Petrol pumps in Guwahati will begin selling ethanol-blended E20 petrol from April 1, 2026, following a nationwide directive issued by the Ministry of Petroleum and Natural Gas. The mandate requires oil companies to supply petrol blended with up to 20 per cent ethanol and having a minimum Research Octane Number (RON) of 95 across all states and Union Territories.
The notification, dated February 17, makes the sale of E20 petrol compulsory, although limited flexibility has been allowed in special circumstances for specific regions.
From April 1, 2026, petrol pumps in Guwahati will sell E20 petrol containing up to 20% ethanol and a minimum RON of 95, as mandated by the Centre. The move aims to reduce crude oil imports, cut emissions and support farmers by increasing demand for sugarcane, maize and grain-based ethanol.
What Changes for Guwahati Fuel Consumers?
Fuel stations across Guwahati, including major corridors such as GS Road, Zoo Road, Maligaon and Beltola, are expected to transition to E20 petrol as per the directive.
E20 petrol contains up to 20 per cent ethanol blended with conventional petrol and must comply with Bureau of Indian Standards specifications.
Vehicle owners in Guwahati may need to check manufacturer compatibility, especially for older vehicles, although most newer vehicles are being designed to handle higher ethanol blends.
Why the Centre Is Introducing E20
According to the government, the move aims to:
- Reduce India’s dependence on crude oil imports
- Lower vehicular emissions
- Promote cleaner-burning fuel
- Support farmers by increasing demand for sugarcane, maize and grain
Ethanol is renewable and domestically produced, making it part of India’s broader energy transition strategy.
Flexibility for Certain Regions
The notification allows for exceptions in special circumstances for specific regions and limited durations.
However, no specific exemption has been announced for Assam or Guwahati at this stage.
Impact on Guwahati’s Air Quality
With Guwahati periodically recording elevated Air Quality Index (AQI) levels, cleaner-burning fuels such as ethanol blends may contribute to reducing emissions from vehicles over time.
However, the actual environmental impact will depend on vehicle compliance, fuel quality control and broader urban traffic management measures.
What Vehicle Owners Should Do
Motorists in Guwahati are advised to:
- Check vehicle manuals for E20 compatibility
- Follow updates from oil companies and authorised dealerships
- Monitor official advisories regarding fuel standards
Oil marketing companies are expected to update infrastructure and supply chains ahead of the April 1 rollout.
