Chevy Service Guide
Chevy Maintenance Schedule by Mileage
What your Chevrolet needs and when, from oil changes and tire rotations to spark plugs and transmission fluid. A plain-English guide from the Certified Service team at Tim Lally Chevrolet.
The short answer
Most Chevrolets need an oil change when the Oil Life System calls for it, usually around 7,500 miles and no later than 12 months. Rotate tires every 7,500 miles. Bigger items follow later: brake fluid around 45,000 miles, spark plugs around 97,500 miles and coolant around 150,000 miles or 5 years. Your owner's manual has the exact schedule for your model and engine.
How It Works
How the Chevy Oil Life System sets your schedule
Modern Chevrolets do not use a fixed 3,000-mile oil change. The Oil Life System tracks engine revolutions, temperature and driving conditions, then tells you when the oil is due. Short trips, cold starts, towing and stop-and-go traffic all shorten the interval.
For most drivers the reminder lands around 7,500 miles. Even if the system has not asked for a change, plan on one at least once every 12 months, because oil breaks down with time as well as miles. Each visit is a good time to rotate the tires and run a multi-point inspection. Book your next Chevy oil change with our Certified Service team.

Chevy maintenance schedule at a glance
| Mileage | What to do |
|---|---|
| Every 7,500 mi | Oil and filter change when the Oil Life System calls for it (at least every 12 months), tire rotation, multi-point inspection |
| Every 22,500 mi | Replace the cabin air filter (sooner in dusty or high-pollen conditions) |
| Every 45,000 mi | Replace the engine air filter and brake fluid; severe-service transmission fluid change if you tow or drive in heavy traffic |
| Every 97,500 mi | Replace spark plugs; change automatic transmission fluid under normal driving; inspect drive belts |
| 150,000 mi / 5 years | First engine coolant (DEX-COOL) drain and fill, whichever comes first |
| Every visit | Check tire pressure and tread, brakes, wipers, lights, battery and fluid levels |
Intervals are general Chevrolet guidance and vary by model, engine and driving conditions. Your owner's manual is the final word for your vehicle, and our service advisors can pull the exact schedule for your VIN.
Severe Service
When to follow the severe-service schedule
Chevrolet lists a shorter schedule for vehicles that work harder than average. In Northeast Ohio, a lot of drivers fall into that group without realizing it. Follow the severe-service intervals if you regularly:
Drive in tough conditions
Make lots of short trips in freezing weather, sit in stop-and-go traffic, idle for long periods, or drive on salted, dusty or gravel roads.
Work the vehicle hard
Tow a trailer, carry heavy loads, use a plow, or drive for commercial use such as delivery or ride share.
For severe service, the biggest change is the automatic transmission fluid, which moves from about 97,500 miles to about 45,000 miles. Tire rotations, filters and brakes also need closer attention. Salt and cold are hard on brakes, batteries and tires, so we check them at every visit.
Owner Questions
Chevy maintenance schedule: FAQ
How often should I change the oil in my Chevy?
Change the oil when the Oil Life System tells you to, which is usually around 7,500 miles, and at least once every 12 months.
Short trips, cold weather and towing can bring the reminder up sooner. Follow the system rather than a fixed mileage.
What does the Chevy Oil Life System do?
It calculates when your oil is due based on engine revolutions, temperature and driving conditions.
When the oil life reaches a low percentage, a reminder appears on the dash. Reset it after each oil change so the next reminder is accurate.
How often should Chevy tires be rotated?
Rotate your tires every 7,500 miles, which usually lines up with each oil change.
Regular rotation evens out tread wear, extends tire life and keeps handling predictable in rain and snow.
When does a Chevy need new spark plugs?
Most Chevy engines are due for spark plugs around 97,500 miles.
Some engines differ, so check your owner's manual or ask a service advisor to look up the interval for your VIN.
How often should I change the transmission fluid?
Under normal driving, change automatic transmission fluid around 97,500 miles; under severe service, around 45,000 miles.
Towing, heavy loads and stop-and-go traffic all count as severe service, so many truck owners should use the shorter interval.
Does dealer maintenance keep my Chevy warranty valid?
Following the factory schedule and keeping records protects your warranty, and dealer service keeps those records on file for you.
