Cons

The app calcs well but don't understand how % of tank is accurate. If Ford % remaining doesn't factor 4 gallons for reserve what do I input?

This app is definitely the best out there, thank you for making our lives easier. I am saying this as a recommendation for a small feature. I’m not sure if others have the same problem, but it would be nice to be able to set the target fuel amount in the tank. Right now, the calculator gives you the number of gallons to add in order to get to a full tank. But for those that are racing competitively and maybe don’t want the added weight of a full tank, it would be nice to say, for example: “I want 1/2 full of a tank and I’m at 1/4, how much ethanol and pump gas do I need to add?” Hopefully that make sense. Thanks!
