Kerala launches fuel quality checks following E20 ethanol controversy

Kerala's fuel regulatory authorities have begun unannounced checks at petrol stations in four districts to verify fuel composition, responding to growing concerns about ethanol content in motor gasoline. The move follows claims by Karnataka officials that petrol supplies contain ethanol concentrations as high as 31.2 percent, significantly exceeding permissible limits.

The inspections were prompted by complaints from vehicle owners who reported performance issues and mechanical problems potentially linked to substandard fuel quality. Authorities are testing fuel samples to determine whether supplies meet established quality standards and investigate the source of any contaminated batches.

E20 fuel, which contains up to 20 percent ethanol, remains a contentious issue in India's automotive sector. While the government has promoted ethanol blending to reduce emissions and dependence on crude oil imports, concerns persist about the fuel's compatibility with older vehicles and potential engine damage from excessive ethanol concentrations.

The Kerala inspection follows similar quality-control actions across other states grappling with fuel adulteration concerns. Authorities have not yet released preliminary findings from the ongoing checks, and officials said they would coordinate with fuel distributors and suppliers to address any violations discovered.
