7 Positive User Reviews for E85 Calculator

Decent, but one flaw

Used this a few times. It works, but absolutely hate that I have to refill information every time I load this app. It does not save previously saved info. For example, tank size or desired E% rating.

Spot on

Not going to lie it took a bit to get use to but once u get it down it's a life saver for people who have a fuel percentage slot on their car/tuner. Cross checked it with some other online e85 calculators and it's pot on 👌

Love the app. Just wish one thing.

Terrific app!!! Only wish there was a "save custom settings" feature, so those of us with custom tunes can save the percentage of Ethanol we run. Fyi. Arizona only has E54 now. I'd like to set that at default as well as my tank size and desired E%, when I mix.

Needs save certain fields.

You said it was coming almost a year ago. Thanks.

Pretty good but..

2/2/16 Update: has a bug that makes the app display 9% more ethanol mix than desired goal Needs 2 things 1) to save input data in memory. 2) to fix bug where octane is affected by changing ethanol % and requires gas octane to be ready entered to reset. Also, needs to calculate the octane based on the e85 pumps octane (via input) and not just the octane of e85(105). Ex. it needs to compensate for the total change away from e85, if I input the station only gives out e81 at their statio

App works great but needs a save feature

A year ago the developer said there was an update coming out to save custom settings. Still needs that update. For a paid app there should be support.

Needs work

I can’t see though my tank and measure how many gallons are remaining in my tank. Needs to be simplified to tell me how many gallons I need to add to my tank to get desired octane.
