How Long Should You Wait to Change the Oil in a New Car?

New cars can have their oil changed after driving 3,000 to 5,000 kilometers. After purchasing a car, owners can consult the technicians at the 4S dealership to determine the recommended mileage for an oil change. It is important to perform the first maintenance on time—neither too early nor too late. New car engines are typically filled with initial break-in oil, which is specifically designed for use during the break-in period, so avoid performing the first maintenance prematurely. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in a base oil. It mainly contains anti-wear additives, detergents, dispersants, and viscosity index improvers for multi-grade oils. Engine oil is used to lubricate internal combustion engines. Its primary functions include reducing friction and wear on moving parts, removing sludge and varnish from the engine, neutralizing acids produced by fuel and lubricant oxidation, improving piston ring sealing, and cooling the engine by carrying heat away from moving components.
When I first got my new car, I was wondering when to change the oil. My experience is that the first service is best done around 1,000 kilometers, because metal debris from the engine break-in period can get into the oil, and not changing it early may lead to oil line blockages or part wear. After I drove 1,000 kilometers and had the oil changed at the 4S shop, I clearly felt the engine became quieter and smoother. Subsequent oil change intervals depend on the type of oil: mineral oil is recommended to be changed every 5,000 kilometers, while synthetic oil can be stretched to 8,000 to 12,000 kilometers, but if you drive aggressively or make frequent short trips, you should check it earlier. Remember, regular maintenance not only extends engine life but also avoids major repairs later, saving both money and hassle. In short, checking the owner's manual is the most reliable approach—don't wait until the oil warning light comes on.
I recommend performing the first oil change at 1,000 to 1,500 kilometers for new cars to ensure optimal protection. During the early engine break-in period, impurities are released, and the oil captures these particles to prevent internal component wear. Oil change intervals shouldn't solely rely on mileage—driving habits significantly influence degradation: highway cruising causes slower oil deterioration, while stop-and-go city driving accelerates it. Subsequent changes depend on oil quality; synthetic oils can last longer but shouldn't exceed the manual's recommended intervals. As an automotive enthusiast, I emphasize timely maintenance—neglect may lead to sludge buildup, damaging oil pumps or filters, ultimately costing more. Practically, combine seasonal checks of oil levels to prevent engine dry-running.
