TROUBLESHOOTING GASOLINE ENGINES
LIQUI MOLY Solutions: Exhaust Smoke
If exhaust smoke is white and dissipates fast, it can just be water vapour from condensation. However, If its excessive, it can indicate that coolant is seeping into the combustion chamber due to gasket failure, in which case it requires immediate attention by a professional Mechanic.
If Exhaust smoke is grey or bluish grey, it means that the engine is burning motor oil. When motor oil finds its way into the combustion chamber, either through dried valve seals or worn cylinder rings, it will burnt out producing a bluish grey smoke. If its excessive, the engine requires immediate attention by a professional Mechanic.
LIQUI MOLY (motor oil additives) can stop or reduce the oil from leaking into the combustion chamber by rejuvenating seals and improving lubrication of the piston rings to prevent oil getting by.
Using one of LIQUI MOLY's anti-friction and wear protection products, together with Motor Oil Saver, can also help in reducing motor oil consumption.
Other possible causes:
1 - Wrong motor oil viscosity or Low quality motor oil
2 - 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
