1993 BUICK PARK AVENUE oil

0 SAE low-30
As shown in this 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 OF (1 6 ” 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
low-40 or SAE 20W-50.

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. (See
“Change Oil Soon” in the Index.)
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. (See “Change

What to Do with Used Oil:
A CAUTION:
Used engine oil contains things that have cause
skin cancer in laboratory animals. 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
0"
Used oil can be a real threat to the environment. Don't
ever dispose of
it by 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.
I
Air Cleaner
The air cleaner is in the front right section of the engine
compartment. To check or replace the filter, undo the
wing screws and pull the air cleaner open. Replace the
air filter, close the cover and screw
in the wing screws.
ProCarManuals.com

Refer to the Maintenance Schedule to determine when
to replace the air filter.
See “Scheduled Maintenance Services’’ in the Index.
A CAUTION:
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.

Automatic Transaxle Fluid
When to Check and Change:
A good time to check your automatic transaxle fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check:
Because this operation can be a little difficult, you may
choose to have this done at a Buick 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.

fluid could come out and fall on hot engine parts,
starting a fire. Be sure to get an

2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the cross-hatched
area.
4. If the fluid level is where it should be, push the
dipstick back
in all the way.
How to Add Fluid:
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level
into the cross-hatched area on the dipstick, It
doesn’t take much fluid, generally less than a
pint. Don’t overfill. We recommend
you use only fluid
labeled DEXRONWIE, because
fluids with that label
are made especially for your automatic transaxle.
Damage caused by fluid other than DEXRONB-IIE is
not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back
in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34°F (-37 “C) .
0 Give boiling protection up to 262 F ( 128 ” C) .
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
ProCarManuals.com

What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM
Specification
1825-M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification
1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change. If you use these, you
don’t need
to add anything else.
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and a proper antifreeze.

Using Solvent-Type Cleaner on
Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean
off better with just
water and mild soap.
If you need to use it, then:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably
cheesecloth). Cleaning should start at
the outside of
the stain, “feathering” toward the center. Keep

to a clean section of the cloth,

help prevent a cleaning ring. (See the previous

Cleaning the Top of the Instrument

of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.

Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar
to the painted surface
of your car. Don’t use strong
soaps, chemicals, chrome polish, or other abrasive
cleaners on them because
you could damage this
coating. After rinsing thoroughly, a wax may be applied.
I NOTICE:
If you have aluminum wheels, don’t use an
automatic vehicle wash that has hard silicon
carbide cleaning brushes. These brushes can
take
off the protective coating.
White Sidewall Tires
Your Buick dealer has a GM White Sidewall Tire
Cleaner. You can use a stiff brush with
it.
Weatherstrips
These are places where glass or metal meets rubber.
Silicone grease there will make them last longer, seal
better, and not stick or squeak. Apply silicone grease
with a clean cloth at least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material to the parts repaired or
replaced to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents,
road oil and tar, tree sap, bird droppings, chemicals from
industrial chimneys, and other foreign matter can
damage your vehicle’s finish if they remain on painted
surfaces.
Use cleaners that are marked safe for painted
surfaces for these stains.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
