1993 OLDSMOBILE SILHOUETTE fuel additives

Fuel
Use regular unleaded gasoline rated at
87 octane or higher. It 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 87.
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 87 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 pinging. It’s the heavy,
constant knock that means you have a
problem.
What about gasoline with blending
materials that contain oxygen, 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.
Fuel Capacity: 20 U.S. Gallons (76L).
Use unleaded fuel only.

Gasolines for Cleaner Air
Your use of gasoline with detergent
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
materials called 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
detergents and oxygenates, and
if they
have been reformulated to reduce
vehicle emissions.

Fuels in Foreign 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.
