E85 Mix Calculator

App doesn't tell you what base octane your using for example I mix 91 with E85 and I believe this app only shows a mix with 93 octane

Now, i dont need to wait until my tank gets empty.

perfect, the only one of all the ones ive tested that works and has a real formula that is right!

Great app for those who have done a tune for E30 (currently own a 2015 Mustang Ecoboost with an E30 tune). Very simple and easy to calculate, a must have program 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.

What I'd like to see added is a second tab where you enter what you actually put 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 help 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 get x or y qty of fuel in the tank vs what's needed.

I just tuned my car to run an e85 mixture (e33) and this app 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 keep a solid 33% mixture. Definitely a must download. Thank you.

Exactly what I needed. I like to make my own e60 blend. Thanks Dev!

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

This is the only app in the market of it's kind and it's immensely useful. I do wish 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 other fields. 3. Wider fields so 12.25 wouldn't get cut 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 little of either.

Takes away the headache at the pump, only app of its kind that I have seen so far. Makes going from pump gas to E30 way easy. Now I don't have to wait to run my tank empty before filling up. Perfected for those with boosted cars.

Works exactly how it should. Great app.

Awesome app!

Awesome app

This is the best app ever Bought it used it and love it. I use it for all my mixtures. Completely satisfied.

If you're reading this then you already know what this tool is used for. This app is simple and works flawlessly.
