What are the reasons for burning engine oil in cars and how to avoid it?

Valve oil seal: the valve is to prevent oil from leaking into the combustion chamber, but with the extension of service life, it will wear and age, making the valve seal poor and the oil easy to enter the combustion chamber.

Piston clearance: After long-term operation, there will be carbon deposition on the piston, and at the same time there will be some wear and tear. After a long time, the piston clearance becomes larger, and the oil can easily enter the combustion chamber. This is often said that the vehicle needs to be replaced with oil with higher viscosity after a long time of use.

Matters needing attention of automobile fuel

By improving the lubricating ability of engine oil and reducing friction resistance and internal friction, the engine power can be improved. This additive is obviously not suitable for vehicles burning engine oil.

Attaching soft metal or other special materials (such as early PTFE) to the friction surface instead of the original metal friction, on the one hand, enhances the sealing performance, on the other hand, protects the original friction surface metal. This additive can play a certain role in the early stage of engine oil combustion, but because of its granular and random oil flow, it is easy to block the oil circuit and filter element, causing greater failures.
