## Details

Mixing 2-stroke fuel is simple arithmetic that people get wrong in expensive ways: too lean and a chainsaw can seize, too rich and the plug fouls. 2-Cycle Oil Mix Calculator gives the exact answer. Enter your gas in US gallons or litres, pick 100:1, 50:1, 40:1, 32:1, 25:1 or 20:1, or type any ratio, and it shows the oil to add in both ounces and millilitres.


Flip to Oil to Fuel mode to go the other way, and copy a link to share a mix. Equipment pages give the usual ratio for chainsaws, trimmers, leaf blowers, lawn mowers, dirt bikes and outboards, and printable charts cover the common ratios for the shed wall. It is a free, independently run tool with no accounts, no paywall and no app, in English and Spanish.
