(-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.
Engine Coolant Heater (Engine
Block Heater) (omoN)
An engine coolant heater can be a big
help if you have to
park outside in very

cold weather, 0°F (-18°C) or colder. If
your vehicle has this option, see
Engine
Coolant Heater
in the Index.
What to Do wifh Used Oil
Did you know that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer? Don’t let used oil stay on
your skin for very long. Clean your skin
and nails with soap and water, or a
good hand cleaner. Wash or properly
throw away clothing or rags containing
used engine oil.. (See the manufacturer’s
warnings about the use and disposal of
oil products.)
Used oil can be areal threat to the
environment. If you change your own
oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t
ever dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies of
water. Instead, recycle it by taking it to
a place that collects used oil. If you
have a problem properly disposing of
your used oil, ask your dealer, a service
station or a local recycling center for
help.
Air Cleaner
Refer to the Maintenance Schedule to
determine when to replace the air filter
and the crankcase ventilation filter.
See
Scheduled Maintenance Services i3
the
Index.
NOTICE:
If the air cleaner is off, a backfire
can cause a damaging engine fire.
And, dirt can easily get into your
engine, which will damage
it.
Always have the air cleaner in place
when you’re driving.
To Check or Replace the Air Filter:
1. Remove the four screws and pull off
the cover.

NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your
warranty.
Too much water in the
mix can freeze and crack the
engine, radiator, heater core and other parts.
Adding Coolant
To Check Coolant
When your engine is cold, the coolant
level should be at the
COLD mark or a
little higher. When your engine is warm,
the level should be up to the
HOT mark
or a little higher.

If this light comes on, it means you’re
low on engine coolant.
To Add Coolant
If you need more coolant, add the
proper mix
at the coolant recovery
tank.
If the coolant recovery tank is
completely empty, add coolant to the
radiator. (See
Engine Overheating in
the
Index.)
