As in the chart shown previously, SAE 5W
-
30 is best for
your vehicle. However, you can use SAE 10W
-
30 if it’s
going to be 0
_F (
-
18
_C) or above. 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
R
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 0W
-
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. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the GM Oil Life System
t will
indicate that a change is necessary. The mileage between
oil and filter changes will vary depending on how you
drive your vehicle
--
usually between 3,000 miles
(5 000 km) and 10,000 miles (16 000 km) since your
last oil and filter change. Under severe conditions, the
system may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 10,000 miles
(16 000 km) or 12 months (whichever occurs first)
without an oil change.
The system won’t detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner. Remember to
reset the CHANGE ENGINE OIL message whenever
the oil is changed.
