TROUBLESHOOTING DIESEL ENGINES
LIQUI MOLY Solutions: High Fuel Consumption
High fuel consumption is usually caused by a dirty Fuel System. (filters, 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 an inefficient combustion and loss of power. 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
Other possible causes:
1 - Dirty Air Intake System (EGR Valve)
2 - Wrong motor oil viscosity or Low quality motor oil
3 - Accumulated sludge in engine chamber / Old motor oil.
OIL CHANGE SERVICE REQUIRED: Professional Service
- Clean the motor oil system to remove accumulated sludge before adding fresh oil See
