fuel BUICK REGAL 1995 Owner's Manual

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the “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.
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.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use SAE 1OW-30 if it’s going
to be
0°F (- 18°C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as SAE
20W-50.

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

Inflation - Tire Pressure
The Tire-Loading Information label which is inside the
trunk lid shows the correct inflation pressures for your tires,
when they’re cold. “Cold” means your vehicle has been
sitting for at least three hours or driven no more than a mile.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not.
If your tires
don’t have enough
air (underinflation) you can
get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards. When to Check
Check
your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How
to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will
not tell you the
pressure, especially
if you have radial tires -- which
may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure
to put them back
on. They help prevent leaks by keeping out dirt and
moisture.

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.
Fiberglass Springs
~~ ~
NOTICE:
Don’t use corrosive or acidic cleaning agents,
engine degreasers, aluminum cleaning agents or
other harsh solvents
to clean fiberglass springs;
they’ll damage the springs.
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 etched 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.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
If you are skilled enough
to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. You will find a list of
publications and how to get them in this manual. See
“Service Publications”
in the Index.
“Part B: Owner Checks and Services” tells you what
should be checked whenever you stop for fuel. It also
explains what you can easily do to help keep your
vehicle in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your Buick dealer’s service
department or another qualified service center should
perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do
the work
yourself or have it done.
“Part E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance
is performed, be
sure to write
it down in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea
to keep your maintenance
receipts. They may be needed to qualify your vehicle for
warranty repairs.

Part A: Scheduled Maintenance
Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries.
Or you
may drive it to work, to do errands or in many other
ways.
Because of all the different ways people use their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than you’ll find
in the schedules in this section.
So please read this
section and note how you drive.
If you have any
questions on how to keep your vehicle in good
condition, see your Buick dealer.
This part tells you the maintenance services you should
have done and when you should schedule them.
If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts. The
proper fluids and lubricants to use
are listed in
Part
D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
These schedules are for vehxles that:
0
0
0
carry passengers and cargo within recommended
limits. You will find these limits
on your vehicle’s
Tire-Loading Information label. See “Loading Your
Vehicle” in the Index.
are driven on reasonable road surfaces within legal
driving limits.
use the recommended unleaded fuel. See “Fuel” in
the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule to follow:
7-3
ProCarManuals.com

Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a can-ier on top of
your vehicle.
Schedule
1 should also be followed if the vehicle is used
for delivery service, police, taxi, or other commercial
application.
