25 to 1 Fuel Mix Chart

Twenty five to one (25:1) is one of the easiest 2 stroke ratios to calculate, you simply multiply the litre amount by 4 and add a zero.

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

Fuel (L)Oil (mL)
140
280
3120
4160
5200
7.5300
10400
15600
20800

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?
