Does Volkswagen cars burn engine oil?

[LaTucker]

Volkswagen cars do burn engine oil. This happens because the gap between the piston rings and the cylinder block is too large, allowing engine oil to enter the combustion chamber and burn. Volkswagen designs its engines to reduce friction between the piston rings and the cylinder walls to protect the engine and extend its lifespan. This creates an oil film on the cylinder walls, some of which burns off with the high-temperature combustion gases. Here are the reasons for burning engine oil: 1. Domestic fuel (including gasoline and engine oil) tends to produce carbon deposits. 2. Carbon deposits cause the piston rings to stick, losing their oil-scraping function; the oil return holes get blocked, preventing the engine oil from returning to the crankcase normally. 3. Wear between the cylinder walls and pistons leads to excessive gaps. 4. Corrosion and aging of valve seals and crankshaft seals result in oil leakage.
