(-18°C) or above. 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.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
“SH” or “SG” must be on the oil
container, either by itself or combined
with other quality designations, such
as “SH/CD,” “SH,SG,CD,”“SG/CD,”
etc. These letters show American
Petroleum Institute (API) levels of
quality.
SAE 5W-30
Energy Conserving I1
Oils with these words on the container
will help you save fuel.
These three things are usually included in
a doughnut shaped logo (symbol) on
most containers. If you cannot find
oils
with the “starburst” symbol, you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above.
NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API
SH or SG designation, you can
cause engine damage not covered
by your warranty.
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
Oldsmobile dealer is ready to advise if
you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles
(6 km)
.
It’s below freezing outside and most
trips are less than 10 miles (16 ltm).
The engine is at low speed most of the
time (as in door-to-door delivery, or in
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
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 comes
-first.
If none of them is true, change the oil
every
7,500 miles (12 500 lm) or 12
months -whichever comes first.
Change the filter at the first
oil change
and at every other oil change after that.
