Car Maintenance Schedule by Mileage
Type your odometer reading and get a checklist: what's due around your mileage and what's coming next. Based on the common 30k/60k/90k service pattern — your owner's manual is the authority for your exact car. Runs in your browser; nothing is saved or sent.
SteerLog turns this checklist into reminders on your lock screen — by date and mileage, per car.

Most manufacturer schedules repeat on a 30,000-mile cycle, with small services in between. This is the common pattern for modern gasoline 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, extreme heat — moves most of these earlier. Electric cars skip the engine items but keep 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) — engine air filter, cabin air filter, fuel system inspection, coolant and transmission fluid check. An oil change and rotation land here too if the last one was around 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 — about 31,550 miles away.
Maintenance schedule questions, answered
What is the 30 60 90 rule for cars?
It's the shorthand for how manufacturer schedules cluster major services at 30,000, 60,000, and 90,000 miles. The 30k service centers on filters and inspections, 60k adds fluids — brake, transmission, coolant — and 90k brings spark plugs and timing components. Small services like oil changes repeat between milestones.
What maintenance is needed at 30,000 miles?
The typical 30,000-mile service: engine air filter, cabin air filter, a fuel system inspection, and a check of coolant and transmission fluid — on top of the regular oil change, tire rotation, and brake inspection. It's usually the cheapest of the three big milestones.
What maintenance should be done at 60,000 miles?
At 60,000 miles most schedules call for a brake fluid flush, transmission fluid service on many cars, coolant on some, and a belts-and-hoses inspection — plus the usual oil, rotation, and filters. Tires and the battery often reach the end of their life around here too, which is why 60k services feel expensive.
What needs to be replaced at 100,000 miles?
Around 90,000–100,000 miles: spark plugs (long-life iridium sets are rated for roughly this), the timing belt on engines that use one — a must-do, since failure can wreck the engine — plus 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 — conveniently, the same interval as an oil change, so pairing them is the easy habit. Rotation evens out front/rear wear so all four tires age together; skipping it can shave thousands of miles off a set's life.
Will you remember any of this at 34,000 miles?
Nobody does — that's the point of a log. SteerLog keeps every car's service history, reminds you by date and mileage, and its Pro schedule presets load this whole checklist per vehicle. No account, no subscription, and the record is still yours in 15 years. See how SteerLog works.
