special-winter-grade-diesel

Context:

The first batch of special winter-grade diesel has been recently flagged off from Panipat Refinery to ladakh. 

About the fuel

  • It is the fuel designed to withstand extremely low temperatures during the winter months.
  • It is developed by Indian Oil Corporation (IOC) 
  • The new fuel designed also complies with BS-VI emission norms

Need for Special Fuel:

  • Fuel is developed for motorists as they face the problem of freezing diesel in their vehicles when winter temperatures reach - 30 deg Celsius in high-altitude sectors like Ladakh, Kargil, Kaza and Keylong.
  • Regular diesel fuel contains paraffin wax which is added for improving viscosity and lubrication. At low temperatures, the paraffin wax thickens or “gels” and hinders the flow of the fuel in the car engine.
  • Special types of diesel are thus used at low temperatures that contain additives enabling the fuel to remain fluid in such conditions.
