What are the oil change intervals for cars?

The oil change intervals for cars are as follows: 1. Basic mineral oil should be changed every 5,000 kilometers or 6 months; 2. Semi-synthetic oil should be changed every 7,500 kilometers or 6 months; 3. Full synthetic oil should be changed every 10,000 kilometers or 12 months; 4. Brake fluid should be changed every 40,000 kilometers or 2 years; 5. Transmission fluid should be changed every 60,000 to 80,000 kilometers; 6. Power steering fluid should be changed every 40,000 kilometers or 2 years. Transmission fluid helps keep the gear system clean and lubricates the transmission components to extend their lifespan. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Minimizing gas leakage and preventing contamination from external pollutants; 3. Protecting components from contact with water, air, and harmful acidic gases; 4. Cushioning the pressure rise in the engine cylinder ports; 5. Flushing away dirt generated on the surfaces of components.
I remember oil changes are quite crucial, and the interval usually depends on the type of car and the oil used. I used to drive an old car that required a mineral oil change every 3,000 miles, but now my new car’s manual suggests every 7,500 to 10,000 miles because synthetic oil lasts longer. If you frequently drive in congested urban areas or dusty environments, the oil gets dirty faster, so it’s advisable to shorten the interval to 5,000 miles. As a driver like me, I make it a habit to check the dipstick every six months—if the oil is too dark or the level is low, it’s time for a change. Saving a little money here could lead to costly engine repairs later. Paying attention to maintenance indicator lights or app reminders has saved me a lot of trouble, and the engine runs much smoother too.
