what happened
Karnataka minister Rizwan Arshad said on Monday that the state is sticking with its report claiming oil marketing companies blend more than 20% ethanol into petrol. The state earlier said it tested samples from seven districts, most of which showed ethanol shares above 20%, reaching as high as 31.2%.
State-run IOCL, BPCL and HPCL rejected these findings. They said E20 petrol supplied nationwide meets IS 17021, the Bureau of Indian Standards specification, and that the October testing took place without their representatives. The Ministry of Petroleum and Natural Gas also said all 893 E20 samples met quality standards.
Arshad argued that the sampling process was transparent and that the labs are NABL-accredited, claims the companies dispute. He warned that such blending could damage vehicle engines and burden ordinary consumers.
why it matters
For markets, the dispute matters mainly as a regulatory risk for state-run refiners and ethanol suppliers, since disagreements over testing methods could prolong the issue and affect supplier reputations. The story has no direct impact on global oil prices.
