How Often Should the First Oil Change Be Done for a New Car?
2 Answers
For a new car, the first oil change should be done at 2,000 kilometers, followed by regular maintenance every 5,000 kilometers. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in a base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. The main functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine, neutralize acids produced by fuel and lubricant oxidation (detergents), improve the sealing of piston rings, and cool the engine by carrying away heat from moving parts.
When I first bought my new car, a friend reminded me to pay attention to the timing of the first oil change. I remember the manual stating that the initial oil change should be done at 5,000 kilometers or 6 months, as the new engine accumulates metal shavings and impurities during the break-in period. Failing to clean them promptly can accelerate wear. With my first car, I waited until 10,000 kilometers to change the oil, and by then, the oil had turned black, and the engine developed slight abnormal noises. The mechanic said there were increased signs of wear and recommended a deep cleaning, costing me an extra few hundred dollars. Since then, I've strictly followed the manufacturer's recommendations—being a little early doesn't hurt. New car owners should never assume that fresh oil in a new car means they can delay maintenance. Protecting the engine saves money and hassle in the long run.
