Which Volkswagen CC models do not consume engine oil?
1 Answers
Volkswagen CC models equipped with the EA888 series engine do not consume engine oil. The following is a related introduction to engine oil consumption: 1. Defect in the cross-hatch design on the cylinder walls: The cross-hatch pattern can store a portion of engine oil, which lubricates the cylinder walls during high-speed operation to reduce wear. However, during low-speed operation, the stored oil in the cross-hatch pattern can be burned off. 2. Defect in the design of the oil separator: Oil vapor cannot be completely separated, and some of it will re-enter the combustion chamber and participate in combustion. This results in the phenomenon of engine oil consumption.
