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.
To find out if your car can run on cheaper flex fuel, check your ownerâs manual or look for an E85 label on the fuel door , a yellow gas cap or a badge on your car with the term âE85,â âFlex Fuel,â or âFFV.â.
