oil viscosity BUICK PARK AVENUE 1993 Owners Manual

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.
0 Energy Conserving I1

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.”

Explanation of Scheduled Maintenance
Services
Below 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 SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or
“SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE
5W-30 or SAE 10W-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.
* An Emission Control Service.

6.
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.
Throttle Body Mounting Bolt Torque” -- Check
the torque
of the mounting bolts and/or nuts.
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.
Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
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.
The U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.

INSPECTION
OR SERVICE
Brake System
Inspection
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 or
comes on, something may be wrong
with
the anti-lock brake system. See
“Anti-Lock Brake System Warning
Light”
in the Index.
Section D: Recommended Fluids and
Lubricants
NOTE: Fluids and lubricants identified below by name,
part number or specification may be obtained from your
GM dealer.
