Gasolines far Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits fron
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.
