Flex Fuel capability allows certain 2018 Toyota Tundra trucks to run on either E85 or regular unleaded gasoline. These Flex Fuel models are identified by the "FFV" designation in their names. Examples include the 5.7L Limited FFV Crewmax RWD and 4WD SB, the 5.7L SR5 FFV double cab RWD and 4WD SB, and the 5.7L Platinum FFV Crewmax RWD and 4WD SB, among others.
