India’s ethanol-blended petrol policy faces renewed scrutiny as the government continues to push for higher ethanol content in fuel, despite growing concerns among consumers and industry experts about its impact on older vehicles. Chief Economic Adviser V Anantha Nageswaran has called for restoring the availability of E10 fuel, petrol blended with 10% ethanol, at petrol pumps specifically for older vehicles, arguing that this could address public concerns and allow time for necessary retrofits to accommodate E20 fuel. This recommendation comes amid ongoing debates over whether the current mandate requiring all petrol to be blended with 20% ethanol is feasible for India’s diverse vehicle fleet. The Ethanol Blended Petrol Programme, introduced to cut reliance on fossil fuels and support sugarcane farmers, mandates that all petrol sold in the country must contain 20% ethanol. However, critics argue that this policy overlooks the technical limitations of older vehicles, particularly those with carburetor-based engines. These engines, common in India’s large population of two-wheelers, struggle to adjust to the higher oxygen content in E20 fuel, leading to potential issues with engine overheating and reduced fuel efficiency. Additionally, older rubber seals in these vehicles are not designed to handle ethanol exposure, risking deterioration and leaks unless replaced with ethanol-compatible parts, a costly and time-consuming process. Nageswaran and co-author Akash Poojari, a consultant in the Department of Economic Affairs, highlighted that India has approximately 75 to 80 million older two-wheelers that rely on carburetors. Retrofitting each of these vehicles with compatible components would require extensive resources and time, potentially taking years to complete. By reintroducing E10 fuel, they argued, the government could provide a temporary solution that protects the existing fleet while retrofitting efforts progress. This approach, they claimed, would also help reduce overall ethanol consumption rather than increasing it further. The government, however, has resisted calls to reintroduce E10, citing logistical challenges associated with maintaining multiple fuel grades across India’s vast fuel distribution network. In a recent statement, the Ministry of Petroleum noted that managing different fuel blends would complicate inventory control, raise handling costs, and reduce operational efficiency. It emphasized that unlike premium fuels, which are niche products sold in limited quantities, E10 and E20 would require widespread infrastructure changes, making the task impractical. Despite these objections, concerns persist about the suitability of E20 for older vehicles. A recent opinion poll by LocalCircles revealed that 53% of petrol vehicle owners viewed the government’s handling of the E20 rollout as either “disastrous” or “ineffective.” Opponents argue that the government failed to adequately assess the readiness of the existing vehicle fleet before implementing the policy. Meanwhile, state-owned oil companies have dismissed allegations of fuel contamination, stating that nationwide tests of E20 petrol found no evidence of excessive moisture or chloride levels. They claim that the fuel quality remains within prescribed limits throughout the supply chain. Supporters of the E20 mandate, including Union ministers Hardeep Singh Puri and Nitin Gadkari, have defended the policy, emphasizing that it followed rigorous testing and stakeholder consultations. Puri accused critics of creating unnecessary controversy, pointing out that only four out of 107,000 petrol pumps showed irregularities during inspections. Gadkari reiterated that tests on engine durability, emissions, and material compatibility confirmed E20’s safety for use under standard conditions. He also noted that exhaust emissions from vehicles using E20 met the required BS-VI norms. As the debate continues, the government faces mounting pressure to balance environmental goals with practical considerations for millions of vehicle owners. With the retrofitting of older vehicles likely to take years, the call for a phased approach, allowing E10 alongside E20, gains traction. Whether the government will heed this advice remains uncertain, but the issue underscores the complexity of transitioning to cleaner fuels in a rapidly evolving automotive landscape.
