Guwahati, July 4 -- Bhutan has declined an offer from Indian Oil Marketing Companies (OMCs) to supply E20 petrol, opting instead to continue importing conventional petrol from India, citing concerns over ageing fuel storage infrastructure and the suitability of ethanol-blended fuel for the country's terrain.

According to a report by The Bhutanese, Bhutan has requested India to continue supplying normal petrol for as long as it remains available in the Indian market.

The Bhutanese government said its existing underground fuel storage tanks are not designed to handle ethanol-blended petrol. Experts warned that the ageing tanks are vulnerable to water seepage, which could compromise fuel quality because ethanol readily absorbs moisture.
