Arvind Kejriwal, Chief Minister of Delhi and leader of the Aam Aadmi Party, has challenged automobile manufacturers to prove E20 petrol is safe.
The dispute centers on whether the government-mandated fuel blend damages vehicle components or reduces efficiency, potentially leaving millions of consumers with degraded assets. While the central government maintains the program is scientifically sound, Kejriwal said he possesses evidence that contradicts this position.
Kejriwal sent letters to 29 automobile manufacturers, including Hero MotoCorp, Toyota Kirloshar, and Maruti Suzuki, seeking clarity on the safety of the fuel. The Indian government has mandated a 20% ethanol blend, known as E20 [1]. This nationwide rollout was completed in April 2026 [2].
Government officials said that the ethanol-blending program is backed by science and that the fuel is safe for vehicles. However, Kejriwal said he wants manufacturers to provide concrete proof to protect consumer safety. He questioned the Centre's claims that the program would not affect vehicle performance.
Consumer reports suggest a gap between government assurances and user experience. A survey found that approximately 50% of petrol-vehicle owners experienced lower mileage following the E20 rollout [3].
In related policy moves, the Centre has exempted certain higher-blend fuels from excise duty. These exemptions apply to fuels with 22%, 25%, 27%, and 30% ethanol, referred to as E22 through E30 [4].
The push for higher ethanol blending is part of a broader strategy to reduce oil imports and lower carbon emissions. However, the friction between political leadership and the automotive industry highlights concerns over the technical readiness of existing vehicle fleets for these chemical changes.

This conflict reflects a tension between India's aggressive green energy targets and the practical durability of its automotive infrastructure. If E20 fuel is proven to cause component degradation or significant mileage loss, the government may face liability claims or a public backlash against its biofuel transition strategy.
