The withdrawal of SIAM's letter and the government's clarification are likely to reassure markets and consumers, reducing fears of widespread fuel quality issues that could affect vehicle performance and fuel demand. The event may have a mildly positive impact on automakers and oil marketing companies by alleviating regulatory uncertainty and supporting the continued rollout of E20 fuel.
The Automotive industry in India (SIAM) withdrew its July 28 communication to the India — Ministry of Petroleum and Natural Gas that had flagged potential chloride and moisture contamination in E20 petrol, which could damage fuel pumps and injectors. SIAM stated that media reports selectively quoted the letter and that the figures cited require further verification through broader data collection and consultation with member OEMs. The India — Ministry of Petroleum and Natural Gas responded by clarifying that fuel quality is regularly monitored by oil marketing companies, noting that over 2,000 samples have been tested for chloride and sulphide, with only two instances of chloride contamination found nationwide, and that sales from those outlets were suspended. The ministry also highlighted enhanced testing protocols, including water ingress testing 8-12 times a day at over 87,000 outlets. SIAM reaffirmed its support for the government's E20 initiative, emphasizing its importance for energy security and stating there is no cause for concern.
