E100? Govt wants to go beyond E20 amid concerns over impact of ethanol on older vehicles

India's aggressive ethanol blending program, aimed at reducing crude oil imports, is raising concerns for vehicle owners. Vehicles designed for E10 fuel may experience a 1-2% drop in mileage with E20 blends, impacting millions manufactured between 2012 and March 2023. Automakers are urging tax incentives to offset this, while the government signals further intensification of the ethanol push.
