🔧 Maintenance Schedule
Get the official OEM maintenance schedule — oil changes, filters, belts, spark plugs — by exact mileage interval.
Know exactly what your car needs, and when
Skip a timing belt and you could be looking at a $3,000 engine rebuild. Skip a transmission fluid service and you might be shopping for a new transmission in 40,000 miles. The manufacturer already published the exact schedule that keeps your car alive — this tool pulls it up for your specific vehicle, by VIN or Year/Make/Model, broken down by mileage interval. No more guessing which “30,000-mile service” items the dealer is actually supposed to do.
What the schedule covers
The OEM schedule isn’t a marketing document. It’s the list the automaker stands behind for warranty purposes and the one independent shops reference when they don’t want to overstep or miss something. Here’s what shows up:
Engine oil and filter
Interval, oil weight, filter part reference. Modern engines with 0W-20 synthetic often go 7,500–10,000 miles between changes, not 3,000 like the quick-lube sticker suggests.
Transmission fluid
The service most “lifetime fluid” claims quietly depend on you never reading. Automatics typically need a drain-and-fill by 60,000–100,000 miles. CVTs and DCTs have their own rules.
Timing belt or chain
If your engine has a belt (many Hondas, Subarus, older Volkswagens), replacement is not optional. Skip it and the valves hit the pistons. Chains are lifetime — but the tensioners aren’t.
Spark plugs
Iridium plugs last 100,000 miles. Copper plugs need replacing at 30,000. The schedule tells you which you have and when they’re due.
Coolant, brake fluid, differential
The fluids nobody thinks about until they fail expensively. Coolant every 60,000–100,000 miles. Brake fluid every 2–3 years. Differential and transfer case on their own intervals.
Filters and belts
Cabin air filter, engine air filter, fuel filter, serpentine belt, accessory belts. Small items, but the schedule tells you whether you’re due — and prevents upsells on items that aren’t.
Normal vs severe duty — which applies to you?
Every manufacturer publishes two schedules. Most drivers assume they’re on “normal” but actually meet the criteria for “severe” — and severe intervals are often 40–50% shorter. You fall into severe duty if any of these regularly describe your driving:
- Short trips under 10 miles, especially in cold weather (engine never fully warms up)
- Stop-and-go traffic in hot weather
- Dusty or off-road conditions
- Towing, hauling heavy loads, or carrying cargo on the roof regularly
- Extended idling — ride-share drivers, delivery, anyone sitting in traffic a lot
- Mountainous terrain with sustained grades
If two or more apply, run your schedule on the severe-duty intervals. Your transmission and engine will thank you twenty years from now.
What it saves you
Against the dealership
Walk in knowing exactly what’s due. When the service writer lists a $1,400 “60,000-mile inspection package,” you can compare it against the actual OEM schedule line by line and decline the items that are padding. Most dealer service menus bundle 3–4 legitimate items with 6–8 unnecessary ones.
Against neglect
The flip side. If you’re a DIY type or use an independent shop, the schedule catches the quiet items — differential fluid, coolant, brake fluid — that don’t throw warning lights but fail catastrophically if ignored. Most “sudden” major repairs on 150,000-mile cars trace back to a missed fluid service at 60,000.
How to use it effectively
- Look up your vehicle by VIN. VIN pulls your exact engine and drivetrain variant, which matters — the 2.0T and 3.0 V6 versions of the same car have completely different schedules.
- Check your current mileage. The schedule shows every interval. Find the one closest to where you are now and look at what’s due.
- Decide normal or severe duty. Be honest about your driving. Most urban and suburban drivers qualify for severe on at least one criterion.
- Print or screenshot it. Bring it to your next service appointment. “Here’s what the manufacturer says is due at this mileage” is the most productive sentence you can say at a service counter.
Common questions
Is this the same schedule the dealership uses?
Yes — the source is the official manufacturer maintenance schedule for your vehicle. The dealership has access to the same document. The difference is they may bundle items into “service packages” priced as a flat menu; the raw schedule tells you which items are actually required at that interval and which are upsells.
Does skipping a service void my warranty?
Missing a required scheduled service can void warranty coverage on related components, but only for the system that failed due to the missed service. The Magnuson-Moss Warranty Act protects you on everything else. Keep receipts for every service — dealer or independent — and you’re fine. The schedule is what they’ll check against.
My oil-life indicator says I have 40% left. Should I trust it or the mileage interval?
Both, with judgment. Oil-life monitors use real driving data (short trips, idle time, temperatures) and are usually reasonable. But if you’re past the mileage interval in the schedule and the monitor says you’re fine, change it anyway — monitors track oil breakdown, not additive depletion. The schedule has both in mind.
What if my car is older than the maintenance schedule covers?
Most schedules cover the first 100,000–150,000 miles explicitly, then say “repeat intervals from X miles.” Past that point, keep following the same intervals — an oil change at 180,000 miles works the same as at 80,000. Spark plugs, fluids, and filters don’t change their needs just because the car is older.
Can I use synthetic oil if the schedule lists conventional?
Yes, and most mechanics recommend it for older cars too. Synthetic handles heat better and lasts longer between changes. Just match the weight (5W-30, 0W-20, etc.) that the schedule specifies — that’s what matters for your engine’s tolerances. Don’t stretch change intervals past the schedule just because you upgraded to synthetic.
Why does my schedule look different from my friend’s same-model car?
Engine option, transmission type, drivetrain (FWD vs AWD), and model-year running changes all affect the schedule. A 2020 RAV4 Hybrid has a different schedule than a 2020 RAV4 gas. VIN lookup accounts for all of this — YMM alone might not capture the variant.
