Union Minister for Road Transport and Highways, Nitin Gadkari, has issued a direct challenge to those criticizing the E20 petrol rollout, asking them to name a single vehicle that has developed issues due to the blended fuel. His comments, made on Tuesday, July 8, 2026, come amidst growing concerns from motorists reporting reduced fuel efficiency and increased scrutiny over the compatibility of E20 with existing vehicles.
Defending Ethanol Blending Initiatives
Gadkari firmly defended India's ethanol blending program, asserting that there have been no documented cases of cars encountering problems specifically because of E20 petrol. He dismissed the criticism as potentially being part of "false narratives" and "paid campaigns" aimed at undermining the initiative.
India has successfully achieved a 20 percent ethanol blend with petrol, utilizing biomass sources such as sugarcane, corn, and rice. This strategic move is primarily aimed at significantly reducing the nation's heavy reliance on imported crude oil, which currently costs India an estimated ₹22 lakh crore annually. Furthermore, the program is designed to mitigate carbon emissions, addressing both economic burden and environmental hazards.
Addressing Allegations and Economic Impact
Responding to allegations that his family members' companies, involved in sugar production, benefit from the push for higher ethanol-blended petrol, Gadkari clarified that while his family owns sugar factories, their companies are not dependent on ethanol production. He highlighted the positive economic impact of ethanol production, particularly from corn, stating that it generated an additional ₹45,000 crore for farmers in Uttar Pradesh and Bihar. This occurred as corn prices rose from ₹1,200 per quintal (below MSP) to ₹2,800 per quintal after the decision to produce ethanol from it.
Insights from ARAI Study on E20 Compatibility
Amid the debate, a study conducted by the Automotive Research Association of India (ARAI) provided insights into the long-term effects of E20 fuel. The study indicated that prolonged use of E20 in vehicles originally designed for E10 could gradually impact rubber components within the fuel system, such as hoses, gaskets, seals, and O-rings, potentially requiring their replacement over time. However, no adverse impact was observed on metallic parts, and emissions from E10-compatible vehicles running on E20 remained within prescribed legal limits.
The ARAI study also noted varied engine durability results across different four-wheeler manufacturers. While one manufacturer reported no issues after 400 hours of testing, another observed a thermomechanical failure of an exhaust valve after 809 cumulative test hours, though non-E20 factors could have contributed. For two-wheelers, tests across three manufacturers found no issues, but fuel consumption with E20 was approximately 2 percent to 6 percent higher compared to E10, depending on the model.
Future of Fuel Blends
The Ministry of Road Transport and Highways has proposed amendments to the Central Motor Vehicles Rules, 1989, to broaden the scope for higher ethanol blends and alternative fuels. These draft changes aim to facilitate the wider adoption of fuels like E85, E100, B100 bio-diesel, and hydrogen-CNG combinations, paving the way for flex-fuel and pure bio-fuel vehicles across various categories in India.
