Increased oil consumption, smoke formation (dove-grey smoke from the exhaust)
Increased oil consumption can have different reasons, but coked piston rings are often the cause. Rarely is it due to the dirty crankcase ventilation.
Reasons / Recommendations
The cause of piston ring coking (oil deposits in the piston grooves) is usually engine overheating. However, this can also occur during normal operation if the engine has been operated with low-quality fuel or oil for a long time. The deposits in the piston grooves impede the movement of the piston rings, which is why the seal in the cylinder-piston group, through which the oil drains, is damaged. The carbonized piston rings must be cleaned of deposits. The means suitable for this contain special substances that dissolve and loosen the slag deposits formed under high temperatures. The deposits must be removed from the cylinder-piston group.
Increased wear between the cylinder wall and the piston ring can impair the sealing of the cylinder-piston group, which can lead to increased oil consumption. The resulting wear can be eliminated with the Revitalizant®. The Revitalizant® compensates for wear in the cylinder-piston group, optimizes the air gaps, which in turn optimizes oil consumption.
Dirty crankcase ventilation.
If the crankcase ventilation system is not working properly, the pressure in the engine crankcase increases, which leads to excessive oil consumption. The crankcase ventilation must be cleaned.
This can be done by disassembling the engine or applying car care products. (by improving the flushing properties of the engine oil).
