what happened
Indian Oil, BPCL and HPCL have rejected claims by the Karnataka government that petrol at some retail outlets contained 26% to 31% ethanol, above the 20% limit. According to Moody's, citing ANI, the companies said the October 2026 sampling was carried out without their representatives and that they had not received retention samples or laboratory reports.
The OMCs said their E20 fuel meets BIS standard IS 17021 and that a joint check of 893 samples across 27 states and union territories showed ethanol within the 19-21% range. Karnataka's own estimate puts the combined motorist burden at about Rs 1.01 lakh crore a year, a figure the companies dispute as unscientific.
why it matters
The dispute centres on fuel quality and testing methods rather than overall supply. For markets it matters mainly as a regulatory issue for India's ethanol blending program and retail fuel sellers, not as a driver of global oil prices.
