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 down, and check the level.
When to Add Engine Oil
If the oil is at or below the L (low) mark, then you’ll
need to add at least one quart
of oil. But you must use
the right kind. This part explains what kind
of oil to use.
For crankcase capacity, see “Capacities and
Specifications” in the Index.
I NOTICE: I
I Don’t add too much oil. If your engine has so I:
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap is located in the rear of the
engine compartment.
Be sure to
fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back
in when you’re through.

Oils recommended for your vehicle can be identified
by looking for the "Starburst" symbol.
This symbol
indicates that the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does not carry this Starburst symbol.
If you change your own
oil, be sure you use oil that
has the Starburst symbol
on the front of the oil
container.
If you have your
oil changed for you, be sure
the oil put into
your engine
is American Petroleum
Institute certified for
gasoline engines.

Page 251 of 386

Downloaded from www.Manualslib.com manuals search engine As shown in the 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, 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 20W-50.
I 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@ 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 OW-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. Your dealer is ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as
frequent driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow
a trailer or use a carrier on top
of your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. 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
occurs first.

Page 252 of 386

Downloaded from www.Manualslib.com manuals search engine If none of them is true, use the long triphighway
maintenance schedule. Change oil and filter every
7,500 miles (12 500 km) or 7.5 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
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.
Air Cleaner
Operating the engine with the air cleaner off can
cause you
or others to be burned. The air cleaner
not only cleans the air, it stops flame if the engine

backfires. If it isn't there, and the engine
backfires, you could be burned. Don't drive with
it off, and be careful working on the engine with
the
air cleaner off.
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.
Air Filter Replacement
To check or replace the filter:
1
1. Remove the screws on the cover.
2. Lift the cover up.

3. Pull out the filter and replace it.
4. Replace the cover and the screws.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If
you do not use your vehicle under any of these
conditions, change the fluid and filter
every
100,000 miles (166 000 km).
See “Scheduled Maintenance Services” in the Index.

Downloaded from www.Manualslib.com manuals search engine How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet dealership Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading
if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above 90 "F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at
normal operating temperature, which is
180°F to
200°F (82°C to 93°C).
See "Checking Transmission
Fluid Hot" in the Index.
Checking Transmission Fluid Hot
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above
50°F (10°C). If it's colder than 50°F (lO°C), drive
the vehicle in
DRIVE (D) until the engine temperature
gage moves and then remains steady
for 10 minutes.
Then follow
the hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for
five minutes
if outside temperatures are 50°F (10 "C)
or more. If it's colder than 50°F (lO"C), you may have
to idle the engine longer. Should the fluid level be low during
a cold check, you must perform a hot check
before adding fluid. This will give you a more accurate
reading of the fluid level.
