Downloaded from www.Manualslib.com manuals search engine 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.
If you change your own
oil, be
sure you use oil that
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 Petroleum
Institute certified for
gasoline engines.

You should also use the proper viscosity oil for your
vehicle, as shown in the following
chart:

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 1OW-30 is best 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’s very cold, you should use
SAE
5W-30. These numbers on an oil container show its
viscosity, or thickness.
Do not use other viscosity oils,
such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified 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 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 dealer is ready to
advise if
you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Indicator. This feature
will let
you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t dete.ct dust in the
oil. So, if you
drive in
a dusty area, be sure to change your oil
every
3,000 miles (5 000 krn) or sooner. Remember
to reset the Oil Life Indicator when the oil has been
changed. For more information, see “Oil Life Indicator”
in the Index.
