India’s ethanol rush prompts anger among vehicle owners, questions for gov’t | Automotive Industry News
Fuel Transition Sparks Concerns Among Indian Motorists
When Krishna Kumar visited a petrol station in New Delhi several months ago, he anticipated a routine fuel stop. Instead, he discovered that E20 petrol—a blend consisting of 20 percent ethanol—was the only option available. With limited choices, he filled his tank.
Shortly thereafter, the bank employee observed changes in his petrol sedan’s performance. Once reliably efficient and responsive, his vehicle began to exhibit sluggish acceleration, especially when driving uphill or using the air conditioning. Kumar noted that his mileage slipped from approximately 18-20 kilometers per liter to about 16-17 kilometers per liter, translating to a decline of over 10 percent. “All that has changed is the fuel,” he stated.
Kumar’s experience mirrors that of countless car owners across India as the country embarks on one of the world’s swiftest transitions to higher ethanol-blended petrol. Under the National Policy on Biofuels, the government, led by Prime Minister Narendra Modi, has accelerated its target for achieving a 20 percent ethanol blend from 2030 to 2025, making E20 mandatory at petrol stations last year. Initial concerns over this rapid shift had been raised by consumers, but calls for a policy review gradually dissipated.
In June 2026, the Indian government’s attorney general caused a stir by informing the Supreme Court that the administration was “experimenting” with the 20 percent ethanol blend. The government later contended that this statement was misunderstood, but the comments triggered widespread backlash from car owners, analysts, and opposition politicians questioning the policy’s implications.
Proponents of the E20 initiative argue that it will reduce reliance on imported crude oil, enhance energy security, cut greenhouse gas emissions, and boost agricultural income by increasing demand for crops like sugarcane and maize. However, critics point to decreased vehicle mileage—a concern acknowledged by federal Minister of Road Transport and Highways Nitin Gadkari—as well as claims that the fuel blend may be damaging internal car components. Opposition parties have alleged a conflict of interest involving Gadkari due to family ties to companies engaged in ethanol production.
At the center of this debate is a pressing question: why has the government pursued such a rapid rollout of E20 petrol?
Kumar expressed the need for greater public awareness about how E20 could affect older petrol vehicles, emphasizing the importance of informing car owners to help them make informed decisions about their vehicles’ performance.
Ethanol Blend Challenges
Supporters tout the initiative as a pivotal step toward cleaner energy, while critics underscore the immediate repercussions of reduced fuel efficiency and compatibility concerns for millions of older vehicles on the road. Although automobile manufacturers began equipping new vehicles with E20-compliant materials in 2023, fully compliant models will not be available until 2025. The government asserts that older vehicles can safely use E20 with regular maintenance, yet many owners are uncertain about the potential long-term effects on engines not originally designed for higher ethanol blends.
Anas Khan, a businessman in New Delhi, reported noticeable declines in both mileage and engine performance since switching to E20. He said his 2021 Maruti Suzuki Baleno’s efficiency fell from about 18 kilometers per liter to nearly 15 kilometers per liter, with sluggish acceleration becoming particularly evident during city driving.
Sajad Ahmad Wani, an independent automobile expert, explained that the impact of E20 is largely contingent on the vehicle’s design and age. While vehicles not designed for higher ethanol blends might not show immediate issues, prolonged use may result in accelerated wear of rubber and fuel components not suited for ethanol. He noted that drivers may experience a decrease in mileage due to ethanol’s lower energy content.
Mechanics like Bilal Ahmad are also noticing more customers reporting decreased engine performance post-E20 switch, suggesting a connection between the new fuel and these issues, even if effects vary by vehicle.
The Indian government contends that most concerns from motorists are unfounded. The Ministry of Petroleum and Natural Gas maintains that studies conducted by various research organizations indicate no significant differences in engine performance or longevity for older vehicles using E20. They claim that any marginal decrease in fuel efficiency—estimated to be around 1 to 2 percent—can often be mitigated by regular servicing.
Union Transport Minister Nitin Gadkari has vigorously defended the ethanol policy, asserting that it fosters economic growth for farmers while lessening India’s dependence on foreign oil.
However, energy experts highlight that while the implementation of E20 has been robust from a supply perspective, the trade-offs for consumers are emerging. They note that while the nation’s overall oil demand may decrease, it won’t drop proportionately to the levels of ethanol used in fuel.
Environmental and Economic Considerations
Environmental experts caution the E20 initiative sparks broader sustainability concerns. Although ethanol can lower overall greenhouse gas emissions relative to traditional petrol, the cultivation of water-intensive crops like sugarcane may exacerbate pressures on already limited water resources in some regions. Furthermore, the shift toward more lucrative fuel production over food cultivation raises questions about future food security.
Maharashtra, a significant sugar-producing state, has rapidly expanded its ethanol production due to government incentives and a robust network of sugar mills, bolstering its position at the forefront of India’s biofuel strategy. The sector’s growth has rekindled scrutiny over the political dynamics surrounding ethanol production.
Gadkari’s staunch advocacy for ethanol has drawn criticism due to perceived conflicts of interest linked to his family’s involvement in agro-processing and ethanol production. He has refuted allegations of impropriety, asserting that all decisions regarding ethanol pricing and procurement are collectively made by the cabinet.
Consumer advocacy groups have called for more transparency around ethanol blending levels at petrol stations, insisting that motorists deserve clear information about the fuels they purchase, especially given the significant presence of older, non-E20 compatible vehicles in circulation.
In contrast to Brazil, where flex-fuel vehicles widely use ethanol, India’s transition to E20 occurs amidst the operation of millions of older vehicles, heightening concerns around compatibility and consumer awareness.
For motorists like Kumar and Khan, the issue is not merely about energy policy but the tangible effects on their driving experiences. “Even though my car is only a few years old and is regularly serviced, it doesn’t feel as smooth or responsive as before,” Khan remarked.
