When Should the Engine Oil Be Changed for a New Car?
2 Answers
For a new car, the engine oil can be changed every 5,000 kilometers, while synthetic oil can extend the interval to 8,000 to 10,000 kilometers. In terms of time, even if the car hasn't driven 5,000 kilometers within six months, the engine oil should still be considered for replacement. Engine oil plays multiple roles in the engine, including lubrication and wear reduction, aiding in cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the performance of the base oil, making them an essential part of the lubricant.
I've driven quite a few new cars, and engine oil changes are something you really can't take lightly. The first maintenance for a new car is especially critical because the engine produces a lot of metal debris during the break-in period. For the first oil change, I recommend doing it after driving 5,000 kilometers or 6 months. Back when I got my car, the dealership specifically called me twice to remind me. If you're driving long distances every day or frequently flooring the accelerator with aggressive driving, then you should check the oil condition as early as 3,000 kilometers. After the first maintenance, if you use full synthetic oil, many cars can go up to 10,000 kilometers before needing another change. But remember to pop the hood every week and check the dipstick—if the oil looks black or has thickened, go change it immediately. Don’t just rely on mileage; even if the car sits unused for three months, you should still change the oil, as prolonged exposure to air causes oxidation and degradation.
