Fuelwiz

A simple calculator for when you need a mix for your boat/mower or other 2 stroke fuel guzzler. You have x amount of petrol but unsure how many mils of oil to add to it to get a 40/1 mix? Just put in the value in litres, choose the mix ratio and hit calculate.

Just to make it more useful it also lets you input an amount of oil you have lying around and lets you find how many litres of petrol would be required to achieve your desired mix. It's free and it works, all you need. No ads.

FuelWiz2 is now free, go get it!

Supports US and UK Gallons, Pints and Ounces. ICS4 features for a better looking app and a page to store your 2 stroke item details.
