fuel Oldsmobile Aurora 1998 s Owner's Guide

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate
on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If this occurs, return
to your authorized Aurora retailer for diagnosis to
determine the cause of failure. In the event
it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may
be affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Aurora retailer for service. To
provide cleaner air, all gasolines in the United States
are now required
to contain additives that will help
prevent deposits from forming in your engine and
fuel system, allowing your emission control system
to
function properly. Therefore, you should not have to
add anything to the fuel. In addition, gasolines
.
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Fuels in Foreign Countries
If you plan on driving in another country outside the
United States
or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel
not
recommended in the previous text on fuel. Costly repairs
caused by
use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell
us where you’re going and give your
Vehicle Identification Number
(VIN).

Filling Your Tank
,A CAUTION: I
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.

The cap is behind a hinged door on the left side of
your vehicle.
The remote fuel door release can help keep your fuel
tank from being siphoned. Always be sure the fuel door
is closed and latched after refueling.
To open the fuel door (on
the driver's side of the
vehicle), press the button
next to the trunk release
button, to the right of the
steering column. The
ignition does not need to
be
on. The remote fuel door
release will work in all
transaxle positions. The fuel
door can
be opened
manually in case
of an
electrical power failure. To
do so, first open the trunk.
The release mechanism is
on the driver's side
of the
vehicle, at the top
of the
trunk compartment. Pull
the tab toward you to
release the
fuel door.
NOTICE:
Prying on a locked fuel filler door could damage
it. Use the remote fuel door manual release
located
in the trunk.

To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if
you let go of the cap too soon, it will spring back
to the right.
While refueling, hang the tethered cap from the hook
on the fuel door.
If you get gasoline on yourself and then
something ignites
it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank
is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait
for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.
When you put the cap back
on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install
the cap. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to
evaporate into the atmosphere. See “Malfunction
Indicator Lamp”
in the Index.
6-7

NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you.
If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
FYng a Portable Fuel Container
I-
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if
this
occurs. To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
CAUTION: (Continued)
I
!
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

OIL
If the CHECK OIL LEVEL
message
or the oil warning
light
on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see “Check Oil Level Message”
or “Oil Pressure Warning Light” in the Index. You
should check your engine oil level regularly; this
is
an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the 02 must
be warm and the vehicle must be on level ground.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push
it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.

As shown in the chart, SAE low-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

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

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by
a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread is badly worn, or
if your tires have
been damaged, replace them.
I
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
rear edge of the driver’s
door, 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 1 mile (1.6 km).
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 the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.

Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your retailer or other service
outlets. Larger areas
of finish damage can be corrected
in your retailer’s body and paint shop.
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 retailer or an underbody car washing system can
do this for you.
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,
Oldsmobile 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 occurs first.
