2020 GMC Acadia Maintenance Schedule
Here are the 2020 GMC Acadia's service intervals, drawn from the manufacturer's published maintenance schedule — the key services, when each is due, and what each one does.

| Oil & Filter Change | 12,000 km / 7,500 miChange when the GM Oil Life System indicates (typically 12,000–16,000 km / 7,500–10,000 mi) or at least once a year. | 12 months |

Fluids & capacities
Capacities are "with filter" and vary by engine — check your GMC Acadia's engine option below.
| Engine oil | 0W-20 full synthetic, dexos1 — 5.0 qt (4.7 L) |
| Engine coolant | DEX-COOL (orange, extended life) |
| Spark plugs | Iridium, ~60,000 mi service life (turbo) |
| Automatic transmission fluid | DEXRON-ULV (8/10-speed) |
| Brake fluid | DOT 3 |
| Engine oil | 0W-20 full synthetic, dexos1 — 6.0 qt (5.7 L) |
| Engine coolant | DEX-COOL (orange, extended life) |
| Spark plugs | Iridium, ~97,500 mi service life |
| Automatic transmission fluid | DEXRON-ULV (8/10-speed) |
| Brake fluid | DOT 3 |
Confirm the grade and capacity against your owner's manual before servicing — figures can differ by trim, drivetrain and market.
What each service does
Oil & Filter Change
GM's Oil Life System calculates the interval from engine conditions rather than a fixed mileage, capped at one year.
Tire Rotation
Rotating tires with every oil change spreads tread wear evenly for longer tire life.
Engine Air Filter
GM inspects the air filter mid-life and replaces it around 72,000 km / 45,000 mi under normal driving.
Passenger Compartment (Cabin) Filter
Filters dust and pollen from the cabin air; GM lists replacement around 36,000 km / 22,500 mi.
Spark Plugs
GM's V8 plugs are rated for about 156,000 km / 97,500 mi. Worn plugs cause misfires and rough running.
Automatic Transmission Fluid
Clean fluid keeps the multi-speed automatic shifting smoothly; GM shortens the interval sharply for trucks that tow.
Engine Coolant (DEX-COOL)
GM's DEX-COOL is a long-life coolant rated for 5 years or 150,000 mi before its corrosion protection needs renewing.
Brake Fluid
Brake fluid absorbs moisture over time; GM calls for inspection rather than a set replacement mileage.
These intervals are drawn from the 2020 GMC Acadia's manufacturer maintenance schedule for normal service. Your vehicle's owner's manual remains the final authority, especially for "severe service" conditions like towing, short trips or dusty roads. BoxKitz links you straight to the manufacturer's manual and live recall data once you add the vehicle.
