How often does the car oil change?

It depends on the type of oil used by the vehicle.

There are usually three types of engine oils: fully synthetic, semi-synthetic and mineral engine oils.

Generally, synthetic engine oil should be replaced every 65,438+00,000 kilometers or 65,438+0 years.

Generally, semi-synthetic engine oil should be replaced every 7,500 kilometers or 7-8 months.

Generally, change mineral oil every 5,000 kilometers or 6 months.

If the oil is not changed for a long time, it will deteriorate and the lubrication effect will be reduced. When the engine is working, the internal parts of the engine are not lubricated, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.
