Mixing the right amount of oil-to-fuel to run your gasoline engines helps with its performance and longevity. So, I always try to follow manufacturer's recommendations when running my engines.

I run many small gas engines in my hobby (RC airplanes). From small 9cc to 50cc and many others that fall in between including 4-stroke gassers. I also run some grass trimmers, generators, etc. Many of the engines have different fuel-to-oil mixing ratio requirements.

This App simplifies the mix requirement calculations. You can specify the volume of fuel (in Liters) or specify the dollar value (${'$'}) of fuel purchased to mix.

Being not a commercial purchaser, I usually procure my fuels from gas/petrol stations. Gas stations, at least where I am, usually sell fuels by dollar value rather than by volume to avoid dealing with change. As such, it’s easier to just pump a certain value and calculate the mix required based on that value rather than try to remember the actual volume pumped.
However, if you split the batch to mix multiple ratios to accommodate different engines, you can then use the” Volume” calculation method.
Custom mix ratios are accommodated by the App, as well as calculations for fuel additives. I use fuel stabilizers as I usually procure enough for a couple of months use at a time.

If you only use one method to calculate, check out my single page apps with different colored caps. (e.g. Red cap for 1 page/value entry/metric)

Thank you and hope you find this App useful. Any feedback, comments or suggestions are welcome.
