India's leading carmakers, including Maruti Suzuki, Tata Motors, and Mahindra, have privately expressed serious concerns about contamination in E20 petrol, which contains 20% ethanol, according to a Reuters report cited by livemint.com. These concerns emerged despite the companies' public support for the fuel blend, highlighting a disconnect between their public stance and internal apprehensions.
The concerns surfaced through internal emails reviewed by Reuters, revealing that these automakers flagged potential issues related to fuel contamination that could affect vehicle performance and durability. The revelations come shortly after India's automobile lobby withdrew a formal complaint about the E20 petrol rollout, indicating ongoing tensions within the industry regarding the fuel's implementation and quality control.
E20 petrol is part of India's broader strategy to increase ethanol blending in fuels to reduce carbon emissions and dependence on imported oil. However, contamination concerns from major car manufacturers could impact the adoption and acceptance of this fuel blend. Maruti Suzuki, Tata Motors, and Mahindra are among the largest players in India's automotive market, making their reservations significant for policymakers and fuel suppliers.
The internal communications reviewed by Reuters and reported by livemint.com were published on August 13, 2026, providing a rare glimpse into the private challenges faced by India's auto industry amid the government's push for cleaner fuels.
