Car maintenance schedule: what to service and when

Most cars follow the same basic rhythm: an oil and filter change every 5,000 to 10,000 miles, a tire rotation about as often, filters and fluids at longer intervals, and a few bigger jobs like spark plugs and timing belts somewhere past 60,000 miles. The exact numbers depend on your engine and how you drive, and your owner's manual is always the final word.

This guide lays out typical intervals in one table, explains when the tougher "severe service" schedule applies, covers how EVs and hybrids differ, and shows you how to keep records that protect both your warranty and your resale value.

Typical maintenance intervals by mileage

Use this table to plan and budget, not to override your car's own schedule. Intervals are for normal driving. Where both miles and months are listed, whichever comes first is the one that counts.

Service	Typical interval	Notes
Engine oil and filter	5,000–10,000 miles or 6–12 months	Follow the oil-life monitor if you have one. Older engines and conventional oil often need 3,000–5,000 miles.
Tire rotation	5,000–7,500 miles	Easy to pair with every oil change. Evens out wear and extends tire life.
Engine air filter	15,000–30,000 miles	Check it at each oil change if you drive on dusty or gravel roads.
Cabin air filter	15,000–25,000 miles or yearly	A clogged one causes weak airflow, window fogging and musty smells.
Brake inspection	Every 10,000–12,000 miles or yearly	Pads commonly last 30,000–70,000 miles, depending on driving style and vehicle.
Brake fluid	Every 2–3 years	Fluid absorbs moisture over time, so this one is time-based, not mileage-based.
Coolant	30,000–60,000 miles (older types); 100,000 miles or 10 years (long-life)	Never open a radiator or reservoir cap on a hot engine.
Automatic transmission fluid	30,000–100,000 miles	Some makers call it "lifetime" fluid. Severe use usually means an earlier change.
Spark plugs	30,000 miles (copper); 60,000–120,000 miles (platinum or iridium)	Worn plugs cause misfires, rough idle and lower fuel economy.
Timing belt (if equipped)	60,000–105,000 miles or 7–10 years	Often replaced along with the water pump. Timing chains usually have no set interval.
12-volt battery test	Yearly from about year three	Most batteries last 3–5 years. Heat shortens battery life more than cold does.
Wiper blades	Every 6–12 months	Replace sooner if they streak, chatter or skip.

The timing belt deserves special attention. On many engines, a belt that snaps lets the pistons and valves collide, turning a few-hundred-dollar service into an engine replacement. If your car has a belt rather than a chain, find its interval in the manual and treat it as non-negotiable.

Normal vs severe service conditions

Most owner's manuals print two schedules. The normal schedule assumes steady, moderate driving. The severe schedule, sometimes called "special operating conditions," shortens many intervals, often cutting oil, filter and fluid service roughly in half.

You probably fall under severe service if you regularly:

• Make short trips of a few miles, especially in cold weather, so the engine rarely reaches full temperature
• Drive in heavy stop-and-go traffic or idle for long periods, as delivery and rideshare drivers often do
• Tow a trailer or carry heavy loads
• Drive on dusty, sandy, gravel or heavily salted roads
• Face extreme heat or cold, or climb steep grades often

Plenty of ordinary commuters fit at least one of these. Manufacturers define severe service differently, so read your manual's wording. If you're on the fence, choosing the shorter interval costs a little more each year and is cheap insurance against wear you can't see.

How EVs and hybrids differ

Electric vehicles

An EV drops a long list of items: no oil changes, spark plugs, timing belt or exhaust system, and no conventional transmission fluid. What remains still matters:

• Tires: EVs are heavy and deliver strong instant torque, so tires can wear faster. Rotate on schedule and keep an eye on alignment.
• Brakes: Regenerative braking means pads often last much longer, but calipers and rotors can corrode from light use. A yearly inspection matters, especially where roads are salted.
• Brake fluid and cabin filter: Same intervals as a gas car, roughly.
• Battery coolant: Many EVs use a liquid-cooled battery pack with long service intervals. Follow the manual exactly.
• 12-volt battery: Most EVs still have one, and it still wears out.

Hybrids

A hybrid keeps its gas engine, so it needs oil changes, spark plugs, coolant and filters like any car, although the engine may run fewer hours and the brakes usually last longer thanks to regeneration. Many hybrids also have a separate coolant loop for the power electronics and an air intake that cools the high-voltage battery, which can clog with dust or pet hair and needs occasional cleaning. Our EV ownership guide covers electric-specific care in more depth.

Monthly checks you can do yourself

Ten minutes a month in your driveway catches most problems before they turn into repairs. Do it with the engine cold and the car parked on level ground.

• Check tire pressure, including the spare, against the placard on the driver's door jamb
• Look over the tread for low depth, bulges, cuts or uneven wear
• Pull the dipstick and check the oil level and color
• Check coolant, brake fluid and washer fluid against the marks on each reservoir
• Test headlights, brake lights, turn signals and reverse lights
• Inspect wiper blades for cracks, tears or streaking
• Look under the car for fresh drips and note the color and location
• Check battery terminals for white or green corrosion
• Note any new warning lights, noises, smells or vibrations

A falling brake fluid level usually means worn pads or a leak, so have it checked rather than just topping it up. Our tires 101 guide explains how to measure tread and set pressure correctly. It's also worth running your VIN through our recall check a couple of times a year, since recall repairs are done free at a dealer.

Keep records: why it matters for warranty and resale

In the US, a manufacturer generally can't deny warranty coverage just because routine maintenance was done at an independent shop, done by you, or done with aftermarket parts, unless it can show that the part or the work caused the problem. The FTC explains these rights in its guide to auto warranties and service contracts. The catch is proof: if your engine fails under warranty, you may be asked to show that the scheduled oil changes actually happened.

For every service, keep:

• The date and odometer reading
• What was done, and the parts and fluids used, including the oil grade and specification
• The shop's name and the itemized receipt, or your parts receipts if you did it yourself

A folder in the glovebox works, but photos of each receipt in a cloud folder are easier to search and can't fade. Rules outside the US differ, so check your warranty booklet for what it requires.

Records pay off again when you sell. A complete, organized service history answers the first question every buyer asks and makes your car easier to trust than a similar one with no paperwork. See our guide to selling your car for the most money for more on presenting it well.

The bottom line

Car maintenance isn't complicated: change the oil on time, rotate the tires, replace filters and fluids on schedule, and never skip a timing belt. Decide honestly whether your driving counts as severe, do a quick check once a month, and keep every receipt. When a number here disagrees with your owner's manual, the manual wins.
