SIAM withdraws earlier letter to Govt that had flagged chloride-related concerns with E20
The Society of Indian Automobile Manufacturers (SIAM) has withdrawn a letter that previously alleged E20 fuel caused corrosion and wear in vehicle parts. SIAM stated the data required further authentication, effectively retracting its challenge to the government's stance on blended fuel safety.
Why it matters
The retraction impacts the ongoing debate over the viability and safety of ethanol-blended fuels in India's automotive sector and the credibility of industry-government communications.
The Society of Indian Automobile Manufacturers (SIAM) late on Tuesday (August 4, 2026) withdrew its earlier letter to the government that had flagged concerns about vehicular parts experiencing either corrosion or wear due to the high chloride presence in E20 fuel, saying the data would require further authentication.
In its latest statement, the auto industry body said that the concerns it had earlier raised had since been addressed.
A draft of the earlier letter to the Ministry of Petroleum and Natural Gas (MoPNG) accessed by The Hindu stated, “SIAM members are observing huge increase in the issues in customer vehicle parts and replacement (like fuel injectors, fuel pump, exhaust gas recirculation valve, exhaust and other parts that are in direct contact with fuel or engine emission gases).”
