Clean Air Gasoline
Many gasolines are now being blended to con-
tribute to cleaner air, especially in those areas
where air pollution levels are high. These new
blends provide a cleaner burning fuel and some
are referred to as “reformulated gasoline.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
CNG And LP Fuel System
Modifications
Modifications that allow the engine to run on
compressed natural gas (CNG) or liquid pro-
pane (LP) may result in damage to the engine,
emissions, and fuel system components. Prob-
lems that result from running CNG or LP are not
the responsibility of the manufacturer and may
void or not be covered under the New Vehicle
Limited Warranty.
Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these mate-
rials intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and dia-
phragm materials.
