⚑ QUICK DIY TIPS FOR THE 2020 GMC TERRAIN
  • Torque your drain plug to 25 Nm (18 ft-lbs) to avoid leaks or stripped threads.
  • Using the OEM filter (ACDelco PF2264G) is recommended for warranty compliance.
  • Always use 5W-30 Full Synthetic as specified by GMC — using the wrong viscosity can void your powertrain warranty.
  • Check the maintenance schedule below for your next service interval.
