NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
ccStarburst”
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 where the temperature falls below
-20°F
(-29”C),
consider using either an
SAE
5W-30
synthetic
oil
or
an
SAE
OW-30
oil.
Both
will
provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your Pontiac dealer is
ready
to
advise if you think something should be added.
When to Change Engine Oil
If
any
one of these
is
true for you, use the short tripkity
maintenance
schedule:
a
e
e
e
a
lvlost trips are less than
5
to
10
miles
(8
to
16
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).
Most trips are through dusty areas.
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, 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
(12
500
km)
or
12
months
--
whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
