Chief of the Army Staff General Dhiraj Seth today launched Xtreme Weather Grade (XWG) Diesel at the Manekshaw Centre, marking a significant advance in India’s defence logistics capability. Developed jointly by the Indian Army and Bharat Petroleum Corporation Limited (BPCL) along with other oil marketing companies within one year, the specialised fuel remains operational at temperatures as low as -42°C.

Conventional diesel tends to wax and gel in extreme cold, clogging filters and immobilising vehicles in high-altitude sectors. XWG Diesel overcomes this limitation while fully complying with BS-VI emission norms and IS 1460:2025 specifications. Critically, it requires no engine modifications or re-homologation, making it immediately compatible with the Army’s existing fleet of combat and logistics vehicles.
General Seth described the fuel as a game-changing indigenous innovation that enhances mobility, operational readiness and mission reliability. It eliminates hazardous earlier practices such as repeated engine starts through the night or the use of tank heaters, thereby improving both safety and the morale of troops deployed in the Himalayas. BPCL has established a supply chain from its Bina Refinery to strategic storage, ensuring availability at forward locations.
Beyond military use, the technology offers clear civilian benefits in high-altitude and severe winter regions of India, supporting reliable transport and equipment operation during harsh winters. The development aligns with the broader vision of Atmanirbhar Bharat by reducing dependence on specialised imported fuels.
Internationally, comparable arctic-grade diesels exist. Under Europe’s EN 590 standard, Class 4 polar diesel offers a cold filter plugging point near -44°C, while Russian arctic diesel is specified with pour points around -50°C for extreme northern conditions. Scandinavian refiners also supply polar grades rated to approximately -40°C. India’s XWG Diesel places the country among nations fielding purpose-designed extreme-cold fuels, tailored specifically for its unique high-altitude operational environment and produced entirely through domestic collaboration.
The launch underscores the growing synergy between the armed forces and Indian industry in delivering practical, high-impact solutions for demanding operational theatres.
