Engine oil should be changed between 5,000 to 10,000 kilometers. Engine oil, also known as lubricating oil, is the lifeblood of a car. Inside the engine, there are many metal surfaces that rub against each other. These components move at high speeds in harsh environments, with working temperatures reaching 400 to 600 degrees Celsius. Under such extreme conditions, lubricating oil reduces wear on engine parts and extends their service life. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, providing certain new characteristics, making them an essential part of lubricating oil.

I've been driving for nearly ten years, and changing engine oil depends on the situation. Conventional oil generally needs replacement every 5,000 to 8,000 kilometers. Since I mostly drive in the city with frequent traffic jams, causing more engine wear, I visit the repair shop every 5,000 kilometers. Modern high-end cars using full synthetic oil can last up to 10,000 or even 15,000 kilometers, as stated in the manual. Engine oil is like the lifeblood of a car; not changing it timely can lead to engine overheating and increased carbon buildup, resulting in frighteningly expensive repairs. Make it a habit to check the dipstick: pull it out to see the color—if it's too black or thick, change it immediately. Don't skimp on small expenses to avoid bigger troubles. Beginners are better off following the dealership's schedule, keeping regular maintenance records for peace of mind.

As a driver who frequently travels long distances, I have deep experience with oil change intervals. I generally change it every 7,500 kilometers, but road conditions make a big difference: if I drive mostly on highways, I can extend it to 10,000 kilometers, but if I'm on rough rural roads a lot, I change it earlier at around 6,000 kilometers. Oil choice is crucial—synthetic oil handles high temperatures better and lasts longer. Remember to replace the oil filter when changing the oil, otherwise, the new oil will get dirty quickly. Checking is simple: after parking and letting the engine cool, check the dipstick—clear oil means it's good. My car’s engine light reminds me, so don’t ignore it. Maintaining this habit reduces the risk of engine failure and keeps the car running smoother and safer. Don’t try to save money—delaying even once could damage the entire engine.

Having driven for over 20 years, the mileage intervals for oil changes have changed dramatically. In the past, it was strictly every 5,000 kilometers, but now with technological advancements and improved oil quality, synthetic oils have extended the interval to 8,000-12,000 kilometers. I make it a habit to check every 7,000 kilometers, and change it if the oil level is low or appears black. If you drive aggressively, it's better to change it earlier to protect the engine from wear. The manual is the authoritative reference—following it is always the right move. Don't forget regular maintenance paired with simple checks; it saves money and gives peace of mind.
