India ongoing debate over E20 petrol has taken a fresh turn after Chief Economic Adviser V. Anantha Nageswaran called for the return of lower-ethanol petrol such as E10 alongside E20. E20 petrol contains 20% ethanol and has been the standard petrol supplied across India since April 1, 2026. The policy is aimed at reducing crude oil imports, improving energy security and lowering emissions.
However, the nationwide rollout has faced concerns from vehicle owners, particularly those using older cars and two-wheelers. Some consumers have reported concerns about mileage, vehicle performance and compatibility with older components.
In an opinion article co-authored with Department of Economic Affairs consultant Akash Poojari, Nageswaran suggested that making E10 available alongside E20 could address much of the public concern. He noted that India has around 75-80 million older two wheelers, some of which may have older rubber seals that were not designed for higher ethanol blends. The suggestion does not mean the has pib officially decided to bring E10 back. The government had previously said there was no proposal to revert to lower-blended petrol.
The Petroleum Ministry broader position remains that E20 is a tested fuel supporting India energy-security and environmental goals. The government has also stated that E20 has undergone extensive testing and that claims of widespread engine damage are not supported by available evidence. For now, the E20 debate continues, with consumer choice and protection of older vehicles emerging as key issues.
