Then they don't respond. Very glitchy. The data it gives when it does work is great. Especially for odd amounts of gasoline. But fix the sliders dudes. I'd give it a 5 star review if they weren't so glitchy and sensitive. Also I should be able to set my default fuel and ratio amounts. This app always goes back to 6 gallons. Fix the bugs please. I want to use this app. I have a lot of 2-cycle Equipment. Sincerely Pat ### 4/5 — Works great, one issue *2012-05-17, version 1.1* The app works as advertised and is fast and easy. However, the sliders are too sensitive to the touch. I had to struggle for almost 5 mins to get the slider to remain on a 40:1 ratio as it would move to another value as soon as I lifted my finger off of the screen! Either dampening the sensitivity of the sliders some, or adding the ability for manual entry of values would really help. ### 5/5 — Works great, good for odd mixtures *2009-11-15, version 0* Oil and gas mixtures are easy to figure out but when you have odd gallons and different mixtures this app comes in handy. Simple slide allow you to adjust the gallons of gas and the oil mix ratio and the results are instant. Im often stuck with 3 gallons or 6 gallons of gas and need 40:1 or 50:1 for different machines. Well worth the small dollar price for the speed. Beats using a calculator or sheet of ratios ## Frequently asked questions about Easy Oil ### What is the oil to fuel mix ratio range for Easy Oil?
