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)
.
