oilCHECK

Enter the flight time of your last flight, enter the oil level status of your airplane engine and the amount you refilled - and get the average oil consumption of your engine.
You can also set Oil Changes and the app will tell you how long you have flown since the last oil change.
Turn your device by 90 degrees and see a graph that shows the average oil consumption per flight. After every Oil Change a new page is created and you can scroll through them horizontally.
