Engine Oil
It’s a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the oil must be warm and the vehicle must be on
level ground.
I Turn off the engine
and give the oil a few
minutes to drain back
into the oil pan. If you
don’t, the oil dipstick
might not show the
actual level.

Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping the tip lower.
When to Add Oil
If the oil is at or below the ADD line, then you’ll need to add some oil. But
you must use the right kind. This section explains what kind
of oil to use.
For crankcase capacity, see “Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the cross-hatched area that shows the pro\
per
operating range, your engine could be damaged.

put the level somewhere in the
proper operating
range. Push the
dipstick all the way
back in when you’re
through.
What Kind of Oil to Use
Beginning midyear 1993, oils of the proper quality for your vehicle will be
identified with this new “starburst” symbol. The “starburst” symbol
indicates that the oil has been certified by the American Petroleum Institute
(API), and
is preferred for use in your gasoline engine.
You should look for this on the front of the oil container, and use only oils
that display this new symbol.

the following chart:

ANY OTHER GRADE OIL NOT RECOMMENDED
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
As shown in the chart, SAE 5W-30 is best for your vehicle. However, you
can use
SAE low-30 if it’s going to be 0°F (-1 8°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:
6-11

Downloaded from www.Manualslib.com manuals search engine SHorSG
“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 GM dealer is ready to advise if you
think something should be added.

Downloaded from www.Manualslib.com manuals search engine 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 (I 6 km).
0 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.
0 Most trips are through dusty places.
0 The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, then you need to change your oil
andfilter 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 km) or
12 months - whichever comes first. Change the filter at the first oil change
and at every other oil change after that.
Four-wheel Drive Remote Oil Filter
If your vehicle has four-wheel drive, you will have a remote oil filter
located under the hood. It is mounted to the front left inner fender, behind
the headlights.
Engine Coolant Heater (Engine Block Heater)
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 with 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
a real 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.
