  A Google user: Takes away the headache at the pump, only apk of its type that I have seen so far. Makes going from pump gas to E30 method simple. Now I don't have to wait to run my tank empty before filling up. Perfected for those with boosted vehicles.

  A Google user: Good apk for those who have done a tune for E30 (currently own a 2015 Mustang Ecoboost with an E30 tune). Very easy and simple to calculate, a must have tool for those who are at the pump and still need to be around the ethanol rate and not go over or under the desired fuel mix.

  A Google user: I just tuned my vehicle to run an e85 mixture (e33) and this apk is tremendously useful! It really takes the mathematical headache out of filling up at the station. No matter how low my tank is I can hold a solid 33% mixture. Definitely a must download. Thank you.

  A Google user: Does what it says. Calculation is spot on. Saves me lots of maths at the fuel station. Would be good to have an octane calculation feature.

  A Google user: This is the only apk in the shop of it's type and it's immensely useful. I do want it had a few features: 1. The ability to lock the fuel tank size so an errant tap didn't clear it. 2. Same thing for another fields. 3. Wider fields so 12.25 wouldn't receive slash off, for example 4. The ability to work backwards from volume of gas and volume of e85 added to determine ethanol content of tank. Useful if you add too much or too tiny of either.

  A Google user: Apk doesn't tell you what base octane your using for example I mix 91 with E85 and I trust this apk only shows a mix with 93 octane

  A Google user: Please fix the Calculate button. It moved some time ago and now covers some of the fields.

  A Google user: What I'd like to see added is a second tab where you enter what you actually place in the tank. This tab would calculate the actual e value in the tank. Then the next time you fill up you can pull that e value and use it on the original tab for e value in the tank. Over time this will assist maintain a better estimate of e value. The reason I say this is you can pull the fuel level % from your tune device and do the calcs but sometimes you only receive x or y qty of fuel in the tank versus what's required.

  A Google user: This is the best apk ever Bought it used it and love it. I use it for all my mixtures. Completely happy.

  A Google user: So I really do like this apk and it works perfectly for what I need but... The calculate button is in the value Fields now and it has been for a tiny while and it's type of annoying. Also longer fields so the numbers don't receive slash off would be very nice but another than that if those two things should be fixed it would be a definite five star apk.
