30 to 1 Fuel Mix Chart

Thirty to one (30:1) is a ratio used by some older 2 stroke motors. The ratio is not the easiest 2 stroke ratios to calculate.

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

Fuel (L)Oil (mL)
133
267
3100
4133
5167
7.5250
10333
15500
20667
25833

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?
