Mangalore Refinery and Petrochemicals Ltd plans to shut a 60,000 barrels per day (bpd) crude unit and some secondary units for maintenance from mid-April for about a month, a company source said.
MRPL, a subsidiary of the country's top explore Oil and Natural Gas Corp, operates a 300,000 bpd refinery in southern India.
"Apart from regular maintenance, we will be readying the units to hook up a gasoline treating unit towards the end of the year," this source said.
MRPL will be commissioning gasoline treating units to maximise production of Euro-VI compliant petrol.
India has set a target for a country-wide roll out of Euro VI compliant fuels from April 2020.
MRPL did not respond to Reuters email seeking comments.
