Car maintenance checklist by mileage.
Use the odometer as the calendar. Start with the 30k, 60k, 90k, and 100k checkpoints, then let the planner turn the general intervals into dates for your car.

This page starts at 75,000 miles as an example. Change the odometer to your car and rebuild.

The mileage milestones that matter.
30,000 miles
Routine oil and filters, tire rotation, brake inspection, and a first serious look at coolant and brake fluid. If the car has been used for short trips or towing, treat it as severe duty.
60,000 miles
A common transmission-fluid and spark-plug checkpoint, plus belts, hoses, and suspension. Some engines call for a timing belt here; many use a chain. Check the manual before buying parts.
90,000 miles
For engines with a timing belt, this is often the service window. Also expect another round of filters, fluids, and a brake and suspension inspection. A Pre-purchase inspection is a good idea if you are buying at this mileage.
100,000 miles
The car is not “done”; it is entering the phase where maintenance records matter. Prioritize brake lines, coolant, transmission service, suspension, battery health, and any oil leaks. Fix small leaks before they become expensive ones.
Do not use this page as a factory schedule. It is a planning layer; the owner’s manual and a mechanic’s inspection decide the actual work.
Good questions.
Short answers. The owner’s manual still wins.
What should be done at 30,000 miles?
A 30,000-mile checkpoint usually includes oil and filter, tire rotation, brake inspection, cabin and engine air filters, and a look at coolant and brake fluid. The exact list depends on the vehicle.
What should be done at 60,000 miles?
Besides routine oil, filters, tires, and brakes, 60,000 miles is a common point for transmission fluid, spark plugs, and a closer cooling-system inspection. Some vehicles use a timing belt or chain; check the manual.
What should be done at 90,000 miles?
The 90,000-mile range often brings timing-belt service on engines that use a belt, plus another round of fluids, filters, and suspension checks. Do not assume every car needs the same work.
What should be done at 100,000 miles?
At 100,000 miles, focus on fluids, belts, hoses, brake lines, suspension, battery health, and any deferred repairs. A mechanic’s inspection is more valuable than a generic list at this point.
Are these intervals exact?
No. They are general planning intervals. Severe duty, climate, and the owner’s manual can move them earlier or later.
