Fuel
Use regular unleaded gasoline rated at 87 octane or
higher.
It should meet specifications ASTM D4814 i.n
the United States and CGSB 3592 in Canada. These
hels should have the proper additives,
so you should not
have to add anything to the fuel.
h the United States and Canada, it’s easy to be sure you
get the right kind
of gasoline (unlea.ded). 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.
Lf you’re using fuel rated at 87 octane or higher and you
still hear heavy hocking, 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 dan’t have to buy a higher octane fuel to get rid
of pinmg. 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.
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

Gasolines for Cleaner Air Fuels in Foreign Countries
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.
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.

vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0°F (- 1 8 O C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as SAE 20W-50.
