Chevrolet vehicles use the GM Oil Life System (OLS) — a percentage-based monitor that calculates oil life from driving conditions, not fixed mileage. When the OLS drops to 0%, oil and filter are due. The schedule below reflects GM's Normal Use intervals for everything else.
SEATS
Campaign #22V359000 · May 19, 2022
Issue: General Motors, LLC (GM) is recalling certain 2021 Chevrolet Malibu, 2022 Chevrolet Equinox, Blazer and Cadillac XT4 vehicles. The driver's seat cushion frame may have an improper weld in the power tilt-adjustment mechanism.
Risk: An improperly welded seat frame may not adequately restrain the driver in a crash, increasing their risk of injury.
Fix: Dealers will inspect the driver's seat and replace the cushion frame, as necessary, free of charge. Owner notification letters were mailed June 23, 2022. Owners may contact Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006. GM's number for this recall is N212356050.
Critical for safety and preventing major damage
Change oil when the Oil Life System reaches 0% or every 12 months — whichever comes first. dexos1-approved synthetic oil required on all gas engines since 2011.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate tires every 7,500 miles. Silverado 4x4 and Tahoe owners benefit from earlier rotations to even out drivetrain wear.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect brake pads, rotors, and parking brake at each tire rotation. Equinox and Malibu front pads typically last 40,000-50,000 miles.
Estimated cost — typical U.S. ranges
Dealer

Shop

DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
GM specifies brake fluid replacement based on contamination testing. Test every 30,000 miles; replace if moisture content exceeds 3% or fluid appears dark.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
GM long-life cellulose air filters are rated 45,000 miles. Direct-injection engines are sensitive to airflow restriction; inspect at every oil change.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Severe service (heavy towing, frequent stop-and-go, dusty conditions): replace every 45,000 miles. Normal service: 97,500 miles. Use Dexron-VI on 6L80/8L90 transmissions.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Silverado 4WD and Tahoe 4WD: replace transfer case fluid every 45,000 miles, sooner if towing or off-roading. Use GM Auto-Trak II fluid.
Estimated cost — typical U.S. ranges
Dealer
~$105–$140
Shop
~$75–$100
DIY
~$15–$40
AWD/4WD vehicles only. Easy drain-and-fill on most platforms.
GM iridium spark plugs are rated 100,000 miles on most LS and LT engines. The 5.3L V8 in Silverado 1500 commonly fouls plugs early under heavy idling.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
GM Dex-Cool (orange): first change at 150,000 miles or 5 years, then every 50,000 miles. Mixing with green coolant creates a sludge that destroys the cooling system.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Silverado and Tahoe: replace rear axle fluid every 50,000 miles, or 25,000 miles if towing. Limited-slip differentials require GM friction-modifier additive.
Estimated cost — typical U.S. ranges
Dealer
~$150–$195
Shop
~$105–$135
DIY
~$20–$50
Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.
Extends the life of your vehicle and improves comfort
Replace the cabin air filter every 22,500 miles. Silverado and Tahoe owners in dusty climates should replace earlier.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
