Easy Oil
Version 2.08

Easy Oil is an oil to fuel mix calculator.

Use it to estimate the oil to fuel mix ratio for 2 cycle engines from 16:1 up to 100:1.

To operate just slide the Oil Mix Ratio slider to the ratio you need.

Slide the Fuel Slider to number of gallons in your tank.

The needed amount of oil will appear at the top of the screen along with the Fuel amount and Oil ratio you have chosen.

The Fuel slider has a capacity of 100 gallons.
To calculate for more fuel just calculate in sections (ie; for 75 gallons calculate for 50 gallons and then 25 gallons).

• Use the Units of Measure button (little fuel pump) to set the preference between Liters or Gallons for the fuel measurement unit.

• Equipment List page where you can enter notes on up to 8 pieces of equipment like boats, snow blowers, lawnmowers and chain saws.

Works great, one issue

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.

Sliders Disappeared and doesn't save settings

When I open the app the slider buttons disappear. 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

Works great, good for odd mixtures

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
