Oil Marketing Companies dispute state government claims of 31% ethanol in petrol

Oil Marketing Companies (OMCs) have disputed the state government's claim that petrol sold in some Karnataka petrol pumps contains 31% ethanol. The OMCs stated that the alleged confusion may be due to testing not being conducted according to prescribed rules and technical standards. IOCL, BPCL, and HPCL jointly stated that the petrol they supply, which is E 20, complies with IS 17021 standards set by the Bureau of Indian Standards (BIS).
