1993 BUICK PARK AVENUE fuel

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.

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.

This doughnut-shaped logo (symbol) is used on most oil
containers to help you select the correct oil.
You should look for this on
the oil container, and use
only those oils that display the logo.
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 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:
0 Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less
The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
than
10 miles
(16 km).
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
big help
if you have to park outside in very cold
weather,
-20” F (-29 “C) or colder. If your vehicle has
this option, see “Engine Block Heater.”

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.
