How many kilometers should a car generally go before changing the oil?

Under normal circumstances, the oil change interval is between 5,000-10,000 kilometers or every six months to a year. The following is an introduction to the functions of engine oil: 1. Lubrication: Engine oil forms a lubricating film between the piston and cylinder, thereby reducing friction. 2. Sealing: The oil film formed by engine oil can prevent gas and oil leakage. 3. Cleaning: Engine oil can circulate and carry carbon deposits, sludge, and wear particles from engine components back to the oil pan. 4. Rust and corrosion prevention: The oil film on the surface of components prevents contact with moisture and air, achieving rust and corrosion prevention.
As an ordinary car owner, I'd like to share insights about the frequently discussed oil change mileage. In most cases, it's recommended to change engine oil every 5,000 to 10,000 kilometers, depending on your vehicle's age and driving habits. I drive a family sedan - when new, I followed the manual's suggestion of changing oil every 10,000 km. But now that it's over 100,000 km, I've moved it up to 7,500 km intervals because older engines are prone to wear. For SUVs or vehicles frequently driven on rough terrain, oil deteriorates faster and may require changes every 5,000 km. Always check the dipstick - if the oil appears black or contains debris, address it promptly. City drivers facing constant stop-and-go traffic should be especially vigilant as frequent short trips accelerate oil degradation. A friend of mine learned this the hard way with costly engine repairs. Remember: regular maintenance prevents minor issues from becoming major expenses - it's both economical and safer. Don't procrastinate on oil changes.
