How Many Kilometers Should You Change Engine Oil for Car Maintenance?
2 Answers
How many kilometers you should change the engine oil for car maintenance depends on the type of oil used, as not all oils follow the same standard. Generally, conventional oil should be changed approximately every 5,000 kilometers; semi-synthetic oil, around 7,500 kilometers; and full-synthetic oil, about 10,000 kilometers. Engine oil, also known as motor lubricant, serves multiple functions such as lubrication, friction reduction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and cushioning shocks. 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 base oil's performance shortcomings, providing additional beneficial characteristics, making them a crucial part of the lubricant.
Having driven for over a decade, I've concluded that the oil change interval generally falls between 5,000 to 15,000 kilometers, depending on usage. I use full synthetic oil and change it every 10,000 kilometers. However, if there's frequent stop-and-go city driving or prolonged traffic during commutes, the oil gets dirty faster, so I change it around 8,000 kilometers. On highways where driving is smooth, oil degradation is slower, allowing for a slightly extended interval—but don’t push it too far. Always check if the oil level is normal; clear color is good. If it’s black or the oil pressure light comes on, address it immediately. Don’t just save money—regular maintenance can extend engine life by over a decade. Once, I delayed a change for over a year and ended up paying thousands in repairs. Now, I make it a habit to visit a reputable shop every six months or 10,000 kilometers, also checking brakes and tire pressure. Safety first—a well-maintained car means peace of mind.
