Is it okay to drive 15,000 kilometers with full synthetic oil?
2 Answers
It should be fine to drive 15,000 kilometers with full synthetic oil. Full synthetic oil should be changed every 6-9 months or every 10,000-15,000 kilometers. Full synthetic oil: Full synthetic oil is of higher quality, and its use will result in noticeable improvements in the following aspects: smoother cold starts, better fuel efficiency, longer oil change intervals (approximately 1.5 times or more compared to conventional oil), extended engine lifespan, reduced maintenance frequency, and cleaner engine cylinders due to superior detergency. Semi-synthetic oil: Semi-synthetic oil is made using semi-synthetic base oil, which is lubricant formulated from Group III base oils. It is a product refined from mineral oil through hydro-cracking technology and consists of a 4:6 blend of mineral oil and full synthetic oil. Semi-synthetic oil's purity is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil.
Using full synthetic oil for 15,000 kilometers is generally fine in most cases. I've driven several cars, and full synthetic oil is of high quality with a long lifespan. Manufacturers typically recommend changing it every 10,000 to 15,000 kilometers, but it depends on the actual condition. For example, with my own car, I regularly check the dipstick. If the oil isn't too dark, the viscosity is still good, and the lubrication hasn't noticeably degraded, it means it's still usable. However, 15,000 kilometers is already the upper limit. By this point, impurities in the oil may have accumulated, the filtration may not be as efficient, and the risk of engine component wear increases. So, I recommend you go to the shop for an oil change as soon as possible—don't delay too long. Also, check your vehicle's manual, as different models have different oil change intervals. Safety comes first, and regular maintenance helps your car last longer.
