the use of Javascript enabled and capable browsers.
* There are two calculators - one for standard (USA) values and one for metric values.
* These calculations determine the exact quantity of oil required for a given ratio of gas and oil suggested by the manufacturer of the engine.
* The calculated number is determined from the amount of gas available for the mixture. That amount is usually an added number, such as 4 gallons, 5 gallons, 10.2 gallons or similar.
* Enter the number of US gallons of gas added to the tank; the default is 5 gallons. Then, enter the mixture ratio of gas to oil. If you are uncertain,consult your owners manual.
* Enter the ratio value or accept the default.
* Click on the Calculate button to find out how many US ounces of specified two cycle oil (or whatever the oil type requirement is for your engine) are required.
* Calculations in either calculator will also supply the appropriate converted values for the other.
* For 5 gallons of gas, with a 32:1 ratio, the amount of oil required is 20 US ounces (156.25 ml), 4 ounces per gallon of gas (31.25 ml per liter).
* Experts agree that it is better to err toward the side of too much oil, rather than not enough.
* We suggest following your RC Aero Products Engine manual guidelines or if you are using an engine that is not ours then follow the manufacturers recommended guidelines.
