Army Chief Launches Indigenous Xtreme Weather Grade Diesel

General Dhiraj Seth, the Chief of the Army Staff, launched the indigenously developed Xtreme Weather Grade (XWG) Diesel in New Delhi on 31 July 2026. The fuel has been developed jointly by the Indian Army and Bharat Petroleum Corporation Limited for use in extreme climatic conditions.

Xtreme Weather Grade Diesel: Key Features

XWG Diesel is designed for combat and logistics vehicles operating in severe winter conditions. It functions at temperatures as low as minus 42 degrees Celsius and is intended to improve mobility, safety, and operational availability. The fuel can be used in the Indian Army’s existing vehicle fleet without modifications. It complies with BS-VI standards and IS 1460:2025 specifications.

Operational and Technical Context

Conventional diesel thickens in very low temperatures and can clog fuel filters. Such conditions have earlier created difficulties in vehicle operation in high-altitude and cold regions. XWG Diesel addresses these issues through a fuel formulation suited to extreme weather use. The Army has linked the fuel with improved mission reliability in cold terrain.

Development and Supply Chain

Bharat Petroleum Corporation Limited has established a supply chain for XWG Diesel from its Bina Refinery to strategic storage at Bathinda. The arrangement is intended to support timely availability at forward locations. The fuel was developed under a collaboration between the Indian Army and oil marketing companies. Its wider civilian use is relevant for high-altitude and severe winter regions.
