Every manufacturer publishes a maintenance schedule, but few owners read it until something goes wrong. The schedule is not a sales pitch. It is the engineers telling you which parts wear out and roughly when. Following it is the cheapest way to keep a car reliable and to keep the warranty intact.
The rule that beats every table: your owner’s manual. The ranges below are typical for gas cars and help you sanity-check a quote, but intervals vary a lot between makes, engines and driving conditions.
Every month or every fill-up
These take a few minutes and catch most problems early:
- Tire pressure, cold, against the placard on the driver’s door jamb
- Engine oil level on the dipstick
- Lights, wipers and washer fluid
- Any new warning light, noise, smell or vibration
The typical schedule at a glance
| Item | Typical interval | Goes by |
|---|---|---|
| Engine oil and filter | 5,000 to 10,000 miles or 6 to 12 months | Miles or time |
| Tire rotation | 5,000 to 7,500 miles | Miles |
| Wiper blades | 6 to 12 months | Time |
| Cabin air filter | 15,000 to 30,000 miles or yearly | Miles or time |
| Engine air filter | 15,000 to 30,000 miles, sooner on dusty roads | Miles |
| Brake pads | Inspect at least yearly; replace when worn | Condition |
| Brake fluid | Every 2 to 3 years on many cars | Time |
| 12-volt battery | Test from about year 3; often lasts 3 to 5 years | Time |
| Spark plugs | About 30,000 miles for copper; 60,000 to 120,000 for platinum or iridium | Miles |
| Transmission fluid | 30,000 to 60,000 miles on many cars; some say lifetime | Miles |
| Engine coolant | Often first at 100,000 miles or 5 to 10 years on long-life coolant | Miles or time |
| Timing belt (if fitted) | Commonly 60,000 to 105,000 miles | Miles or time |
Around 30,000 miles
This is usually the first service that goes beyond oil and tires. Expect the engine air filter and cabin air filter, a careful brake inspection, and a look at belts, hoses, suspension and the exhaust. On some cars this is also the first transmission or brake fluid service.
Around 60,000 miles
Everything from the 30,000 service, plus the jobs that make this one more expensive: spark plugs on many engines, possibly transmission fluid, and on cars with a timing belt, a check of when it is due. Brake pads often need replacing somewhere in this range, depending on how and where you drive.
Around 90,000 to 100,000 miles
The big one. Timing belts, where fitted, are commonly due around here, and replacing the water pump at the same time often saves labor because the same parts come off. Long-life coolant usually gets its first change. If the spark plugs were not done at 60,000, they likely are now. Shock absorbers, engine mounts and drive belts start showing their age.
A timing belt is the one item you should never let slide. On many engines a broken belt lets the pistons hit the valves, which turns a few-hundred-dollar job into an engine rebuild.
Normal or severe schedule?
Most manuals list two sets of intervals. The severe one applies to short trips, heavy traffic, extreme temperatures, towing and dusty roads, which describes a lot of everyday driving. If that sounds like you, use the shorter intervals. For more on this, see how often to change your oil.
Some jobs go by the calendar
Brake fluid absorbs moisture from the air, rubber ages, batteries lose capacity, and coolant additives wear out whether or not the car moves. That is why a low-mileage car still needs servicing. If you drive less than about 8,000 miles a year, the time limits will usually decide your schedule, not the mileage.
Make the schedule run itself
The difficulty is not the list. It is remembering what was done, when, and at what mileage, across a dozen items with different intervals. Write each job down with the date and the odometer reading. Keep the receipts too: they also become your service history when you sell.
When you add a car to Badger, it builds a maintenance schedule for that type of car. Mark what was last done and when, and each item shows whether it is fine, coming up soon or overdue, by miles and by date.
Common questions
Do I have to service my car at the dealer to keep the warranty?
In the US, generally no. Under federal law a manufacturer cannot void a warranty just because maintenance was done elsewhere. What matters is that the work was done on time and you can prove it, so keep dated receipts.
What does a 30k, 60k or 90k service cost?
It varies widely by car and shop. Ask for an itemized quote and compare each line with your owner’s manual. Items that are not in the manual for that mileage are optional.
My car has a maintenance reminder on the dash. Is that enough?
It is a good prompt, but it usually covers only oil and a few basics. The full list of what is due is still in the manual.
