E20 row: Keralam to test petrol for excess ethanol blending after Karnataka findings

The Keralam government has ordered tests on petrol samples from four districts following allegations that oil companies are selling fuel with ethanol content above the prescribed limit. Food and Civil Supplies Minister Anoop Jacob has directed officials to collect samples from outlets in Thiruvananthapuram, Ernakulam, Kozhikode and Kannur.Jacob said the decision followed discussions with Chief Minister VD Satheesan. The samples will be tested at laboratories accredited by the National Accreditation Board for Testing and Calibration Laboratories (NABL) in the respective districts. Officials have also said forensic laboratories are equipped to conduct the tests.Jacob warned that strict action would be taken if the tests establish that petrol contains more than the permitted 20% ethanol. He said there had been no complaints of excessive blending in Keralam so far, but allegations from Karnataka prompted the state to conduct preventive checks.The inspections follow a dispute between the Karnataka government and oil marketing companies over the ethanol content of petrol sold in the state. Karnataka Food and Civil Supplies Minister Rizwan Arshad said tests on 63 samples collected from seven districts found that several exceeded the E20 limit, with the highest reading at 31.2%.The Karnataka government said nearly four out of five samples tested had ethanol content above 20%.
