100,000 Mile Service

The 100,000 mile service is a minor service. Your next service will be the 105,000 mile service. At this time, some vehicles will require a timing belt, so be prepared for an expensive service next time in the shop.

What to Expect

  • This service generally involves an oil and filter change, tire rotation, and safety inspection
  • While changing the oil, the mechanic should perform a visual inspection of the brakes, belts, hoses. The mechanic should also look for any fluid leaks, listen for any abnormal noises, and pay attention to any irregularities in the operation of the vehicle.

Possible Repairs Needed at the 100,000 Mile Service

It's not uncommon to start seeing the wear and tear items like the drive belts and hoses, and motor mounts and suspension bushings starting to show signs of wear. Oil leaks may start to appear as well. Your next service may be quite expensive, so we recommend not putting off repairs until then if you wish to avoid a very large repair bill.


Service intervals may vary between auto manufacturers. Please consult your owners manual for service information related to your specific vehicle.
