Gasolines for Cleaner Air
Your use of gasoline with detergent 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 materials called
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 detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
F’uels 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.

Just tell us where you’re going and give your Vehicle Identification Number
