engine oil BUICK REGAL 1998 Owner's Manual

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 (1 6 O 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 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F
(-29”C), consider using either an SAE 5W-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Monitor. This feature
will let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t detect dust
in the oil. So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the CHANGE OIL
SOON light when the oil has been
changed. For more information, see “Change Oil Soon
Light” in the Index.
How to Reset the CHANGE OIL SOON Light
After changing the engine oil, the system must be reset.
With the ignition key in RUN but the engine off, fully
push and release the accelerator pedal slowly three times
within five seconds. If
the CHANGE OIL SOON light
flashes, the system is resetting.
Turn the key to OFF,

then start the vehicle. If the CHANGE OIL SOON light
comes back on, the system has not reset. Repeat the
procedure.
(If you have a driver information center, the
system may be reset by depressing the DIC
RESET
button for five seconds while viewing the oil life display
on the DIC. See “Driver Information Center” in
the Index.)
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t
let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment.
If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams
or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
To check or replace the air
filter, loosen the wing nut
on the air duct and lift
up on
the two clips located on the
top of the filter cover.
Disconnect the duct and
reposition
it while removing
the side cover.
Pull out the filter. Be sure
to install the air filter and
install the cover tightly when you are finished.
Refer
to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services’’ in the Index.

How to Check and Add Oil
Check oil only when the engine is cold. Allow the
engine
to cool two to three hours after running.
~ ~ -
A CAUTION:
If you remove the supercharger oil fill plug while
the engine is hot, pressure may cause hot oil to
blow out
of the oil fill hole. You may be burned.
Do
not remove the plug until the engine cools.
1.
2.
3.
4.
Clean the area around the oil fill plug before
removing it.
Remove the oil fill plug using a
3/ 16 inch
Allen wrench.
The oil level is correct when it just reaches the
bottom of the threads of the inspection hole.
Replace the oil plug with the O-ring
in place. Torque
to
88 lb-in (10 N-m).
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32” C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the
fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough
of the proper
fluid to bring the
level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at
the
dipstick hole to bring it to the proper level.
It doesn’t take much fluid, generally less than one
pint
(0.5 L). Don’t overfill.
NOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than
DEXRON-I11
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How to Check.” 4.
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL6 extended life coolant.
J
The following explains your cooling system and how to
add coolant when it is low. If
you have a problem with
engine overheating or if you need
to add coolant to your
radiator, see “Engine Overheating”
in the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.
6-23
ProCarManuals.com

NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or radiator corrosion may result.
In addition, the
engine coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
you don’t need to add anything
E :.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid
-- such as Delco Supreme 1 l@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean
the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
1
NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care’’ in
the Index.

I Maintenance Schedule I
The services shown in this schedule up to 100,000 miles
(166
000 km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles
(240 000 km) should be performed at
the same interval after
150,000 miles (240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
The U.S. Environmental Protection Agency or the
California Air Resources Board 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 the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 000 km)
and 7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
without an oil and filter change.
The system won’t detect dust in the oil.
So if you drive
in a dusty area, be sure to change your oil and filter
every
3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light comes
on. Remember to reset the Oil
Life Monitor when the oil has been changed. For more
information,
see “Change Oil Soon Light” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
