If the low oil level light appears on the instrument cluster, check the engine oil level right away. See Low Oil Level Light. Check the engine oil level regularly; this is just a reminder.
Checking Engine Oil
It is a good idea to check the engine oil level at each fuel fill. 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 this is not done, the oil dipstick might not show the actual level.
- Pull 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
If the oil is below the MIN (minimum) mark, add at least one quart/liter of the recommended oil. 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 upper mark that shows the proper operating range, the engine could be damaged.
See Engine Compartment Overview for the location of the engine oil fill cap.
Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.
What Kind of Engine Oil to Use
Look for three things:
| • | GM6094M |
| Use only an oil that meets GM Standard GM6094M. |
| • | SAE 5W-30 |
| SAE 5W-30 is best for the vehicle. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50. |
| • | American Petroleum Institute (API) starburst symbol |
| • | Oils meeting these requirements should have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API). |
Notice: Use only engine oil identified as meeting GM Standard GM6094M and showing the American Petroleum Institute Certified For Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold, where the temperature falls below -20°F (-29°C), use either an SAE 5W-30 synthetic oil or an SAE 0W-30 engine oil. Both provide easier cold starting for the engine at extremely low temperatures. Always use an oil that meets the required specification, GM6094M. See "What Kind of Engine Oil to Use" for more information.
Engine Oil Additives / Engine Oil Flushes
Do not add anything to the oil. The recommended oils with the starburst symbol that meet GM Standard GM6094M are all that is needed for good performance and engine protection.
Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.
