Engine Oil Guide
To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment:
- Use engine oil approved to the proper specification and of the proper viscosity grade.
- Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
- Change the engine oil at the appropriate time.
- Always dispose of engine oil properly. See “What to Do with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly, every 650 km (400 mi), especially prior to a long trip. The engine oil dipstick handle is a loop. See Engine Compartment Overview for the location.
Warning
The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC) message displays, check the oil level.
Follow these guidelines
- To get an accurate reading, park the vehicle on level ground. Check the engine oil level after the engine has been off for at least two hours. Checking the engine oil level on steep grades or too soon after engine shutoff can result in incorrect readings. Accuracy improves when checking a cold engine prior to starting.
Remove the dipstick and check the level. - If unable to wait two hours, the engine must be off for at least 15 minutes if the engine is warm, or at least 30 minutes if the engine is not warm. Pull out the dipstick, wipe it with a clean 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 cross-hatched area at the tip of the dipstick and the engine has been off for at least 15 minutes, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” later in this section for an explanation of what kind of oil to use.
Caution
Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If the oil level is above the operating range (i.e., 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. Drain the excess oil or limit driving of the vehicle, and seek a service professional to remove the excess oil.
Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil depends on both the proper oil specification and viscosity grade.
Specification
Ask for and use full synthetic engine oils that meet the dexos1 specification. Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com.
Caution
Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty.
Viscosity Grade
Use SAE 5W-30 viscosity grade engine oil.
When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See
“Specification” earlier in this section.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The recommended oils meeting the dexos1 specification 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.
What to Do with Used Oil
Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products.

Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer’s warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based
on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.
When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and, at this time, the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.
If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed.
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:
-
Place the vehicle in P (Park).
-
From the infotainment home screen, select Vehicle Status > Maintenance > Oil Life > Reset.
-
Follow the menu and select Reset on the display screen. Then select Reset to confirm the reset. The percentage will changeto 100%.
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
Automatic Transmission Fluid
It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealer and have it repaired as soon as possible.
Change the fluid at the intervals listed in Maintenance Schedule, and be sure to use the transmission fluid listed in Recommended Fluids and Lubricants.
Caution
Use of the incorrect automatic transmission fluid may damage the vehicle, and the damage may not be covered by the vehicle warranty. Always use the correct automatic transmission fluid.
If you need to check the transmission fluid level, take the vehicle to your dealer.
Engine Air Filter Life System
If equipped, this feature displays a Driver Information Center (DIC) message with the remaining air filter life and service timing schedule. Frequency of the service prompts depend on driving and environmental conditions.
When to Change Engine Air Filter
Change the engine air filter when the DIC message indicates to:
-
Change the air filter at the next oil change.
-
Replace the engine air filter at the earliest convenience.
If the DIC displays a message to check the engine air filter life system, see your dealer.
How to Reset the Engine Air Filter Life System
Reset the system after replacing the engine air filter. To reset:
-
Place the vehicle in P(Park).
-
From the infotainment home screen, select Vehicle Status > Maintenance Engine Air Filter Life.
-
Touch RESET to reset the filter life, then select RESET to confirm. The percentage will change to 100%.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview for location.
When to Inspect the Engine Air Cleaner/Filter
-
For intervals on changing and inspecting the engine air filter, see Maintenance Schedule.
-
