Does the Volkswagen Passat Burn Engine Oil?

[ORafael]

Passat may also experience engine oil burning. Here are three main ways engine oil is consumed: 1. The gap between the intake and exhaust valve stems and the valve guides. A small amount of oil must pass through the valve seals to prevent the valves from sticking in the valve guides. 2. The gap between the pistons and the cylinder walls. The piston rings carry residual lubricating oil film on the cylinder walls into the combustion chamber during the upward stroke. 3. Mist-like oil particles enter the combustion chamber through the crankcase forced ventilation system. 4. Additional information: Engine oil consumption occurs as long as the engine is running; burning engine oil is a common phenomenon.
