LIQUI MOLY  Solutions:   High Fuel Consumption

High fuel consumption is usually caused by a dirty Fuel System. (Injectors, valves and piston heads). Residue and deposit build-up in the fuel system will limit its capacity to deliver fuel to the engine and will cause loss of compression and an inefficient combustion. The engine will use more fuel for less mileage.

Use LIQUI MOLY (pour in fuel tank) treatments to clean and maintain the Fuel System. Always mix in to a full fuel tank
