Pseudoscience describes any belief system or methodology which tries to gain legitimacy by wearing the trappings of science, but fails to abide by the rigorous methodology and standards of evidence that are the marks of true science.
1 Flex-fuel hybrid electric and flex-fuel plug-in hybrid are two types of hybrid vehicles built with a combustion engine capable of running on gasoline, E-85, or E-100 to help drive the wheels in conjunction with the electric engine or to recharge the battery pack that powers the electric engine.
Automobiles that can run on E85 are usually referred to as Flex Fuel or Alternative Fuel Vehicles, (FFV and AFV). The vehicle's gas cap will always state when up to 85% ethanol (E85) is permitted. E85 fuel should never be used in a conventional gas-powered vehicle.utomobiles that can run on E85 are usually referred to as Flex Fuel or Alternative Fuel Vehicles, (FFV and AFV).
