Can ethanol fuel be used in any vehicle?
Response:
Gasoline-ethanol blends containing up to 10% volume
ethanol may be used in any vehicle. The addition of ethanol boosts octane
and, because it is an oxygenate, ethanol contributes to a more complete
fuel combustion resulting in reduced emissions of carbon monoxide and other
ozone-forming emissions. All major auto manufacturers approve the use of
up to 10% volume ethanol.
In fact, some manufacturers, such as General Motors,
Chrysler, Ford, Nissan, Range Rover, and Suzuki recommend the use of oxygenated
fuels and/or reformulated gasoline for their clean burning characteristics.
Blends above 10% volume are not approved by the auto manufacturers or the
EPA for use in standard gasoline engine vehicles.
The Energy Policy Act of 1992 also recognizes E85
(a blend of 85% ethanol and 15% unleaded gasoline) as an alternative fuel.
In order to operate on E85, vehicles need to be compatible with alcohol
use. The conversion cost to make FFVs compatible with E85 typically includes
upgrades to the fuel system components, the addition of a fuel sensor, and
reprogramming the EPOM (computer chip) in the ECM/PCM (electronic control
module/power train control module).
