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.
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).
