Kerala Launches Petrol Quality Checks Across Four Districts Following Karnataka Ethanol Blend Row

The Kerala government has initiated surprise inspections at petrol pumps across four districts, collecting random fuel samples for laboratory testing to measure ethanol blending ratios and fuel density. The statewide checks were ordered after neighbouring Karnataka reported that retail petrol samples contained ethanol concentrations reaching up to 31.2%—far exceeding the federally mandated E20 cap of 20%. Official laboratory findings for the Kerala government E20 test results are currently underway, with detailed reports expected within 10 days.

State civil supplies inspectors in Kerala began the random inspections following consumer complaints regarding vehicle engine damage and erratic performance. Officials are conducting preliminary fuel density tests on-site at retail outlets before sealing and dispatching samples to state laboratories for chemical analysis. A conclusive Kerala government E20 test result will establish whether public sector oil marketing companies in the state are maintaining mandated quality standards or whether local fuel supplies exhibit the excessive ethanol levels recently alleged in Karnataka.

The inter-state fuel controversy flared up after Karnataka conducted an audit of retail petrol outlets and challenged major public sector oil companies over their fuel mix. Karnataka officials claimed that several fuel samples collected across the state surpassed the E20 threshold, with readings registering as high as 31.2% ethanol. The dispute escalated online when Bharat Petroleum Corporation Limited (BPCL) published a post on X as part of its ‘MythVsFact’ awareness campaign, showcasing an ethanol blend test at a petrol pump in Mysuru, Karnataka. Alert social media users noticed that the testing apparatus in BPCL’s photo showed an ethanol concentration of 33%. BPCL deleted the post shortly after, sparking further political debate between state leaders and oil majors.

Centre disputes claims, cites nationwide fuel audit

The Union Ministry of Petroleum and Natural Gas rejected Karnataka’s test findings, asserting that all public sector oil marketing companies strictly observe mandatory blending regulations. To counter the allegations, the Centre cited its own nationwide testing drive, where 893 samples of E20 petrol collected from public sector outlets across 27 states and Union Territories were analyzed. The ministry stated that every single sample met the prescribed fuel quality and density standards. Public sector oil marketing companies also issued formal denials, rejecting claims that petrol containing up to 31% ethanol was sold at any retail outlet.

Union Minister Suresh Gopi defended the Centre’s E20 blending policy, stating that both Kerala and Karnataka have full authority to sample and test petrol at retail outlets within their borders. Warning against turning fuel quality testing into political point-scoring, Gopi stated that the Centre’s E20 program remains on solid footing and that any increase in the national ethanol mix beyond 20% will occur gradually over time.

Inspectors across Kerala are continuing sample collection at pumps in the four designated districts. The upcoming Kerala government E20 test result will reveal whether fuel sold by oil marketing companies in Kerala abides by the 20% ethanol limit or mirrors the 31.2% readings reported across the border.
