What Is Flex Fuel? Understanding the Fuel Powering the Future of Sustainable Transportation
Flex fuel refers to an alternative automotive fuel system that allows vehicles to operate using petrol blended with varying amounts of ethanol, a renewable biofuel produced from agricultural crops such as sugarcane, corn, and biomass. Vehicles designed with flex fuel technology can automatically adjust to different fuel mixtures, including high-ethanol blends, without requiring major engine modifications or affecting overall driving performance.
