A system for establishing fuel accountability and optimization for a vehicle. The apparatus can include a fuel tank containing hydrocarbon fuels operably engaged to a fuel sensor, an engine positioned inside the vehicle adapted to power the vehicle which is operable with the hydrocarbon fuels supplied from the fuel tank into the engine through a fuel supply line directed from the fuel tank to the engine, a flow meter operably engaged to the fuel supply line which measures the flow rate of the hydrocarbon fuels moving through the fuel supply line from the fuel tank into the engine, a communication network for transmitting data interfacing with the first flow meter, a computer defining a server having a memory and interfacing with the communication network to communicate with the first flow meter and adapted to interface with a user, and a computer program stored in the memory of the computer with instructions.
