How often does a car engine need servicing?
You should change the oil every 3000-5000 Km. Rotate the tires every 5000Km. most major services run every 30,000 Km like at 30, 60, and 90 thousand Km which usually includes changing your filters, oil, air, fuel, etc. also tune ups can be included in majors, fluid flushes may be done, belts and hoses might be replaced. There are also lesser services in between that are done every 15,000 km. Every vehicle is different so please refer the owner’s manual of your car and it will tell you specifically what needs to be done and when.
