Kejriwal Alleges E20 Fuel May Harm Older Vehicles, Claims Auto Firms Face Pressure Over Safety Concerns

Yugcharan News | 29-07-2026

The national debate over India's transition to cleaner fuels has intensified after Aam Aadmi Party (AAP) National Convenor Arvind Kejriwal raised serious concerns regarding the government's implementation of E20 petrol. Addressing a press conference on Wednesday, Kejriwal alleged that several automobile manufacturers have privately expressed apprehensions about the use of E20 fuel in petrol-powered vehicles manufactured before 2023. He further claimed that these companies have refrained from making their concerns public due to alleged pressure from the Central Government.

The remarks have added a fresh political dimension to the ongoing discussion surrounding ethanol-blended fuel, a policy that the Centre has promoted as part of its strategy to reduce dependence on imported crude oil, lower carbon emissions, and support India's biofuel sector.

According to Kejriwal, he recently wrote to 29 automobile manufacturers operating in India, seeking clarity on whether vehicles produced before 2023 are fully compatible with E20 petrol. His letter also reportedly asked whether manufacturers would compensate vehicle owners in case the use of E20 fuel resulted in engine damage, reduced fuel efficiency, or other technical problems.

Speaking to the media, the former Delhi Chief Minister stated that none of the companies responded to his queries in writing. However, he claimed that representatives from nine automobile manufacturers held private conversations with him over the phone.

According to Kejriwal, officials from these companies allegedly conveyed that E20 petrol may not be suitable for many petrol-powered vehicles manufactured before 2023. He further claimed that the officials expressed concerns that prolonged use of E20 fuel in older vehicles could potentially affect engine performance and components of the fuel system.

The AAP leader also alleged that these company representatives informed him they were under pressure and unwilling to publicly disclose their technical concerns. According to his claims, the manufacturers feared possible consequences if they openly questioned the government's fuel policy.

These allegations have not been independently verified, and at the time of publication, no official statements had been issued by the automobile manufacturers named in Kejriwal's broader communication. Similarly, the Central Government had not publicly responded to these specific allegations.

During the press conference, Kejriwal questioned the government's decision to aggressively promote E20 petrol without, according to him, adequately addressing concerns related to existing vehicles on Indian roads. He estimated that nearly 30 crore vehicles manufactured before 2023—including around 22 crore two-wheelers and approximately eight crore four-wheelers—could potentially be affected if compatibility issues arise.

The AAP chief argued that millions of vehicle owners deserve clear answers regarding the long-term impact of E20 fuel on their vehicles. He said consumers should be informed about whether their vehicles are designed to safely operate on higher ethanol-blended fuel and whether manufacturers would assume responsibility if technical issues emerge.

Apart from safety concerns, Kejriwal also questioned the economic implications of the E20 programme. He claimed that ethanol-blended fuel could reduce mileage because ethanol has a lower calorific value than conventional petrol. According to him, if motorists receive fewer kilometres per litre, consumers could ultimately spend more on fuel despite government claims promoting the benefits of ethanol blending.

He further alleged that ethanol itself is more expensive than petrol in certain contexts and questioned whether the policy would deliver the expected financial advantages to consumers and farmers.

The E20 fuel programme has been one of the Centre's flagship initiatives under India's ethanol blending policy. E20 petrol contains 20 percent ethanol mixed with 80 percent petrol. The government has consistently maintained that increasing ethanol blending will reduce crude oil imports, strengthen India's energy security, lower greenhouse gas emissions, and create additional income opportunities for sugarcane growers and other agricultural producers involved in ethanol production.

Government agencies have also previously stated that automobile manufacturers have been preparing vehicles compatible with E20 fuel as part of a phased transition. Several manufacturers have announced that many of their newer models are designed to support E20 petrol, while compatibility for older vehicles may vary depending on the model and year of manufacture.

Industry experts have previously noted that ethanol-blended fuels can require modifications in engine components, rubber seals, fuel lines, and calibration systems in certain vehicles. However, compatibility largely depends on vehicle design, manufacturer specifications, and engineering standards. Many experts recommend that vehicle owners follow manufacturer guidelines regarding fuel compatibility rather than relying solely on general assumptions.

The controversy surrounding E20 has also highlighted the importance of transparent communication between policymakers, automobile manufacturers, and consumers. Vehicle owners across the country may seek greater clarity on whether their specific models are compatible with E20 petrol and whether any additional maintenance or precautions may be required.

The automobile industry has so far largely supported India's transition towards cleaner fuels while simultaneously working to upgrade vehicle technologies to meet evolving fuel standards. However, industry bodies have generally emphasised the need for phased implementation, consumer awareness, and adequate testing to ensure a smooth transition.

Political reactions to the issue are expected to continue as opposition parties question various aspects of the government's energy policies, while the Centre maintains that ethanol blending represents an important milestone in India's environmental and energy security goals.

As of now, Kejriwal's claims regarding conversations with officials from nine automobile companies remain unverified publicly. No documentary evidence or written responses from the manufacturers have been released to support these allegations. Likewise, the concerned automobile companies have not issued public statements confirming or denying the conversations referred to by the AAP leader.

The Centre has consistently defended its ethanol blending programme in previous public communications, describing it as an essential component of India's long-term clean energy roadmap. Government officials have also highlighted environmental benefits such as reduced carbon emissions and decreased dependence on imported fossil fuels.

With millions of petrol vehicle owners potentially seeking clarity over fuel compatibility, the debate is likely to generate increased public attention in the coming weeks. Industry experts believe that official guidance from automobile manufacturers and government agencies will play a crucial role in addressing consumer concerns and preventing confusion.

Until formal responses are issued by the companies concerned or the government provides further clarification, the discussion surrounding E20 fuel compatibility is expected to remain an important topic in India's automotive and energy policy landscape. Consumers are advised to consult their respective vehicle manufacturers' official recommendations before making any decisions regarding fuel usage, ensuring that their vehicles are operated according to approved technical specifications.
