How many kilometers should a car drive before changing the engine oil?

[DiPeyton]

Engine oil is divided into 3 types: fully synthetic, semi-synthetic, and mineral oil. The number of kilometers a car should drive before changing the oil depends on the type of oil used. Generally, fully synthetic oil should be changed every 10,000 kilometers or once a year; semi-synthetic oil should be changed every 7,500 kilometers or every 7-8 months; and mineral oil should be changed every 5,000 kilometers or every 6 months. Below is an introduction to engine oil: 1. Engine oil, also known as engine lubricant, is hailed as the "blood" of a car. It plays a role in lubricating, cleaning, cooling, sealing, reducing friction, preventing rust, and preventing corrosion in the engine. 2. The engine is the heart of a car. Inside the engine, there are many metal surfaces that move against each other. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. Under such extreme conditions, only qualified lubricating oil can reduce the wear and tear of engine parts and extend their service life.
