fuel additives OLDSMOBILE AURORA 1995 Owners Manual

Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Aurora” in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Index.
I NOTICE: 1
If you try to do your own service work without
knowing enough about it, your vehicle could be
damaged.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher. It should meet specifications ASTM D48 14 in
the United States 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 United States 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. If the octane is
less than
91, you may get a heavy knocking noise when
you drive. (In an emergency, you may be able to use
lower octane
-- as low as 87 -- if heavy knocking does
not occur.) If you’re using 91 or higher octane unleaded
gas and
you still get heavy knocking, your engine needs
service.

What about gasoline with blending materials that
contain oxygen (oxygenates), such
as MTBE or alcohol‘?
MTRE is “methyl tertiary-butyl ether.” Fuel that is no
more than
15% MTBE is fine for your vehicle.
Ethcrnol is ethyl or grain alcohol. Properly-blended fuel
that
is no more than 10% erhd is fine for your
vehicle.
Metlmzol 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.
Gasolines 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
L. zasolines contain deposit control additives and
oxygenates, and
if they have been reformulated to
reduce vehicle emissions.
