Car Maintenance Schedule by Mileage
Enter your current mileage and how you drive, and see exactly what's due now, what may already be overdue, and what's coming up — with a cost estimate for every item.

An estimate is only half the job. Hidden Mechanics connects you with trustworthy, home-based mechanics who charge less than a dealership — and it's completely free for customers to search.
What your car needs, and when
Almost every expensive car repair started life as a cheap piece of maintenance somebody skipped. A $150 transmission fluid change prevents a $3,000 rebuild. A $120 serpentine belt prevents being stranded when the alternator and water pump stop turning at the same time. The problem is that service schedules are buried in owner's manuals nobody reads, so this tool pulls the common ones into a single list based on the only number you actually need to know: your mileage.
The intervals that matter most
Oil and filter every 7,500 miles on synthetic, and tire rotation every 6,000, are the two that pay for themselves fastest — rotation alone can add 10,000 to 15,000 miles to a set of tires. From there the milestones cluster: filters and alignment in the 20,000–30,000 range, brakes and brake fluid around 40,000 to 45,000, then the big one at 60,000 where coolant, transmission fluid and the battery tend to come due together. Spark plugs and timing belts sit at 100,000, and on an interference engine a timing belt is genuinely non-negotiable — when it snaps it bends valves and can write off the engine.
Normal versus severe driving
Manufacturers publish two schedules, and most drivers qualify for the harsher one without realising it. Short trips under five miles, stop-and-go commuting, towing, dusty roads and extreme temperatures all count as severe service, and every interval shortens by roughly 30%. A five-mile commute in summer heat is harder on oil than a 200-mile highway run, because the engine never gets hot enough long enough to burn off the moisture and fuel that contaminate it.
Reading your results honestly
This tool can't see your service history, so it works from milestones rather than records. If something appears under “possibly overdue” and you had it done last month, tick it off and check it again at the next interval. Treat the output as a checklist to take to a mechanic, not a verdict. And always defer to your owner's manual for your specific vehicle — some engines use timing chains that aren't a scheduled item at all, and some modern cars have no serviceable fuel filter.
Want to know what a specific job on your list should cost? Run it through the car repair cost estimator. If a warning light has already appeared, the check engine code lookup will tell you what the code means before you book anything. Then find a mechanic near you — home-based mechanics typically charge well below dealership rates for exactly this kind of routine work.
Frequently asked questions
Full synthetic oil in a modern engine goes 7,500–10,000 miles between changes; conventional oil needs replacing closer to every 5,000. The old 3,000-mile rule dates from an era of conventional oil and looser engine tolerances, and following it now mostly benefits the shop selling the service. That said, if you do a lot of short trips under five miles, tow, or drive in extreme heat or cold, shorten the interval by around 30% — moisture and fuel don't get burnt off on short runs and they contaminate the oil.
The 60,000-mile milestone is usually the biggest one before 100,000. Typically it covers a coolant flush ($100–$220), automatic transmission fluid ($150–$400), battery replacement if it's original ($150–$380), plus the routine oil, filters and tire rotation. Depending on the vehicle it may also pick up the fuel filter and differential fluid. Budget $400–$900 all in at an independent shop — noticeably less than a dealership will quote for the same list.
Manufacturers define severe service more broadly than most drivers expect: regular trips under five miles, extended stop-and-go traffic, towing or carrying heavy loads, driving on dusty or gravel roads, and sustained extreme heat or cold. A short commute in a hot city counts. If any of that describes your driving, shorten every interval by about 30% — that's the adjustment this tool applies when you select severe conditions.
No, and it's one of the more expensive myths in car ownership. Transmission fluid degrades with heat regardless of what the marketing says, and a fluid change at $150–$400 is trivial next to a $2,000–$4,500 rebuild. Most independent transmission specialists recommend a change every 60,000 miles even on 'sealed for life' units. If your fluid is already dark and burnt-smelling at high mileage, get advice first — on a badly neglected transmission a sudden full flush can occasionally do more harm than good.
No. In the US, the Magnuson-Moss Warranty Act means a manufacturer cannot void your warranty simply because someone else did the maintenance. You need to have the scheduled work done on time, using parts and fluids that meet the manufacturer's specification, and you need to keep the receipts. Beyond that you're free to use any independent or home-based mechanic you like — which is usually where the savings are.
