Supreme Court To Hear PIL Against Mandatory E20 Fuel Policy On This Date

Updated: Friday, August 29, 2025, 13:54 [IST]

A Public Interest Litigation (PIL) has reached the Supreme Court against the Centre's decision to make E20 fuel compulsory across India. The plea, filed by advocate Akshay Malhotra, raises concerns about the lack of choice for India's motorists and the compatibility of older vehicles, as well as safety issues.

The PIL filed before the Supreme Court argues that millions of vehicles sold in India before April 2023 were not designed to run on 20 per cent ethanol-blended petrol, better known as E20. The petition filed with the Supreme Court also states that even some newer BS-VI models may not be fully compliant with E20, which could potentially expose owners to mechanical issues, reduced efficiency, and higher repair costs.

Ethanol-blended petrol can corrode metal parts and damage plastic and rubber components inside older engines. Fuel efficiency could take a hit when running on E20 (something the government has acknowledged), increasing operating costs for daily users who rely on two-wheelers and cars alike.

Making matters worse, some insurers may deny claims if engine failures or fires are linked to ethanol-related damage, as it is not the recommended fuel for older vehicles. Owners, therefore, face the risk of financial losses without any legal safeguard while being forced to use fuel that their vehicles were not built to handle.

Another major concern raised is pricing. Even though petrol containing 20 per cent ethanol E20 is apparently cheaper to produce than refined petrol, the Indian government has not lowered the retail prices of the blended fuel. Malhotra's PIL argues that Indian motorists have been denied the cost benefits that result from the blending programme.

To address the concerns raised in his PIL, Malhotra has requested the Supreme Court of India to direct fuel retailers to provide ethanol-free petrol (E0) alongside E20. Malhotra is also for the mandatory labelling of ethanol content at all pumps to help widen public awareness regarding the compatibility of different vehicles with blended fuel.

The PIL additionally calls for a comprehensive nationwide study on the long-term effects of E20 fuel. This includes analysing its impact on engine performance, emissions, component wear, and consumer costs. Malhotra's plea stresses that any nationwide rollout of E20 blended fuel must be supported by a transparent scientific evaluation.

The PIL will be heard on September 1, 2025, before a bench led by the Chief Justice of India B.R. Gavai, along with Justices K. Vinod Chandran and N.V. Anjaria. Their decision could have significant implications for both vehicle owners and the government's ethanol policy.

India adopted E20 fuel earlier this year, five years ahead of schedule. The government has set a larger target of achieving 30 per cent ethanol blending (E30) by 2030. While the government's ethanol blending policy aims to cut crude imports and lower emissions, the PIL suggests that vehicles sold in India may not be ready for the transition to these higher ethanol-petrol blends.

The upcoming hearing for the PIL about E20 blended fuel will test how India balances its renewable energy goals with consumer protection. Whatever decision is made, it will decide whether E20 remains compulsory or whether motorists will regain the option of choosing ethanol-free petrol.

What Is E20 Fuel?

E20 is an alcohol-blended fuel, commonly produced by mixing Ethanol (ethyl alcohol) made from crops like sugarcane or maize with Petrol in a 20:80 blend.
