The Society of Indian Automobile Manufacturers (SIAM) has withdrawn its earlier communication to the Ministry of Petroleum and Natural Gas regarding E20 fuel contamination, stating that media reports had selectively quoted excerpts from the document and that some of the figures cited require further verification.

  1. Earlier communication withdrawn pending further verification
  2. SIAM reiterates support for the government's E20 programme
  3. Petroleum Ministry says enhanced fuel quality checks are in place

The clarification follows media reports that cited portions of the communication relating to chloride and moisture contamination in E20 petrol and an increase in the replacement of certain vehicle components.

SIAM says figures require further verification

In a statement issued on Tuesday night, SIAM said, "SIAM has taken note of certain media reports that have cited excerpts from a SIAM communication, with specific and selective focus on chloride and sulphur content in fuel. SIAM wishes to clarify the matter and place it in its correct context for the benefit of the public and all stakeholders."

It added that the communication was part of routine technical discussions between industry bodies, automobile manufacturers, oil marketing companies (OMCs) and testing agencies.

"Some numbers quoted in the communication needs authentication through collection of elaborate data from various regions across the country followed by a comprehensive consultation with our member OEMs," SIAM said.

The industry body added, "The referred numbers reported in the media need authentication and therefore SIAM is withdrawing its earlier communication."

A news report published by a leading business channel on Tuesday, which has since been removed, had cited excerpts from the communication, claiming SIAM had flagged a rise in the replacement of fuel injectors, fuel pumps and other components, while also highlighting chloride contamination of up to 500mg/kg in some fuel samples.

Industry body reaffirms support for E20 rollout

SIAM said the Ministry of Petroleum and Natural Gas has already introduced a 3ppm guideline for chloride and sulphur in ethanol blended into petrol, while OMCs have strengthened quality checks across the fuel supply chain. According to the industry body, "all of these steps fully meet the needs of the automobile industry." 

The industry body also reiterated its support for the nationwide rollout of E20 petrol, stating that there is "no cause for concern" for consumers and that such technical issues have routinely been addressed between automakers and OMCs.

Government reiterates fuel quality monitoring

Earlier on Tuesday, the Petroleum Ministry said fuel quality is monitored regularly by state-run OMCs and highlighted enhanced testing protocols following reports related to SIAM's communication on E20 fuel quality.
