How Often Should Engine Oil Be Changed for a New Car?
2 Answers
New cars should have their engine oil changed according to the following intervals: conventional oil every 5,000 kilometers; semi-synthetic oil every 7,500 kilometers; and full-synthetic oil every 10,000 kilometers. Here are some relevant details: 1. Engine oil, also known as motor lubricant, consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance, providing additional benefits. 2. Engine oil can be broadly categorized into three types: conventional oil, semi-synthetic oil, and full-synthetic oil. If the oil's effectiveness falls below the required standard, it can negatively impact the engine's normal operation and cause significant damage.
When I first bought my new car, I also pondered this. I remember the 4S store salesperson told me the first service must be done at 5,000 km, and after that, it depends on the oil you use. My own car now always uses full synthetic oil, and the manual says to change it every 10,000 km, but I usually go in at 8,000-9,000 km. If I'm often stuck in city traffic with stop-and-go driving, which puts more load on the engine, I'll change it 1,000 km earlier. Friends who often drive on highways on weekends can relax a bit—the oil doesn’t deplete as quickly. The key is to regularly check the dipstick; if the oil is black or the level is low, it’s time for a change—don’t just focus on the odometer.
