30,000 Mile Service

On older vehicles, the 30,000 mile service is commonly the first major service. However, on many newer vehicles with extended life fluids and spark plugs, this service can be an intermediate service, similar to a 15,000 mile service.

What to Expect

  • In addition to all that is performed at the 15,000 service, the 30,000 mile service is where you may start seeing some of the fluids replaced, such as the brake fluid, engine coolant, and transmission fluid. It can also include replacement of the spark plugs, air filter, and fuel filter.
  • A more comprehensive checklist of inspections may also be included. Each shop and vehicle manufacturer may vary the actions performed, so be sure to consult the maintenance schedule in your owners manual.
  • If this service is performed at the dealership, they should also take care of any necessary recalls. To check for recalls, click here.
