Pre-Mix - It's the easy way to calculate oil to fuel mix ratios. App Reviews

This is a great app for calculating fuel/oil ratios. No more guessing when I need to top off the boat. Just set the ratio and enter the gallons. Simple.

The slide scale takes several attempts lock in # of gallons. Have # you want, then when you remove finger, # changes. How about a roller wheel? Its a very handy app. The oil bottles dont always have the ratio info I need.

Slide is sensitive, hard to get it locked in. Very helpful when filling up the 2 stroke at the gas station and want to add oil at the same time. Would like a "favorites" to save specific ratios.

Nice simple easy to use app

If stupid people would use the + - on the ratio bar it would work great for them.

Works perfect!! Simple and easy to use.

Finally an easy way to do the math so my small engines dont get blown up and carbd up.

This app had made my life just a little easier. It is spot on and easy to use. Would recommend to anyone

The app is exactly what it says it is.. It would be easier if you could just type your ratio in. Please change and it will be great!

exactly what i needed you can put any ratio and the gallons you will use etc app will tell you how much oil you need , thanks for the app developer! :)

Im a 100%, Combat Disabled Marine with TBI and this app works perfect for me. With my TBI, I need to double check my numbers most of the time. This app helps me with my dirt bikes, chain saw, weed trimmer, etc. different ratios.

Does what it is supposed to. Quick and easy. Metric or standard. Up to 100:1 ratio. Worth the .99 cents.

Driving a two stroke car, this app is very simple and user friendly.

Its small, tight and works as advertised. In the next version I hope it gets iPhone 5 support; with the Extra screen space, there would be room for having a couple of favorites. For example, the boat is 50 and the trimmer is 40; under the gas entry, you could have a few (maybe 2 or 4) boxes with the most popular ratios or user-defined ratios. Easily worth more than a buck.
