Unleaded E20 fuel controversy: Is non-blended gasoline still accessible for Indian consumers? Insights into the matter at hand
The Indian government has taken a significant step towards promoting cleaner fuel and reducing dependency on fossil fuels by implementing E20 petrol (20% ethanol blended petrol) nationwide. This move is part of the Ethanol Blended Petrol (EBP) Programme, which aims to support environmental goals and improve energy security [1][5].
Accelerating the Ethanol Blending Target
The EBP Programme, which began in 2003, has seen a steady increase in ethanol blending. From 10% in 2021-22, the target has been accelerated to 20% by 2025, a milestone that India achieved ahead of schedule [1][5].
Benefits for Car Performance
E20 petrol offers several advantages for car performance. With a higher octane rating (~108.5) compared to traditional petrol (84.4), E20 enhances fuel quality and supports modern high-compression engines, improving ride quality and engine performance [2].
Scientific studies and testing by Indian institutions, including ARAI and IIP, found no significant adverse effects on engine performance, material compatibility, or wear-and-tear for both new and older vehicles running on E20 [2][4]. In fact, vehicles designed and tuned for E20 show even better performance metrics [2].
While there is a slight drop in fuel efficiency (about 1-2% for vehicles designed for E10 and calibrated for E20, and 3-6% for others), engine tuning and the use of E20-compatible materials help mitigate this efficiency loss [4]. New vehicle models compliant with E20 have been introduced since April 2023.
Environmental and Economic Benefits
The shift to E20 petrol has resulted in a significant reduction in carbon dioxide emissions—approximately 700 lakh tonnes—helping India meet its climate change commitments [4]. The increased use of ethanol also improves India’s energy security by reducing crude oil import dependence [2].
A Technically Sound and Responsible Approach
The implementation of E20 followed a phased, multi-stakeholder approach with extensive coordination among government ministries, vehicle manufacturers, fuel companies, and regulatory agencies, ensuring readiness and minimizing disruption [2][3].
Addressing Misconceptions
The Oil Ministry has dismissed concerns about fuel efficiency related to E20 and listed out several benefits, including improved acceleration. They have also addressed baseless fearmongering about E20 affecting car performance and insurance coverage [3].
A Step Towards Sustainable Energy
The implementation of E20 petrol is part of a national program to reduce reliance on fossil fuels, decrease greenhouse gas emissions, and promote sustainable energy alternatives [3]. The shift to E20 is a testament to India's commitment to a cleaner and more sustainable future.

- The increase in ethanol blending under the Ethanol Blended Petrol (EBP) Programme, which targets 20% ethanol blending by 2025, echoes the Indian government's finance-driven focus on promoting cleaner fuel and advancing environmental science.
- The scientific community, including ARAI and IIP, has confirmed that E20 petrol, with its higher octane rating, offers improved engine performance and compatibility, thereby supporting modern vehicles and the wider industrial sector.
- Transitioning to E20 petrol has environmental benefits, significantly reducing carbon dioxide emissions and aiding India's commitment to climate change reduction, while concurrently enhancing energy security via reduced crude oil import dependency.
- The finance and environmental science industries can collaborate to propel the Indian industry further, promoting sustainable energy practices like E20 petrol to foster a cleaner and more eco-friendly future, as demonstrated by this nationwide implementation.
