Carmakers on E20: No engine damage, but mileage drops | India News - The Times of India
NEW DELHI: Coming to the defence of govt amid backlash over the impact of mandatory 20% blending of ethanol in petrol, vehicle manufacturers on Saturday said there was no evidence of damage to engines, although they admitted to 3-3.5% drop in fuel efficiency in pre-2023 vehicles. The fall in mileage was on account of E20 petrol having lower calorific value.
