Fuel Oil Mix Calculator is a practical Android app developed by VMSoft, designed specifically to assist in determining the precise amount of oil required for fueling 2-stroke gasoline engines. Users can input their desired mixture ratio or select from a list of pre-defined vehicles, enter the quantity of fuel, and with a simple click, obtain the exact oil amount needed for the mix.

This app boasts features like custom mixture ratio settings, a convenient 'Vehicle Editor' for managing all 2-cycle gasoline equipment, support for both US and metric units, and an option to prevent the screen from turning off while in use.
