How Do I Maintain a Car With Over 100,000 Miles?
Past 100,000 miles, keep oil changes on time, replace aging rubber parts and fluids, and inspect the suspension and cooling system every service.
Is a car with over 100,000 miles worth maintaining?
Yes. Most modern cars can run well past 200,000 miles with consistent maintenance, and maintaining a paid-off car usually costs less than replacing it.
What parts wear out after 100,000 miles?
Common wear items are hoses, belts, motor and transmission mounts, suspension bushings, shocks and struts, the water pump and the radiator. Rubber parts harden and crack with age and heat.
Should I use high-mileage oil?
High-mileage oil contains seal conditioners that can reduce small leaks and oil consumption. Use it only if it meets the viscosity and specification in your owner's manual.
Which fluids should I replace on a high-mileage car?
Replace coolant, brake fluid and transmission fluid at the manufacturer's intervals if they have not been done. Ask for an inspection first if transmission fluid has never been changed.
What warning signs mean I need service now?
Get the car checked for any new leak, overheating, a check engine light, rough shifting, clunks over bumps or a burning smell. Early repairs prevent bigger failures.
