India has taken a big step towards clean mobility, with E20 petrol now becoming the standard fuel across the country from April 1, 2025. According to the new mandate, petrol pumps across the country are required to supply fuel blended with 20 percent ethanol.The directive issued earlier by the Ministry of Petroleum and Natural Gas applies to all states and union territories. Oil marketing companies have been directed to ensure that the fuel meets Bureau of Indian Standards (BIS) norms, so that the quality remains uniform across all regions. Here’s a quick look at the details related to this mandate and how it affects you.
What is E20 fuel and how does it affect your vehicle?
So, what exactly is E20 fuel? In simple words, it is petrol mixed with 20 percent ethanol. Ethanol is a biofuel made from crops like sugarcane, corn and other grains. It burns cleaner than pure petrol and has a higher octane value. While the octane rating of regular petrol in India is usually around 91 to 92 RON, E20 fuel comes with a minimum 95 RON rating. This high octane helps in spontaneous combustion.
For car owners, the impact depends on the vehicle. Most new cars sold in India, especially those manufactured in the last few years, are already designed to be compatible with E20 fuel. Automakers are updating engines and fuel systems to handle higher ethanol blends, ensuring performance and reliability remain unaffected.For older vehicles, the government and manufacturers have said that E20 can still be used. However, there may be a slight drop in fuel efficiency in some cases. However, higher octane ratings can also help the engine run smoother under certain conditions.The bigger picture behind this change goes beyond just vehicles. The move aims to reduce India’s dependence on imported crude oil, which is a major expense for the country. By increasing the use of domestically produced ethanol, the government hopes to save foreign exchange and improve energy security over time.
