Service and Appearance Care
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 prevent-
ers 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 gasalines are now blended with
oxygenates. General Motors recommend:
that you use gasolines with these blendin,
materials, such as MTBE and ethanol. BJ
doing
so, you can help clean the air,
especially
in those parts of the country
that have high carbon monoxide levels. n
addition, some gasoline suppliers are
low producing reformulated gasolines.
rhese gasolines are specially designed to
.educe vehicle emissions. General Motors
-ecommends that you use reformulated
;asoline. By doing
so, you can help clean
:he air, especially in those parts of the
:ountry that have high ozone levels.
You should ask your service station
3perators if their gasolines contain deposit
:ontrol additives and oxygenates, and
if
:hey have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
[f 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
:lub, or contact a major oil company that
Joes business in the country where you’ll
,e driving.
You can also write us at the following
iddress for advice. Just tell
us where
you’re going and give your Vehicle
Identification Number (VIN).
