The lube refinery, Lube India Ltd, was commissioned in 1969 with a capacity of 165 million tonnes per year of Lube Oil Base Stock (LOBS) production. Crude processing capacity increased to 3.5 million tonnes per year during 1969. In 1974, the Government of India took over Esso and Lube India by the Esso (Acquisition of Undertakings in India) Act 1974 and formed HPCL. Expansion of the fuels block was carried out by installing new 2 million tonnes per year crude units in 1985. A second expansion of Lube Refinery took place to increase the capacity of the refinery to 335 million tonnes per year, so far the largest in India. The installed capacity of the refinery was later enhanced to 6.5 million tonnes per year. The current installed capacity of the refinery is 9.5 million tonnes per year
