India Considers Delaying E25 Fuel After E20 Backlash

The Government of India is considering a delay in the rollout of E25 petrol, which contains a 25 percent ethanol blend, following significant backlash over the rapid transition to E20 fuel. The government had advanced its target for E20 fuel by five years, making it the current national standard. However, high-level discussions last week concluded that any further transition toward E25 must be gradual and based on a scientific approach to allow manufacturers and the ecosystem to adapt.

The policy has faced criticism from both motorists and fuel retailers. In New Delhi, drivers protested the E20 mandate, citing reduced fuel efficiency, higher maintenance costs, and engine damage. Similarly, the Odisha Petroleum Dealers Association has urged a return to a 10 percent blend (E10), reporting that E20 has caused mechanical failures, such as jammed carburettors, even in some BS-6 models. Additionally, petrol dealers claim that oil marketing companies have failed to honor a 2024 commitment to review retail margins every six months.

Automakers have offered mixed responses. While some executives from Maruti Suzuki, Hyundai Motor India, and Toyota Kirloskar Motor defend the E20 rollout and attribute reported engine damage to contaminated fuel, they acknowledge that E25 would require significant engine recalibration and corrosion-resistance testing. Despite these challenges, the government maintains that higher ethanol blending is a strategic necessity to reduce carbon emissions and crude oil imports.
