50 to 1 Fuel Mix Chart

Fifty to one (50:1) is one of the easiest 2 stroke ratios to calculate, you simply multiply the litre amount by 2 and add a zero.

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

Fuel (L)Oil (mL)
120
240
360
480
5100
7.5150
10200
15300
20400
25500

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?
