About Reference Fuels

  • Reference fuels (Gasoline and Diesel) are high-quality, premium products used for calibration and testing of vehicles in the automotive industry.
  • They play a crucial role in the development and assessment of vehicle engines, ensuring they perform well under various global climatic conditions.
  • Indian Oil Corporation Limited (IndianOil) has successfully initiated the production of Reference Gasoline and Diesel Fuels in India, a milestone for the automotive industry.
Purpose and Application:
  • Reference fuels are used in the calibration and testing of vehicles by automotive manufacturers, testing agencies like ICAT (International Centre for Automotive Technology), and ARAI (Automotive Research Association of India).
  • These fuels serve as standard benchmarks for assessing vehicle performance, emissions, and efficiency during development and testing phases.
  • The development of indigenously produced reference fuels reduces the need for importing such fuels from other countries.
Varieties and Sources:
  • IndianOil’s Paradip Refinery will produce Reference Gasoline Fuels in various ethanol blends (E0, E5, E10, E20, E85, and E100).
  • Panipat Refinery will be responsible for Reference Diesel Fuel production in B7 grade.
  • Previously, India sourced reference fuels from companies in Europe and the United States.


  • The local production of reference fuels by IndianOil complies with Automotive Industry Standard (AIS) specifications.
  • It ensures import substitution, reduces costs, and offers a shorter lead time for automotive manufacturers.
  • This development aligns with the Indian government’s initiatives to promote domestic manufacturing and self-sufficiency in critical sectors.

Importance of Reference Fuels:

  • Reference fuels are vital for automotive manufacturers to create engines and assess vehicle performance.
  • They are essential for guaranteeing that vehicles operate efficiently in different climatic conditions worldwide.
  • The development and usage of reference fuels are crucial for the automobile industry’s quality control, emissions testing, and technological advancements.
