E20 doesn't damage vehicle, only cuts fuel efficiency in older cars: Gadkari to Parliament

Union Road Transport Minister Nitin Gadkari told the Lok Sabha that E20 fuel doesn't damage a car or affect its engine durability, startability, corrosion resistance and material compatibility under prescribed standards. "Legacy vehicles don't exhibit variation in performance or abnormal wear and tear due to E20," Gadkari said. He noted that E20 reduces old E10-compliant vehicles' mileage by 2-6%.
