If the oil pressure light and/or the Oil Pressure Low -- Stop Engine message on the Driver Information Center (DIC) appears on the instrument cluster, it means you need to check your engine oil level right away.
For more information, see "Oil Pressure Low -- Stop Engine" under DIC Warnings and Messages and Oil Pressure Light .
You should check your engine oil level regularly; this is an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview for the location of the engine oil dipstick.
- Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level.
- Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.
When to Add Engine Oil
3.6L V6 Engine
4.6L V8 Engine
If the oil is below the cross-hatched area at the tip of the dipstick, you will need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications .
Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged.
3.6L V6 Engine
4.6L V8 Engine
See Engine Compartment Overview for the location of the engine oil fill cap.
Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through.
What Kind of Engine Oil to Use
Look for two things:
| • | GM4718M |
| Your vehicle's engine requires a special oil meeting GM Standard GM4718M. Oils meeting this standard may be identified as synthetic. However, not all synthetic oils will meet this GM standard. You should look for and use only an oil that meets GM Standard GM4718M. |
Notice: Using oils that do not have the GM4718M Standard designation can cause engine damage not covered by the vehicle warranty.
| • | SAE 5W-30 |
| As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. |
| These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. |
Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).
You should look for this on the oil container, and use only those oils that are identified as meeting GM Standard GM4718M and have the starburst symbol on the front of the oil container.
Your vehicle's engine is filled at the factory with a Mobil 1® synthetic oil, which meets all requirements for your vehicle.
Substitute Engine Oil: When adding oil to maintain engine oil level, oil meeting GM Standard GM4718M may not be available. You can add substitute oil designated SAE 5W-30 with the starburst symbol at all temperatures. Substitute oil not meeting GM Standard GM4718M should not be used for an oil change.
Engine Oil Additives
Do not add anything to your oil. The recommended oils with the starburst symbol that meet GM Standard GM4718M are all you will need for good performance and engine protection.
