The app is smart and it will remember your tank capacity and target ethanol mix values so next time you want to see how much E85 you need to add to get your target ethanol mix, you will only have to specify your current tank percentage. This way it is the fastest method to calculate how much gas and e85 you need to put in the tank. It is such a fast method, by the time you get out of your car, you already know how much fuel you need to add in the tank. Literally 3 seconds.

The app is completely free and has no ads!
With this app, I hope to help the tuner community and the hardcore car fans.

Additional Information:

You have the option to select what your current ethanol content is if you measured it with an ethanol content analyzer and the app easily calculates how much E85 and how much gas you need to add to reach your target ethanol mix.

You can also specify the ethanol content of your E85 if you measured it with an Ethanol Content Analyzer, so this way you get an exact guide as to how much E85 and how much gas you have to put in the tank.
