1998 BUICK REGAL oil change

Have you recently cnanged brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand
you use. It will require at least one
full tank of the proper fuel
to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Qil Warning Light
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come on when
you are driving.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on
in the following
situations:
0
0 The light will come on briefly when you turn on the
ignition to show you that it is working properly.
(If it doesn’t come on with the ignition on,
you may
have a problem with the fuse or bulb. Have it fixed
right away.)
Sometimes when the engine is idling at a stop, the
light may blink on and off. This
is normal.

Change Oil Soon Light
Your CHANGE OIL SOON
light should come on as a
CHANGE OIL
SOON
bulb check when you start
the engine.
Security Light
SECURITY
This light will come on
when you turn the key
to
START and stay on until the
vehicle starts.
If this light stays on for about
20 seconds after you turn
on the ignition, have the oil changed.
When to change your oil also depends on driving habits
and conditions because
they directly affect engine speed,
coolant temperature and vehicle speed. Because of this,
the CHANGE OIL
SOON light may come on as early as
2,000 miles (3,200 km) or less for harsh conditions.
Also see “Maintenance Schedule” in the Index for
further instructions on when
to change your oil.
To reset the CHANGE OIL SOON light, see “CHANGE
OIL SOON Light, How to Reset” in the Index. Also, see
“Oil Life Monitor”
in the Index. It
will also flash if your ignition key is too dirty or wet
for the PASS-Key I1 system to read the resistor pellet.
See “Pass-Key
11” in the Index.
If the resistor pellet is damaged or missing, the light will
come
on.
If you’re ever driving and the SECURITY light comes
on, you will be able to restart your engine
if you turn it
off. Your PASS-Key I1 system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS-Key I1 system.

Modes
AVG ECON: Shows your average fuel economy since
you last reset this mode. Average fuel economy is
viewed as a long term approximation of your overall
driving and driving conditions. To learn the average fuel
economy from a new starting point, press the RESET
button while
the average fuel economy is displayed in
the
DIC.
INSTANTANEOUS FUEL ECONOMY Shows your
current fuel economy. Instantaneous fuel economy
varies with your driving conditions, such as
acceleration, braking and the grade of the road being
traveled. The instantaneous fuel economy display cannot
be reset, therefore the reset button has no effect while in
this mode.
OIL LIFE MONITOR: Shows an estimate of the oil’s
remaining useful life. When
the oil life index is less than
lo%, the CHANGE OIL SOON light will come on.
When you have the oil changed according to the
maintenance schedule (see “Maintenance Schedule” in
the Index), you will have to reset the oil life monitor.
To
do this, press and hold the RESET button for more than
five seconds while the oil life monitor is being displayed
on the DIC. The oil life will change
to 100%.
RANGE: Shows the approximate distance you can
drive without refueling. This
is based on the amount of
fuel in the tank and on the fuel economy of the most
recent
25 miles (40 km). Pressing RESET while in this
mode will have no effect.
BOOST GAGE: If you have the supercharged engine,
this gage will show
the amount of boost your engine is
receiving. Pressing RESET while in this mode will have
no effect.

What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
If you change your own oil,
be sure
you use oil that has
the Starburst symbol on the
front of the oil container.
I RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
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:

LOOK
FOR THIS
SYMBOL
COLD
WEATHER
DO NOT USE SAE 2OW-50 OR ANY OTHER FD

ProCarManuals.com

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.

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.
