Gasolines for Cleaner Air

Your use of gasoline with deposit control 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 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

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

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.
