India will begin rolling out up to 100 E85 fuel dispensing stations across key urban corridors, including the National Capital Region (NCR), Mumbai, Pune and Nagpur, as part of a phased expansion plan to promote flex-fuel adoption in the country, Petroleum Minister Hardeep Singh Puri said on Thursday.
