How is a FFV different from a gasoline-only vehicle?
A FFV will contain a fuel sensor that detects the ethanol/gasoline ratio. In addition, a number of other parts on the FFVs fuel delivery system are modified so that they are ethanol compatible. The fuel tank, fuel lines, fuel injectors, computer system and anti-siphon device have been modified slightly. This normally includes a stainless steel fuel tank and Teflon-lined fuel hoses. The use of E85 in gasoline-only vehicles is not recommended as it may cause damage due to the incompatibility of the alcohol fuel (ethanol) with the parts in gasoline-only engines. Performance and emissions may also be compromised.
