Consumers are unlikely to get the option of choosing between pure petrol, E10 and E20 at fuel stations because maintaining separate nationwide fuel supply chains

Consumers are unlikely to get the option of choosing between pure petrol, E10 and E20 at fuel stations because maintaining separate nationwide fuel supply chains would be logistically complex, economically inefficient and unnecessary, the Ministry of Petroleum and Natural Gas said on Friday. The ministry maintained that E20 is a cleaner, technologically superior fuel, backed by extensive testing and industry support. “E20 offers a significantly higher octane rating, superior anti-knock characteristics, faster combustion, better pickup, smoother acceleration and cleaner engine operation. It produces negligible particulate emissions and reduces lifecycle carbon emissions by around 40%,” the ministry said in a statement. “In short, it is a cleaner, higher-quality and more efficient fuel than either E10 or pure petrol,” it added. Transition planned with automakers Quick answers to key questions • 5 QUESTIONS 1 Why won't consumers have the option of choosing between pure petrol, E10, and E20 at fuel stations? ⌵ The Ministry of Petroleum stated that maintaining separate fuel supply chains for pure petrol, E10, and E20 is logistically complex and economically inefficient, making it unnecessary. 2 What are the benefits of using E20 fuel over E10 or pure petrol? ⌵ E20 offers a higher octane rating, better anti-knock characteristics, smoother acceleration, and produces significantly lower emissions compared to E10 and pure petrol.

3 How does the transition to E20 fuel address concerns about older vehicles? ⌵ The government consulted with automakers and experts to ensure compatibility, resulting in almost all manufacturers honoring warranties for vehicles using E20 after extensive testing. 4 Will using E20 fuel affect vehicle mileage, and if so, to what extent? ⌵ Some vehicles may experience a 3-5% reduction in fuel efficiency when using E20, but the Ministry argues that mileage is only one aspect of overall performance. 5 Why is the Indian government promoting E20 as part of its energy strategy? ⌵ E20 is as it reduces crude oil imports, supports domestic ethanol production, and enhances energy security while being environmentally friendly due to lower emissions. Responding to concerns over the lack of consumer choice and the compatibility of older vehicles with E20 fuel, the ministry said the transition to higher ethanol blending was planned in consultation with automobile manufacturers, component suppliers, testing agencies and research institutions. According to the ministry, automakers were brought on board during the rollout of E10 as early as 2020-21, with India achieving its target of 10% ethanol blending in petrol in June 2022, five months ahead of schedule. For E20, the government said an even more rigorous process was followed.
