What Kind of Oil to Use
Look for Three Things:
SG
“SG” must be on the oil container,
either by itself or combined with other
quality designations, such as
“SGICC,”
“SGICD,” “SF, SG, CC,”
etc. These letters show American
Petroleum Institute (API) levels of
1 quality.
If you use oils that don’t have the
“SG” designation, you can cause
engine damage not covered
by your
warranty.
’,”,, .
For best fuel economy and cold starting,
select the
lowest SAE viscosity grade oil ’;,:;:?,:!
for the expected temperature range,:?$’:&,:, 4 , ,,
IF NEITHER SAE 5W-30 NOR SAE 1OW-30
GRADE OILS ARE AVAILABLE, SAE 30 ’
GRADE MAY BE USED AT TEMPERATURES ’ ,
ABOVE 40 DEGREES F (4 DEGREES C). .,
ANY OTHER GRADE OIL NOT RECOMMENDED.
DO
NOT USE
SAE 1OW-40, SAE 20W-50 OR ’ i’
,,
SAE low-30
As shown in the viscosity 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, below
0°F
(-18”C), 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 1OW-40 or SAE 20W-50.
Energy Conserving 11
Oils with these words on the container
will help you save fuel.
This doughnut-shaped logo (symbol) is
used on most oil containers to help you select the correct oil.
You should look for this on the oil
container, and use
only those oils that
display the logo.
GM Goodwrench@ Oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your
Pontiac dealer is ready to advise if you
think something should be added.
