Fluid and Lubricant Recommendations

UsageFluid/Lubricant
Engine OilThe engine requires engine oil approved to the dexos™ specification. Oils meeting this specification can be identified with the dexos™ certification mark. Look for and use only an engine oil that displays the dexos™ certification mark of the proper viscosity grade. SAE 5W-30 GM P/N 19293000 (Canadian P/N 19286321) is the best viscosity grade for the vehicle. Do not use other viscosity oils.

GM Oil Life System Resetting

When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message or light will come on. Change the engine oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset.

If the system is ever reset accidentally, change the engine oil at 3, 000 miles (5 000 km) since last oil change.

How to Reset the Engine Oil Life System

Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system

  1. Turn the ignition to ON/RUN with the engine off.
  2. Press the DIC menu button on the turn signal lever to scroll through the menu items on the DIC screen.
  3. Press the set button to clear the CHANGE ENGINE OIL SOON message and/or restore the REMAINING OIL LIFE 100% message.
  4. Turn the ignition to LOCK/OFF.

The system is reset when the CHANGE ENGINE OIL SOON message is off and the REMAINING OIL LIFE 100% message is displayed.

If the CHANGE ENGINE OIL message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
