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.
I
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.
