Need to calculate the oil/petrol(gasoline) mixing ratios for use with 2 stroke (2-cycle) engines? Then this tool is for you. Can be used with either outboard motors, radio controlled vehicles or items such as chainsaws. The app determines the volume of oil to add to the amount of gasolene/petrol you have based on the recommended mixing ratio by the engine manufacturer.
For these engines, petrol must have oil mixed with it, or you risk burning up the engine. If not enough oil is present you risk damming the engine, and too much oil can foul up the engine.
NOTE: version 1.0.0 has a slight bug. selecting Litres or Gallons US produces inverted result. A v 1.0.1 fix is being loaded to Apple for approval.
