E20 Fuel News | Centre Admits E20 Petrol May Reduce Mileage By Up To 3-5%

The Centre has acknowledged that E20 petrol (20% ethanol-blended fuel) may reduce fuel efficiency by 3–5% in some vehicles, while stressing its long-term benefits, including cleaner combustion, lower emissions, and improved energy security. The clarification came through a detailed Q&A issued by the Ministry of Petroleum and Natural Gas amid concerns over the nationwide rollout. Auto experts say modern BS-VI (Euro 6 equivalent) vehicles are largely compatible with E20, but older vehicles may face engine damage or compatibility issues. Experts have also called for greater clarity and support for owners of non-compliant vehicles.
