RenaultKoregaThe maintenance cost for 20,000 kilometers is about 600Yuanabout. Korejia's 20,000-kilometer maintenance program includes replacement of engine oil, engine filter, air filter element and air conditioning filter element. The 20,000-kilometer maintenance of the Korega requires changing the engine oil. Engine oil is also called lubricating oil. If the engine is compared to the heart of a car, then the engine oil is the blood of the car. Its functions are as follows:

1. Lubrication and anti-friction: When the car starts, there is rapid relative friction between the piston and the cylinder, between the main shaft and the bearing bush, the timing gear, etc. One of the major functions of the engine oil is to pass the friction of the parts. An oil film is formed between the surfaces, and the oil film will separate the surfaces of the two friction parts, thereby reducing wear.

2. Cleaning: Another function of engine oil is to bring carbon deposits, sludge, metal wear particles and other dirt on engine parts back to the oil pan through circulating flow to achieve a cleaning effect.

3. Sealing and anti-leakage: Engine oil can also form an oil film between parts with relative motion to improve their sealing and help prevent air or oil leakage.
