Hardeep Puri rejects social media claims on E20 engine damage
The Times of India··8 Jul
Oil Minister Hardeep Singh Puri on July 7, 2026, rejected social media claims that India's E20 ethanol-blended petrol programme causes engine damage in compatible vehicles, calling them a misinterpretation. He said automobile manufacturers and vehicle service providers report no difficulties with E20. India rolled out E20 nationwide from April 2025 and had used E15 for over three years before that.
