fuel BUICK PARK AVENUE 1993 Owner's Manual

Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
Fuel that is more than 5% methanol is bad for
your vehicle. Don’t use it.
It can corrode metal
parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t be covered under your Warranty. And even at
5%
or less, there must be “cosolvents” and
corrosion preventers in this fuel to help avoid
Gasolines for Cleaner Air
Your use
of gasoline with detergent additives will help
prevent deposits from forming
in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines are now blended with materials called
oxygenates. General Motors recommends that you use
gasolines with these blending materials, such as MTBE and ethanol.
By doing
so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
Fuels in
Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled,
the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All
of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business
in the
country where you’ll be driving.

Filling Your Tank
The cap is behind a hinged door on the left side of your
vehicle.
A r PUTION:
Gasoline vapor is highly flammable. I? burns
violently, and that can cause very bad injuries.
Don't smoke if you're near gasoline or refueling
your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.

A CAUTION:
If you get gasoline on you and then something
ignites
it, YOU could be badly burned. Gasoline
can spray out on you if you open the fuel filler
cap too quickly. This spray can happen if your
tank is nearly full, and is more likely in hot
weather. Open the fuel filler cap slowly and wait I ’ for any “hlss” noise to stop. Then unscrew the
cap all the way. I
When you put the cap back on, turn it to the right until
you hear a clicking noise,

&
OTICE:
you neea a new cap, be sure IO get tne rlght
type. Your dealer can get one for you.
If you get
the wrong type,
it may not fit or have proper
venting, and your fuel tank and emissions
system might be damaged.
Checking Things Under the Hood
Hood Release
To open the hood, first pull
the handle inside the
vehicle.
It is located on the
lower left side
of the
instrument panel. When
you pull this handle, the
hood lock will open.

A CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
I underhood electric fan. I
A CAUTION:
1
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.
-- I
Before closing the hood, be sure all the filler caps are on
properly. Then just pull the hood down and close it
firmly.
3800 V6 Supercharged Engine
Your Park Avenue Ultra has a 3800 V6 Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The Supercharger is a device which is designed
to pump
more air into the engine than it would normally use.
This air mixed with fuel, creates increased engine
power. Since the Supercharger is a pump and
is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
250
ProCarManuals.com

The powertrain control module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost, is not desired such as during
idling and light throttle cruising, the excess air that the
Supercharger is pumping is routed through a bypass. All
of these controls, working together provide high
performance character and fuel efficiency in the
3800
V6 Supercharged Buick engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule’’ in the Index for when you
should check the fluid.
The supercharged
3800 engine uses two accessory drive
belts. One belt drives the generator and the power
steering pump. The second belt drives the supercharger,
coolant pump and air conditioning compressor. Each
belt has
its own tensioner and idler pulley. See
“Maintenance Schedule’’ in the Index for when you
should check the accessory drive belts and supercharger
oil level. Have your dealer check the oil level in the
supercharger.
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.
The engine oil dipstick is
directly behind the engine
fan. Turn
off the engine and
give the oil a few minutes
to get back down into the
oil pan. If you don’t, the oil
dipstick might not &ow the
actual level.

What Kind of Oil to Use:
Look for three things:
SG
“SG” must be on the oil container, either by itself or
combined with other quality designations, such as
“SG/CC,” “SG/CD,” “SF,SG,CC,” etc. These letters
show American Petroleum Institute (API) levels of
quality.
If you use oils that don’t have the “SG”
designation,
you can cause engine damage not I
covered by your warranty.

Engine Oil Additives: Don’t add anything to your oil.
Your Buick 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 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
Oil Soon” in
the Index.)
Engine Block Heater: An engine block heater can be a

The other label is the Certification label, found on the
rear edge of the driver’s door.
It tells you the gross
weight capacity
of your vehicle, called the GVWR
(Gross Vehicle Weight Rating). The GVWR includes
the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed
the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front
or rear
axle. And,
if you
do have a heavy load, you should spread it
out. Don’t carry more than
176 pounds (80 kilograms)
in your trunk.
.A CAUTION:
I
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWRs. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. These
could cause you to lose control. Also,
overloading can shorten the life of your vehicle.
If you put things inside your vehicle -- like suitcases,
tools, packages, or anything else
-- they will go as fast

Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on
the underbody. If these are not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or
an underbody vehicle washing system
can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etchgd into
the paint surface.
Although no defect
in the paint job causes this, Buick
will repair, at no charge to the owner, the surfaces
of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20
000 km) of purchase,
whichever comes first.
