NEW DELHI: The government is reportedly exploring the possibility of bringing back E10 petrol through existing high-octane fuel variants, amid growing consumer concerns over the impact of E20 petrol on vehicle mileage and older engines.

According to reports, the Petroleum Ministry is discussing the proposal with state-run oil marketing companies, including Indian Oil, Bharat Petroleum and Hindustan Petroleum. The plan could involve offering E10 petrol through premium brands such as XP95, Speed and Power95, potentially avoiding the need for separate storage and dispensing infrastructure.

E10 petrol contains 10% ethanol, compared with 20% in E20 fuel. While the government has promoted E20 as part of its ethanol-blending programme, concerns have grown among vehicle owners over reduced fuel efficiency and compatibility with older vehicles.

Demand for higher-octane petrol has reportedly increased significantly as motorists with older or non-E20-compatible vehicles look for alternatives. Sales of 95-octane fuel have risen from around 4% in March to nearly 15%, according to industry reports.

However, the proposal remains under consideration and no final decision has been announced. The government has previously maintained its commitment to E20, while discussions over providing consumers with additional fuel options continue.

The possible return of E10 could offer motorists another choice while addressing concerns surrounding fuel efficiency and compatibility, particularly for vehicles designed for lower ethanol blends.
