Union Minister for Road Transport Nitin Gadkari addressed concerns regarding E20 fuel potentially reducing vehicle mileage, noting that this measurement cannot be verified by individuals at home. His comments followed a journalist's report that her car's fuel efficiency had fallen from 10 kmpl to 7 kmpl. Gadkari stated that since the necessary testing equipment is not available in homes, owners should take their vehicles to authorized company dealerships for accurate mileage checks.
