What Causes Volkswagen Engines to Burn Oil?

[McLayla]

Volkswagen engines burn oil for the following reasons: 1. The fuel quality is poor, which easily leads to a large amount of carbon deposits forming in the combustion chamber. These deposits accelerate the wear between the piston and cylinder wall, causing excessive clearance and allowing oil to flow into the combustion chamber. 2. The valve seals and front/rear crankshaft seals age, leading to poor sealing and oil leakage. 3. The air filter and oil filter become clogged. If the air filter is blocked, airflow is restricted, pressure drops, and oil is sucked into the combustion chamber. 4. The throttle valve is dirty. There are many complex reasons why an engine burns oil, but this doesn't mean the engine has an 'incurable disease.' Many auto repair shops can fix this issue, provided the problem is addressed promptly. If the oil burning persists for a long time without repair, a major engine overhaul may be necessary.
