Kanpur: Amid concerns over the nationwide rollout of 20 per cent ethanol-blended petrol (E20), researchers at IIT Kanpur on Tuesday claimed that their studies found no significant drop in fuel efficiency and "no evidence" that E20 harms engines in either existing or older vehicles.
The reported findings follow Oil Ministry's clarification last week stating that E20 can reduce mileage by up to 5 per cent in some vehicles, but the impact is outweighed by several benefits, including a lower lifecycle carbon emissions.
