Ethanol-Blended Petrol Sparks Debate Over Performance Impacts in India

Strategic Insights -

Veteran motorists and experts in India have expressed concerns about the introduction of ethanol-blended petrol, citing performance compromises, particularly for vehicles manufactured before 2023. Union Road Transport and Highways Minister Nitin Gadkari has dismissed these concerns, arguing that the 20 per cent ethanol blend is a major step towards cutting emissions, reducing crude oil imports, and supporting India's energy self-reliance.

The ethanol-blended petrol, E20, is a mix of 80 per cent conventional petrol and 20 per cent ethanol, typically derived from sugarcane, molasses, and agricultural waste. While it provides Indian farmers with an additional source of income and reduces stubble burning and rural pollution, experts have noticed that E20 works adequately in BS6-compliant vehicles but reduces mileage compared to pure petrol.

Key Takeaways:

  • E20 petrol, a mix of 80% conventional petrol and 20% ethanol, is being promoted as a major step towards cutting emissions, reducing crude oil imports, and supporting India's energy self-reliance.
  • Union Road Transport and Highways Minister Nitin Gadkari has dismissed concerns about ethanol-blended petrol, challenging critics to "show a single instance" of E20 fuel causing damage to cars.
  • Veteran motorists and experts have expressed concerns about the introduction of ethanol-blended petrol, citing performance compromises, particularly for vehicles manufactured before 2023.
  • E20 works adequately in BS6-compliant vehicles but reduces mileage compared to pure petrol.
  • Experts have noted that older BS2 and BS3 cars experience more severe problems, including sluggish performance, frequent carburettor tune-ups, and corrosion in petrol tanks.
  • Low mileage complaints are near-universal, according to workshop managers.

Statistics:

  • India imports 84% of its crude oil, at prices ranging from $40 to $120 per barrel, and produces only 16% domestically.
  • PSU petrol companies absorb losses when global crude prices rise, partly cushioned by government subsidies.
  • Ethanol blending reduces crude imports, lowers emissions, and supports rural incomes but is seen to impact vehicle performance.
  • E20 is blended at the refinery and supplied uniformly across PSU fuel stations for all grades of petrol – except the highest-performance petrol, such as 100-octane fuel.
