The lubrication system of a car is the core of ensuring the smooth operation of the engine. It not only reduces friction and wear but also helps in cooling and cleaning the engine. However, over time, the lubrication system faces various challenges, including oil aging, contamination, and the accumulation of deposits. These issues can not only reduce engine efficiency but also lead to costly repairs. Therefore, regular professional maintenance of the lubrication system is key to maintaining car performance and extending its service life.
