What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the starburst symbol.
This symbol indicates that the oil has been certified by
the American Petroleum Institute (API).
Do not use
any oil which does not carry this starburst symbol.
II If you choose to perform
the engine oil change
service yourself, be sure
the oil you use has
the starburst symbol on
the front of the oil
container.
If you have your
oil changed for you, be
sure the oil put into
your engine is American You
should also use the proper viscosity oil for your
vehicle, as shown in the viscosity chart.
SAE 1OW-30 is the viscosity grade recommended for
your vehicle. However, you can use SAE 5W-30
if
it’s going to be colder than 60°F (16°C) before your next
oil change. When it is very cold, colder than
0°F
(-18°C) you should use an SAE 5W-30 oil. These
numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity grade oils, such
as SAE 1OW-40 or SAE 20W-50 under any conditions.

When to Change Engine Oil (Vehicles
Without the
GM Oil Life SystemTM)
If any one of these is true for you, use the short trip/city
maintenance schedule:
e
e
e
e
Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier
on top
of your vehicle.
The vehicle is used for delivery service, police, tax1
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months - whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or 12 months - whichever
occurs first. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil
to
break down slower.
When to Change Engine Oil (Vehicles
With the
GM Oil Life SystemrM)
If so equipped, your vehicle has a computer system that
lets you know when to change the engine oil and
filter. This is based on engine revolutions and engine
temperature and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. An ENGINE
OIL CHANGE SOON message
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that,
if you are driving under the best conditions, the
oil life system may not indicate that an oil change
is necessary for over a year. However, your engine oil
and filter must be changed at least once a year and
at this time the system must be reset. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember
to reset the oil life system
whenever the oil is changed.
5-20

How to Reset the Oil Life System
The GM Oil Life SystemTM calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system
so it can
calculate when the next oil change is required.
If a
situation occurs where you change your oil prior to an
ENGINE
OIL CHANGE SOON message being
turned on, reset the system.
Always reset the engine oil life to
100% after every oil
change. It will not reset itself.
To reset the Oil Life
System, do the following:
1. Display OIL LIFE on the DIC.
2. Press and hold the RESET button for more than
five seconds. The oil life will change to
100%.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long. Clean
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 QW~ oil, be sure to drain all the oil from the
filter before disposal. Never dispose
of oil by putting it
~. -I.!.- -.--I --:I- ... :LC. ^^^_ --A ..._+_" _" ~ YOU1 SKII I ~IIU II~IIZY vvll11 auap a1 IU vvaLG1, VI u ywwu
in the trash, pouring it on the ground, into sewers, or
into streams or bodies of water. Instead, recycle it
by taking it to a place that collects used oil.
If you have
a problem properly disposing
of your used oil, ask
your dealer, a service station or a local recycling center
for help.
Supercharger Oil
Unless you are technically
qualified and have the
proper tools, you should let
your dealer or a qualified
service center perform
this maintenance.
When to Check
Check oil level every 30,000 miles (50 000 km) or every
36 months, whichever occurs first.

off can cause you or others to be burned. The
air cleaner not only cleans the air, it stops
flame if the engine backfires. If
it isn’t there
and the engine backfires, you could be burned.
Don’t drive with
it off, and be careful working
on the engine with the air cleaner/filter
off.
I
Notice: If the air cleanedfilter is off, a backfire can
cause a damaging engine fire.
And, dirt can
easily get into your engine, which will damage
it.
Always have the air cleaner/filter in place when
you’re driving.
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
9 In hilly or mountainous terrain.

If you do not use your vehicle under any of these
conditions, change the fluid and filter at
100,000 miles
(166 000 km).

Notice: When adding coolant, it is important that
you use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@
is added to
the system, premature engine, heater core or
radiator corrosion may result.
In addition, the engine
coolant will require change sooner
-- at 30,000 miles
(50,000 km) or 24 months, whichever occurs first.
Damage caused by the use
of coolant other
than DEX-COOL@ is not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half
DEX-COOL@ coolant which won’t damage
aluminum
parts. If you use this coolant mixture,
you don’t need to add anything else. Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system
is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others
could be burned. Use a
50/50 mixture of clean,
drinkable water and
DEX-@SOL@ esslani.
Notice:
If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture can freeze
and crack the engine, radiator, neater core ana
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice: If you use the proper coolant, you don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
