Increased oil consumption can occur for several reasons, including stuck piston rings wear on the cylinder-piston group, or more rarely, contamination of the crankcase ventilation system.
Reasons / Recommendations
- The stiffness in piston rings is usually caused by coked oil in the grooves of the piston, which is a result of engine overheating. However, sticking may occur even during regular operation if the engine has been operating on low-quality oil or fuel for a prolonged time. The build-up of carbon deposits decreases the mobility of piston rings, thus damaging the seal in the cylinder-piston group, which lets oil out. The coils must be cleaned with a decarbonizer containing a solvent and softening high-temperature lacquer deposits, then removed from the cylinder-piston group.
