Guwahati Refinery solely supplied smokeless fuel to Indian Army during Ops Sindoor: Official

Guwahati Refinery provided 19,000 metric tonnes of smokeless fuel to the Indian Army during Operation Sindoor, showcasing national pride.

The Guwahati Refinery, owned by Indian Oil Corporation (IOC), on Thursday (January 29, 2026) said it exclusively supplied 19 thousand metric tonnes (TMT) of smokeless fuel to the Indian armed forces during Operation Sindoor.

In an interaction with senior journalists, Guwahati Refinery (GR) executive director Sunil Kanti said the unit is one of the very few in the country which can produce Low Sulphur Low Aromatics SKO (LSLA SKO), and it was the sole unit to provide the specialised fuel to the army during Operation Sindoor.

“The Indian Army had requested us sometime back to produce a special fuel, which would not emit smoke. They wanted it to keep our soldiers warm in extreme cold conditions. Usually, all types of fuels emit smoke when they are burned,” he said.

Mr. Kanti said that the research and development wing of Guwahati Refinery then developed LSLA SKO for the armed forces stationed in high-altitude locations.

“During Operation Sindoor, only our refinery produced and supplied 19 TMT of LSLA SKO within record time. The product was transported to Misamari, Siliguri and Agra for further transportation to Army bases in cold border areas,” he added.

“From Misamari, the LSLA was sent to Arunachal Pradesh, while the product supplied to Siliguri was further transported to Sikkim,” the ED-cum-Refinery Head said.
