Engine Oil
For diesel engine vehicles, see“Engine Oil”in the Duramax dieselsupplement.
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0288.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.
Checking Engine Oil
Check the engine oil level regularly,every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0283for 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 theoil level.
Follow these guidelines:
.To g e t a n a c c u r a t e r e a d i n g , p a r kthe vehicle on level ground.Check the engine oil level afterthe engine has been off for atleast two hours. Checking theengine oil level on steep gradesor too soon after engine shutoffcan result in incorrect readings.Accuracy improves when

checking a cold engine prior tostarting. Remove the dipstickand check the level.
.If unable to wait two hours, theengine must be off for at least15 minutes if the engine iswarm, or at least 30 minutes ifthe engine is not warm. Pull outthe dipstick, wipe it with a cleanpaper towel or cloth, then push itback in all the way. Remove itagain, keeping the tip down, andcheck the level.
When to Add Engine Oil
2.5L L4 Engine
3.6L V6 Engine
If the oil is below the cross-hatchedarea at the tip of the dipstick andthe engine has been off for at least15 minutes, add 1 L (1 qt) of therecommended oil and then recheckthe level. See“Selecting the RightEngine Oil”later in this section foran explanation of what kind of oil touse. For engine oil crankcasecapacity, seeCapacities andSpecifications0380.
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 you find that you
have an oil level above the
operating range, i.e., the engine
(Continued)
Caution (Continued)
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. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
SeeEngine Compartment Overview0283for the location of the engineoil fill cap.
Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.
Selecting the Right Engine Oil
Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.SeeRecommended Fluids andLubricants0375.

include engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. Forthe oil life system to work properly,the system must be reset every timethe oil is changed.
On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes on toindicate that an oil change isnecessary. SeeEngine OilMessages0134.Changetheoilassoon as possible within the next1000km (600mi). It is possible that,if driving under the best conditions,the oil life system might indicate thatan oil change is not necessary forup to a year. The engine oil andfilter must be changed at least onceayearand,atthistime,thesystemmust be reset. For vehicles withoutthe CHANGE ENGINE OIL SOONmessage, an oil change is neededwhen the OIL LIFE REMAININGpercentage is near 0%. Your dealerhas trained service people who willperform this work and reset the
system. It is also important to checkthe oil regularly over the course ofan oil drain interval and keep it atthe proper level.
If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. Always reset theengine oil life to 100% after every oilchange. It will not reset itself. Toreset the engine oil life system:
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.Ifthevehicledoes not have DIC buttons, thevehicle must be in P (Park) toaccess this display.
2. Press and holdVon the DIC,
or SET/CLR on the turn signallever if the vehicle does nothave DIC buttons, for severalseconds. The oil life willchange to 100%.
The oil life system can also be resetas follows:
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.
2. Fully press the acceleratorpedal slowly three times withinfive seconds.
If the display shows 100%, thesystem is reset.
If the vehicle has a CHANGEENGINE OIL SOON message and itcomes back on when the vehicle isstarted and/or the OIL LIFEREMAINING is near 0%, the engineoil life system has not been reset.Repeat the procedure.
