Most carmaker schedules repeat every 30,000 miles, with small services in between. This is the common pattern for modern gas cars:
| Every | Service |
|---|---|
| 5,000–7,500 mi | Engine oil & filter · tire rotation · fluid-level and tire-pressure check |
| 15,000 mi | Brake inspection · wiper blades · battery test |
| 30,000 mi | Engine air filter · cabin air filter · fuel system inspection · coolant and transmission fluid check |
| 60,000 mi | Brake fluid flush · transmission fluid (many cars) · coolant (some cars) · belts & hoses inspection · battery likely due · tires often due |
| 90,000–100,000 mi | Spark plugs (iridium/platinum) · timing belt on cars that have one · suspension & steering inspection · hoses replacement |
Severe service (short trips, towing, dust, great heat) moves most of these sooner. Electric cars skip the engine items. They still need tires, brakes, cabin filter, and coolant on their own schedule.
A worked example
Odometer at 28,450 miles:
- Due now: you're inside the 30,000-mile window (±2,500 mi). That means engine air filter, cabin air filter, fuel system check, and a coolant and transmission fluid check. An oil change and rotation land here too, if the last one was near 22,500.
- Coming up: brake inspection at ~30,000, next oil and rotation around 35,000.
- Next milestone: the 60,000-mile service (brake fluid, transmission fluid, belts and hoses). It's about 31,550 miles away.
Maintenance schedule questions, answered
What is the 30 60 90 rule for cars?
It's the short way to say that carmakers group big services at 30,000, 60,000, and 90,000 miles. The 30k service is mostly filters and checks. 60k adds fluids: brake, transmission, and coolant. 90k brings spark plugs and timing parts. Small jobs like oil changes repeat in between.
What maintenance is needed at 30,000 miles?
The typical 30,000-mile service is an engine air filter, a cabin air filter, a fuel system check, and a check of coolant and transmission fluid. That's on top of the usual oil change, tire rotation, and brake check. It's most often the cheapest of the three big ones.
What maintenance should be done at 60,000 miles?
At 60,000 miles most schedules call for a brake fluid flush. Many cars also need transmission fluid, some need coolant, and belts and hoses get a check. Add the usual oil, rotation, and filters. Tires and the battery often wear out near here too. That's why 60k services feel costly.
What needs to be replaced at 100,000 miles?
Around 90,000–100,000 miles, change the spark plugs. Long-life iridium sets are rated for about this. Change the timing belt on engines that use one. It's a must-do, since a broken belt can wreck the engine. Add coolant hoses, and a hard look at suspension, struts, and engine mounts.
How often should tires be rotated?
Every 5,000–7,500 miles for most cars. That's the same interval as an oil change, so doing both at once is the easy habit. Rotation evens out front and rear wear, so all four tires age together. Skip it, and a set can lose thousands of miles of life.
Will you remember any of this at 34,000 miles?
No one does. That's the point of a log. SteerLog keeps each car's service history and reminds you by date and mileage. Its Pro schedule presets load this whole checklist per car. No account, no subscription, and the record is still yours in 15 years. See how SteerLog works.
