The Complete Car Maintenance Schedule: What to Do and When

Why Maintenance Schedules Matter

Skipping or delaying routine maintenance is one of the most expensive mistakes car owners make. A $50 oil change skipped can lead to a $4,000 engine repair. A missed brake inspection can become a $1,200 brake job — or worse, an accident.

The good news: modern cars are incredibly reliable when properly maintained. Follow this schedule and your vehicle will last well past 200,000 miles.

Every 3,000–5,000 Miles: Oil Change

Conventional oil: Every 3,000–5,000 miles

Synthetic oil: Every 7,500–10,000 miles (check your owner's manual)

Oil is your engine's lifeblood. It lubricates moving parts, reduces heat, and carries away contaminants. Old, dirty oil loses its ability to do all three.

Signs you're overdue: dark brown or black oil on the dipstick, engine running louder than usual, oil change light on.

Every 5,000–7,500 Miles: Tire Rotation

Rotating your tires ensures even wear across all four. Front tires wear faster than rear tires (especially on front-wheel-drive vehicles), so rotating them extends the life of your full set.

A full set of tires costs $400–$1,200. A rotation costs $20–$50. Do the math.

Every 15,000–30,000 Miles: Air Filter Replacement

Your engine air filter keeps dust and debris out of the engine. A clogged filter reduces fuel efficiency and performance.

Cabin air filters (which clean the air inside your car) should also be replaced every 15,000–25,000 miles — especially important if you have allergies.

Every 20,000–60,000 Miles: Brake Inspection

Brake pads typically last 20,000–60,000 miles depending on driving style. City driving wears them faster than highway driving.

Signs you need brake service: squealing or grinding when braking, longer stopping distances, brake pedal feels soft or spongy, car pulls to one side when braking.

Don't wait on brakes. This is a safety issue.

Every 30,000 Miles: Transmission Fluid

Transmission fluid lubricates the gears and keeps your transmission running smoothly. Neglecting it is one of the top causes of expensive transmission failures.

Automatic transmissions are especially sensitive to fluid quality. Check your owner's manual — some modern vehicles have "lifetime" fluid, but most benefit from a change every 30,000–60,000 miles.

Every 30,000–50,000 Miles: Coolant Flush

Coolant (antifreeze) prevents your engine from overheating in summer and freezing in winter. Over time it becomes acidic and loses effectiveness.

A coolant flush costs $100–$150. An overheated engine can cost $1,500–$5,000 to repair.

Every 60,000–100,000 Miles: Spark Plugs

Spark plugs ignite the fuel-air mixture in your engine. Worn plugs cause misfires, rough idling, poor fuel economy, and hard starts.

Modern iridium or platinum plugs last 60,000–100,000 miles. Older copper plugs need replacement every 30,000 miles.

Every 60,000–100,000 Miles: Timing Belt

Not all cars have timing belts (some use chains), but if yours does, this is the most critical maintenance item on this list. A broken timing belt can destroy your engine in seconds.

Check your owner's manual. If your car has a timing belt, replace it on schedule — no exceptions.

How to Stay on Top of It All

The hardest part of car maintenance isn't doing the work — it's remembering when everything is due. AutoTrack tracks your mileage and sends you reminders when each service item is coming up, so you never miss a maintenance interval.

Add your vehicle and current mileage, and AutoTrack will automatically set up your maintenance schedule based on your odometer reading.
