How Many Kilometers to Change Engine Oil?
2 Answers
For conventional engine oil, it is recommended to change it approximately every 5,000 kilometers. Semi-synthetic oil should be changed around every 7,500 kilometers, while full synthetic oil typically lasts about 10,000 kilometers before needing replacement. The oil change interval depends on factors such as the vehicle's operating environment, the driver's habits, and time duration. Engine oil serves multiple functions including lubrication, auxiliary cooling, sealing against leaks, rust and corrosion prevention, wear reduction, and cleaning of carbon deposits and sludge. There are three main types of engine oil: mineral oil, semi-synthetic oil, and full synthetic oil.
As a seasoned driver with over a decade of experience, I believe oil change intervals are actually quite flexible. Generally speaking, most vehicles recommend oil changes every 5,000 to 10,000 kilometers - this range mainly depends on your driving habits. For instance, if you frequently encounter city traffic jams or drive on dusty rural roads where the engine works harder, the oil degrades faster and may need replacement at around 6,000 km. Conversely, vehicles that mostly cruise on highways can typically stretch to about 8,000 km as the oil maintains better condition. Never rely solely on mileage - always combine it with checking the oil's color and viscosity. When the oil darkens, thickens, or develops a burnt smell, it's time for a change. I make it a habit to check the dipstick every three months to avoid procrastination and prevent engine damage that could shorten its lifespan. While oil changes may seem trivial, doing them properly can extend your car's service life by several years, saving both money and headaches. This is especially crucial for used cars - don't penny-pinch at the risk of major consequences.
