The government amended vehicle rules to recognise E100 fuel for certified flex-fuel vehicles. This move supports efforts to cut crude-oil imports by allowing blends up to 100% ethanol.

The govt has amended vehicle rules to formally recognise E100 fuel, allowing certified flex-fuel vehicles designed for blends up to 100% ethanol to use it.
