Amid a backlash over the introduction of 20% ethanol-blended petrol (E20), the Centre has not only emphasised that the move will help reduce pollution and save money on oil imports, but also said that the formulation leads to better acceleration and even ride quality. 

On claims that mileage has taken a significant hit because of E20 petrol, the Ministry of Petroleum and Natural Gas said the concerns had been anticipated as far back as 2020. Mileage, it also said, is influenced by several factors, including driving habits, maintenance, tyre pressure and "air conditioning load".
