The nationwide rollout of E20 petrol has become a political issue. As people complain of engine damage and lower mileage, the Opposition has accused the government of forcing E20 petrol on people.

Citizens and consumers generally have two demands: one, do not force E20 on everyone but give people the option to buy pure petrol; and two, reduce the price of E20 petrol to reflect its lower calorific value and lower mileage.

Are these fair demands? How have other countries managed the rollout of ethanol-blended petrol? How can India make this transition better?

We speak with Vinay Piparsania, an engineer from IIT, Delhi and an independent automotive consultant who was with Ford Motor Company for over 20 years.
