132 Instruments and Controls
When the ignition is on, the fuelgauge indicates about how muchfuel is left in the tank.
There is an arrow near the fuelgauge pointing to the side of thevehicle the fuel door is on.
When the indicator nears empty, thelow fuel light comes on. There still isalittlefuelleft,butthevehicleshould be refueled soon.
Here are four things that someowners ask about. None of theseshow a problem with the fuel gauge:
.At the service station, the fuelpump shuts off before the gaugereads full.
.It takes a little more or less fuelto fill up than the gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.
.The gauge moves a little whileturning a corner or speeding up.
.The gauge takes a few secondsto stabilize after the ignition isturned on, and goes back toempty when the ignition isturned off.
Engine Oil Pressure
Gauge
Metric
English
The engine oil pressure gaugeshows the engine oil pressurein kPa (kilopascals) or psi (poundsper square inch) when the engine isrunning.
Oil pressure can vary with enginespeed, outside temperature, coolanttemperature, and oil viscosity.

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 System0362.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.

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 andLubricants0462.
Specification
Ask for and use engine oils thatmeet the dexos1™specification.Engine oils that have beenapproved by GM as meeting thedexos1 specification are markedwith the dexos1 approved logo. Seewww.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 0W-20 viscosity grade forthe 5.3L and 6.2L V8 engines. UseSAE 5W-30 viscosity grade for the4.3L V6, and 6.0L V8 engines.
Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below✓29 °C(✓20 °F), an SAE 0W-30 oil may beused in the 4.3L or 6.0L engine. Anoil of this viscosity grade will provideeasier cold starting for the engine atextremely low temperatures.
When selecting an oil of theappropriate viscosity grade, it isrecommended to select an oil of thecorrect specification. See“Specification”earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. Therecommended oils meeting thedexos1 specification are all that isneeded for good performance andengine protection.
Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.
What to Do with Used Oil
Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.
Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in the
