E20 petrol may cut mileage 2–6% in older vehicles, ministries say
Government estimates indicate vehicles built for E10 petrol could see a 2–6% mileage decline on E20, while another minister cited 3–5%. The government rejected claims of a more substantial efficiency loss, a key consumer consideration as E20 availability expands.
Indian ministries said older vehicles designed for E10 petrol may see a 2-6% mileage decline when using E20, versus a separately cited 3-5% estimate. The government rejected claims of substantial fuel-efficiency losses.
Why this matters
The mileage estimate adds a consumer-impact issue to Indian Oil’s fuel-supply picture, following signals on E20 rubber-part replacements for pre-2016 vehicles and its purchase of ADNOC Upper Zakum crude.
