India seeks to quell fears over ethanol blended petrol

By the Editorial Team · Sunday, July 12, 2026

India is addressing motorist concerns about the use of E20 ethanol-blended petrol amid fears of engine damage and increased maintenance costs. Despite ongoing public debate, officials cite gradual implementation, input from automakers, and data showing no widespread harm, while highlighting logistical challenges in offering multiple fuel options.

India is working to address concerns from motorists regarding the expanded use of ethanol-blended petrol, specifically E20 fuel, which contains 20 percent ethanol. The push to increase ethanol blending, led by Prime Minister Narendra Modi’s government, aims to reduce oil imports and lower vehicle emissions. However, social media posts have raised fears that E20 could damage engines or increase maintenance costs in vehicles not designed for higher ethanol content.

The Ministry of Petroleum and Natural Gas acknowledged that E20 fuel may result in a 3 to 5 percent decrease in fuel economy but denied that there is scientific evidence supporting claims of engine damage. Officials emphasized that the transition to E20 has been made gradually, with consultation from automobile manufacturers. Data from Maruti Suzuki, India’s largest carmaker, was cited showing that none of the 28.4 million vehicles serviced by the company during the 2025-2026 financial year exhibited corrosion, abnormal wear, or damage linked to E20 fuel.

Toyota India also addressed complaints raised in a viral social media post involving one of its vehicles, attributing the issue to fuel contamination rather than the use of E20 petrol. Additionally, Bharat Petroleum, a state-owned oil refining company, rejected claims that E20 petrol attracts ants, stating its investigations found no substances in the fuel that would draw insects to fuel caps.

Despite official reassurances, public debate continues online, on television programs, and at a recent protest in New Delhi. Critics of the ethanol program have called on the government to provide consumers with options including unblended petrol, E10 (10 percent ethanol blend), and E20 fuel. The Petroleum Ministry countered that offering multiple fuel grades nationwide would pose significant logistical challenges. These would include increased handling costs, complex inventory management, and reduced operational efficiency across India’s extensive fuel distribution network.

As the government pushes forward with its ethanol blending initiative, it continues to balance environmental and energy security goals against public concerns and practical difficulties in fuel supply management.
