Factory maintenance schedule OEM · verified
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the engine oil and filter every 7,500 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.
