oil viscosity BUICK PARK AVENUE 1994 Owners Manual

What Kind of Oil to Use
Beginning midyear 1993, oils of the proper quality for
your vehicle
will be identified with this new “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.
You should look for this on the front of the oil container,
and
use only oils that display this new symbol.
You should also use the proper viscosity oil for your
vehicle, as shown
in the following chart:
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

ANY OTHER GRADE OIL NOT RECOMMENDED
DO NOT USE
SAE 1OW-40, SAE 2OW-50 OR

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 1OW-40 or SAE 2OW-50.
If you cannot find oils
with the new “starburst” symbol
on the front
of the container, you should look for and
use
oils containing the following three things:
0
0
0
SH or SG
“SH” or “SG” must be on the oil container, either by
itself or combined with other quality designations,
such as “SH/CD,” “SH,SG,CD,”
“SG/CD” etc.
These letters show American Petroleum Institute
(API) levels of quality.
SAE 1OW-30
Energy Conserving I1
Oils
with these words on the container will help you
save fuel. These
three things are usually included
in a doughnut
shaped logo (symbol) on most containers. If you cannot
find oils
with the “starburst” symbol, you should look
for oils
with the doughnut shaped symbol, containing
the three things noted above.
NOTICE:
If you use oils that do not have either the
“starburst” symbol or an
API SH or SG
designation, you can cause engine damage not
covered by your warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.

Explanation of Scheduled Maintenance
Services
Following are explanations of the services listed in
Schedule I and Schedule 11.
The proper fluids and lubricants to use are listed
in
Section 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.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification”
in the Index.
1. Engine Oil and Filter Change* -- Always use SH
or SG Energy Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be shown alone
or
in combination with others, such as “SH/CD” or
“SH,
SG, CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE
5W-30 or SAE low-30), see “Engine Oil” in
the Index.
If your vehicle has an Engine Oil Life Monitor, the
monitor will show you when to change the oil. See
“Engine Oil Life Monitor”
in the Index. 2.
Chassis Lubrication -- Lubricate
the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped
with grease fittings, lubricate the
suspension and steering linkage.
3. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following the instructions
in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
4. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
5. Cooling System Service* -- Drain, flush and refill
the system
with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant”
in the Index. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.

INSPECTION
OR SERVICE
Brake System
[nspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake
lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition.
Also inspect drum brake linings for
wear and cracks. Inspect other brake
parts, including drums, wheel
cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You
may need
to have your brakes inspected
more often if your driving habits or
conditions result
in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced, Also,
if the
brake system warning light stays on or
comes
on, something may be wrong
with the brake system. See ”Brake
System Warning Light”
in the Index. If
your anti-lock brake system warning
light stays on, comes on or flashes,
something may
be wrong with the
anti-lock brake system. See “Anti-Lock
Brake System Warning Light”
in the
Index.
