Arvind Kejriwal, National Convenor of the Aam Aadmi Party (AAP), criticized the Indian government's rollout of E20 ethanol-blended fuel on Saturday.
The dispute highlights growing concerns over whether the transition to higher ethanol blends is harming vehicle performance and consumer wallets without sufficient government oversight.
Kejriwal visited a petrol pump and an automobile service station in Delhi to investigate the impact of the fuel. He said the government introduced E20 without conducting a prior study to determine its effects on vehicles [1]. He said the fuel is causing reduced fuel efficiency and potential engine damage [2].
Specific reports regarding the loss of efficiency vary. While some vehicle owners have reported reduced fuel efficiency [3], other reports indicate a sharper decline, with mileage dropping to five km per litre [4].
Kejriwal said the government is forcing the blend on consumers. He said the government should provide consumers with a choice at the pump and establish separate pricing for E20 and pure petrol [5].
Beyond vehicle performance, the AAP leader raised concerns about the economic implications of the policy. He said the push for higher blends could lead to a five-fold increase in ethanol imports [6].
Kejriwal said the lack of transparency regarding the rollout's impact on engines is unacceptable for the public.

The criticism from the AAP reflects a broader tension between India's environmental goals—reducing oil imports and carbon emissions through ethanol blending—and the practical readiness of the existing vehicle fleet. If E20 fuel causes significant engine degradation or efficiency loss in non-compliant vehicles, the government may face pressure to implement a phased rollout or provide subsidies for vehicle upgrades to avoid widespread consumer backlash.
