20 to 1 Fuel Mix Chart

Twenty to one (20:1) is one of the easiest 2 stroke ratios to calculate, you simply multiply the litre amount by 5 and add a zero.

To make it easier you can use the following old school reference chart.

Fuel (L)Oil (mL)
150
2100
3150
4200
5250
7.5375
10500
15750
201000
251250

If you’re looking for something to help with other ratios and remind you how old your fuel is, please take a look at our app for iPhone and Apple Watch on the front page?
