Section 5 Service and Appearance Care

Notice:Use only engine oil identied as
meeting GM Standard GM6094M and showing
the American Petroleum Institute Certied
For Gasoline Engines starburst symbol.
Failure to use the recommended oil can
result in engine damage not covered by your
warranty.
GM Goodwrench
®oil meets all the requirements
for your vehicle.
If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide
easier cold starting and better protection for
the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet
GM Standard GM6094M are all you need for
good performance and engine protection.
When to Change Engine Oil
If any one of these is true for you, use the
short trip/city maintenance schedule:
•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, taxi, 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, change the 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 (12 500 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.

{CAUTION:
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 would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and 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 extra inhibitors and/or
additives in your vehicle’s cooling system,
you could damage your vehicle. Use only the
proper mixture of the engine coolant listed
in this manual for the cooling system.

Lubricants on page 382for more information.
