India’s push for E20 petrol is raising concerns about its impact on vehicle mileage. Experts indicate that the lower calorific value of ethanol compared to petrol is a key factor. This means that ethanol produces less energy when burned, potentially reducing fuel efficiency by 2-5%. While newer vehicles are becoming E20 compatible, older models may face challenges.
