What type of engine oil is suitable for the second maintenance of the Tiguan L?
1 Answers
Tiguan L's second maintenance is more suitable with full synthetic engine oil. Full synthetic oil provides better lubrication effects, offering functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, etc. The base oil is the main component of lubricating oil, determining its fundamental properties. The functions of automotive engine oil are as follows: 1. Sealing and leak prevention: Engine oil can form a sealing ring between the piston ring and the piston, reducing gas leakage and preventing external contaminants from entering. 2. Rust and corrosion protection: Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases.
