1994 OLDSMOBILE BRAVADA fuel

If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation.
You
should probably stay with your vehicle
unless you know for sure that you are
near help and you can hike through the
snow. Here are some things to do to
su~nmon help and keep yourself and
your passengers safe: Turn on your
hazard flashers. Tie a red cloth to your
vehicle to alert police that you’ve been
stopped by the snow. Put on extra
clothing or wrap a blanket around you.
If
you have no blankets or extra clothing,
make body insulators from newspapers,
burlap bags, rags, floor mats
- anything
you can wrap around yourself or tuck
under
your clothing to keep warm.
You can run the engine to keep warm,
but be careful.
~ .--- . . .. . . .. ~ ~ ~, L
Run your engine only as long as you
must. This saves fuel. When
you run the
engine, make
it go a little faster than just
idle. That is, push the accelerator
slightly. This uses less fuel for the heat
that you get and it keeps the battery
charged.
You will need a well-charged
battery to restart the vehicle, and
possibly for signaling later on with your
headlights. Let the heater run for awhile.
Then, shut the engine
off and close the
window almost all the way to preserve
the heat. Start the engine again and
repeat this only when you feel really
uncomfortable from the cold.
But do it
as little as possible. Preserve the fuel as
long as you can. To help keep warm,
you can get out of the vehicle and do
some fairly vigorous exercises every half
hour or
so until help comes.

Your Driving and the Road
Towinga Trailer
NOTICE:
Pulling a trailer improperly can
damage your vehicle and result in
costly repairs not covered by your
warranty. To pull a trailer correctly,
follow the advice in this section,
and see your Oldsmobile dealer for
important information about
towing a trailer with your vehicle. Every Bravada is ready for some trailer
towing. If it was built with trailering
options, as many are, it’s ready for
heavier trailers. But trailering is different
than just driving your vehicle by itself.
Trailering means changes in handling,
durability, and fuel economy. Successful,
safe trailering takes correct equipment,
and it has to be used properly.
That’s thereason for this section. In it are
many time-tested, important trailering
tips and safety rules. Many
of these are
important for your safety and that of your
passengers.
So please read this section
carefully before you pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws having
to do with trailering. Make sure your
rig will be legal, not only where you
live but
also where you’ll be driving. A
good source for this information can
be state or provincial police.
Consider using a sway control if your
trailer will weigh
2,000 pounds (900
kg) or less. You should always use a
sway control if your trailer will weigh
more than
2,000 pounds (900 kg). You
can ask
a hitch dealer about sway
controls.
Don’t tow a trailer at all during the
first
500 miles (800 lun) your new
vehicle is driven. Your engine, axle or
other parts could be damaged.
Then, during the first 500 miles (800
km) that you tow a trailer, don’t drive
over
50 mph (80 km/h) and don’t
make starts at full throttle. This helps
your engine and other parts of your
vehicle wear in at the heavier loads.
Three important considerations have
to
do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
5,250
pounds (2 380 kg). But even that can be
too heavy.
It depends on how you plan to use your
rig. For example, speed, altitude, road
grades, outside temperature and how
much your vehicle is used to pull a
trailer are all important. And, it can also
depend on any special equipment that
you have on your vehicle.

Engine Fan Noise
This vehicle has a clutched engine
cooling fan. When the clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most everyday
driving conditions the clutch is not
engaged. This improves fuel economy
and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or
high outside temperatures, the fan speed
increases when the clutch engages.
So
you may hear an increase in fan noise.
This is normal and should not be
mistaken as the transmission slipping or
making extra shifts. It is merely the
cooling system functioning properly.
The fan will slow down when additional
cooling is not required and the clutch
disengages. You may also hear this fan
noise when you start the engine. It will
go away
as the fan clutch disengages.
I Ifa Tire Goes Flat
It’s unusual for a tire to “blow out”
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire
will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require
the same correction you’d use in a skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes
flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.
I Changing a Flat Tire
If a tire goes flat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn
on your hazard
warning flashers.

Fuel
Use regular unleaded gasoline rated at
87 octane or higher. Use premium
unleaded gasoline rated at 91 octane or
higher for high power performance,
when towing a trailer or with a high
payload requirement. But when
operating with a light load as
a normal
condition, you may use middle grade or
regular unleaded gasolines.
The gasoline you use should meet
specifications ASTM D4814 in the U.S.
and CGSB
3.5-92 in Canada. These
fuels should have the proper additives,
so you should not have to add anything
to the fuel.
In the
U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see “UNLEADED” right
on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least 91
for premium, 89 for middle grade and
87 for regular.
If the octane is less than
87, you may get a heavy knocking noise
when you drive. If it’s bad enough, it
can damage your engine.
If you’re using fuel rated at 91 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t worry
if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal, and
you don’t have to buy a higher octane
fuel to get rid of it. It’s the heavy,
constant knock that means you have a
problem.
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or
alcohol?
MTBE is “methyl tertiary-butyl ether.”
Fuel that
is no more than 15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more than
10% ethanol is
fine for your
vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5%
methanol is bad for your vehicle.
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. And even at
5% or less, there must be
“cosolvents” and corrosion
preventers in this fuel to help avoid
these problems.
GasoUnes for Cleaner Air
Your use of gasoline with deposit
control additives will help prevent
deposits from forming in your engine
and fuel system. That helps keep your
engine in tune and your emission
control system working properly. It’s
good for your vehicle, and you’ll be
doing your part for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors

recommends that you use gasolines
with these blending materials, such as
MTBE and ethanol. By doing
so, you
can help clean the air, especially in
those parts of the country that have
high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed
to reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline. By doing
so, you
can help clean the air, especially in
those parts of the country that have
high ozone levels.
You should ask your service station
operators if their gasolines contain
deposit control additives and
oxygenates, and if they have been
reformulated to reduce vehicle
emissions.
Fuels in Forei’ Countries
If you plan on driving in another
country outside the
U.S. or Canada,
unleaded fuel may be hard to find.
Do
not use leaded gasoline. If you use even
one tankful, your emission controls
won’t work well or at all. With
continuous use, spark plugs can get
fouled, the exhaust system can corrode,
and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means
costly repairs that 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
Fuel Capacity: 20 U.S. Gallons (76 L)
Use unleaded fuel only.
The cap is behind a hinged door on the
left side
of your vehicle.
To take
off the cap, turn it slowly to the
left (counterclockwise). Be
careful not to spill gasoline. Clean
gasoline from painted surfaces as soon
as possible. See
Cleaning the Outside
of Your Oldsmobile in the Index.
When you put the cap back on, turn it to
the right until you hear a clicking noise.
NOTICE:
If you need a new cap, be sure to get
the right type.
Your dealer can get
one for you. If you get the wrong
type, it may not fit
or have proper
venting, and your fuel tank and
emissions system might be damaged.

Engine Oil
It’s a good idea to check your engine oil
every time you get fuel. In order to get
an accurate reading, the oil 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.
To Check 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 lower.
When to Add Oil
If the oil is at or below the ADD line,
then you’ll need to add some oil. But
you must use the right kind. This
section explains what kind of oil to use.
For crankcase capacity, see
Capacities
G. Specifications in the Index.
NOTICE:
Don’t add too much oil. If your
engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper operating
range, your engine could be damaged.
~~
Just fill it enough to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when you’re through.
