* Engine Compatibility: E85 fuel requires specific engine modifications to run properly. These modifications include:
* Fuel System: E85 is highly corrosive and requires special fuel lines, pumps, injectors, and fuel tank materials.
* Engine Components: E85 has a lower energy density than gasoline, requiring adjustments to the engine's fuel-air mixture and ignition timing.
* Sensors: E85's different chemical properties can affect fuel sensors and other engine control components.
* Year of Manufacture: E85 fuel was not widely available until the late 1990s and early 2000s. Vehicles from the 1991 model year were not designed to use this type of fuel.
