E20 row: Karnataka stands by 31% ethanol claim, questions oil firms' explaination

The Karnataka government stands by its findings that petrol samples contained more than 20 per cent ethanol, state minister Rizwan Arshad said on Monday, rejecting oil companies’ explanation that the issue was limited to a few outlets.Arshad argued that blending was an automated, controlled process and questioned how excess ethanol could be confined to individual outlets.His remarks are the latest in a row that began with the state government’s fuel-testing findings on Friday.Congress MP Rahul Gandhi cited laboratory results the following day to accuse oil companies of exceeding the prescribed blending limit. Arshad has since questioned whether higher blending was being introduced unofficially.

The samples were initially sent to the companies’ laboratories, along with questions seeking details of their ethanol content. On Saturday, Rahul Gandhi cited samples collected from seven districts to question both public sector and private oil companies.The Leader of Opposition in Lok Sabha claimed that 11 of 14 samples tested at an accredited laboratory contained more than 20 per cent ethanol.“E20 turned into 420,” Gandhi wrote on X, accusing the companies of “stealing petrol from the public’s cars” and questioning the transparency of their testing processes.KUMARASWAMY’S REMARKS ON HIGHER BLENDING“Over the last 3-4 months, I have seen the Central Government planning to raise Ethanol blending from 20% to 30%” Confirms Union Minister Shri HD Kumaraswamy, at a press conference in Bengaluru.
