## Key Fluids & Replacement Intervals

**Oil & Oil Filter**  
Most modern vehicles: every 5,000-7,500 miles with conventional oil, or up to 10,000 miles with synthetic. Your owner's manual specifies the right interval and grade for your GMC.

**Transmission Fluid**  
Typically 60,000-100,000 miles; some newer vehicles need it less often. Check your manual.

**Coolant, Brake Fluid, Power Steering Fluid**  
Each has its own schedule-usually 30,000-100,000 miles depending on the fluid and your vehicle.

**Air Filter & Cabin Air Filter**  
Air filter: 15,000-30,000 miles. Cabin filter: 12,000-15,000 miles (more often in dusty conditions).
