2-Cycle Oil Mix Calculator

2cycleoilmixcalculator.com is a free online calculator for mixing 2-stroke (2-cycle) fuel. Enter the amount of gas in US gallons or litres and a mix ratio such as 50:1, 40:1, 32:1 or 25:1, or type a custom ratio, and it gives the exact amount of oil to add in both ounces and millilitres. A reverse mode works out how much fuel a given amount of oil makes. The site also publishes printable mix ratio charts in US and metric units, pages on the usual ratio for chainsaws, string trimmers, leaf blowers, lawn mowers, dirt bikes and outboard motors, an FAQ and guides on mixing 2-stroke fuel. It needs no account and no app: the calculator runs in the browser. English and Spanish versions are available.
