Rahul Gandhi cites Karnataka petrol tests to question E20 blending; oil companies reject the findings
As of the evening of 7 November: the Karnataka government's samples reportedly showed up to 31.2% ethanol against a 20% limit; the three state-run oil companies say the testing did not follow prescribed procedures.
Lok Sabha Leader of Opposition Rahul Gandhi on Saturday, 7 November, accused the government and oil companies of supplying petrol with more than the prescribed 20% ethanol under the E20 programme, citing laboratory tests of samples collected by the Karnataka government, per Outlook and Asianet Newsable. This piece is as of the evening of 7 November.
What was alleged
In a post on X, Gandhi wrote that Karnataka collected petrol samples from seven districts and had them tested at an accredited laboratory; 11 of 14 samples contained more than 20% ethanol, with 31.2% at IOCL and 30.5% at HPCL, according to Orissa Post and National Herald. He said samples associated with IOCL, HPCL, BPCL, Nayara and Shell all exceeded the limit, and that the companies' own laboratories did not report ethanol content (Asianet Newsable). His post said "E20 turned into 420" and referred to the penal code section on cheating (National Herald). Gandhi argued that higher ethanol content could cut mileage and raise maintenance costs, and questioned the lack of labels at fuel stations disclosing ethanol content, per Orissa Post.
The oil companies' response
The state-run Indian Oil Corporation, Bharat Petroleum and Hindustan Petroleum rejected the findings, arguing that the testing was not conducted in accordance with prescribed statutory and technical procedures, and that E20 petrol supplied nationwide conforms to Bureau of Indian Standards specifications (Outlook). Outlook adds that they cite 893 samples found within limits. National Herald says the companies also cite Rs 1.97 lakh crore in foreign exchange savings from the ethanol-blending programme since 2014-15.
What is unresolved
Outlook says the dispute puts the Petroleum Ministry and oil companies under pressure to establish whether the reported excess blending reflects a breach of fuel quality standards or discrepancies in sampling and testing. The Karnataka government's own figures are known through Gandhi's account and these outlets' summaries; none of the reports we read independently tested the fuel.
Still open
- Whether the gap reflects excess blending or differences in sampling and testing, as Outlook frames the dispute; the Petroleum Ministry's response is not reported in these outlets.
- How the Karnataka samples were drawn and tested; the reports we read give no independent verification.
