India introduced 20 percent ethanol-blended petrol, commonly known as E20, ahead of schedule in 2025. The initiative has helped the country save billions in fuel import costs while offering advantages such as higher octane levels and lower emissions. However, studies have indicated that vehicles may experience a reduction in fuel efficiency ranging from 1 percent to 6 percent. Critics have claimed that older vehicles could suffer mileage losses of up to 20 percent.
The controversy intensified after a Bharat Petroleum Corporation Limited executive stated that ethanol contains lower energy content than conventional petrol. The remark triggered widespread criticism and public debate over the fuel's performance. Following the backlash, the company clarified that the lower energy content of ethanol does not adversely affect vehicle performance.
Union Minister Nitin Gadkari dismissed allegations that ethanol-blended fuel damages vehicle engines, describing such claims as propaganda promoted by the petroleum lobby. He reiterated support for the ethanol blending programme amid continuing debate over its impact on vehicle efficiency and long-term performance.
At the same time, concerns have emerged over the Delhi-Dehradun Expressway, which was inaugurated by Prime Minister Narendra Modi on April 14. Built at a cost of approximately Rs 12,000 crore, the 210-kilometre expressway was designed to reduce travel time between Delhi and Dehradun to nearly two and a half hours.
Following recent rainfall, cracks and potholes reportedly appeared on sections of the newly opened expressway, raising serious questions about construction quality and commuter safety. The visible damage has sparked criticism and renewed demands for accountability over the execution of the high-value infrastructure project.
The National Highways Authority of India is supervising repair work under the project's defect liability provisions. Even as restoration work continues, concerns remain over quality control, durability, and oversight of major public infrastructure investments.
The simultaneous criticism surrounding India's ethanol fuel programme and the Delhi-Dehradun Expressway has intensified public debate over the balance between rapid development, technological transition, and infrastructure quality. While the government continues to defend both initiatives, demands for transparency, accountability, and long-term reliability are expected to remain at the centre of public and political discussion.
