AAP chief Arvind Kejriwal has raised alarms over E20 petrol, using a live demonstration by a mechanic to show how ethanol blending is damaging vehicle engines and reducing mileage.

Key Takeaways

  • E20 petrol is causing a significant drop in vehicle mileage.
  • BS3 and BS4 engines are facing carburetor and seal degradation.
  • BS6 vehicles are experiencing fuel pump and filter clogging issues.
  • The government has admitted a potential 2% to 6% drop in fuel efficiency.

During a 'National Town Hall Against E20' held at the Constitution Club of India, former Delhi CM Arvind Kejriwal launched a scathing attack on the central government's E20 fuel policy. Moving beyond political rhetoric, Kejriwal brought a professional motor mechanic onto the stage to provide a live demonstration of how ethanol-blended fuel is physically damaging vehicle components.

The mechanic, Aamir Khan, a veteran with 13 years of experience, showcased a carburetor and a fuel pump to illustrate the damage. He explained that the ethanol content in E20 petrol creates a gummy residue that clogs critical parts, a problem that was virtually non-existent with pure petrol.

Why This Matters

BozokMedia analysis shows that while ethanol blending is aimed at reducing oil imports, the lack of adequate transition for existing vehicle fleets could lead to a massive spike in maintenance costs for the common man.

"The ethanol-blended fuel is causing sludge to form in the fuel reserves, leading to engine failure in older models," noted the expert mechanic.

According to the demonstration, BS3 and BS4 vehicles are the most vulnerable. The ethanol causes a 'sludge-like' substance to form in the carburetor cap, which prevents the vehicle from starting if left idle. Meanwhile, even modern BS6 vehicles are not immune; their fuel pumps are frequently choking due to clogged filters, leading to poor pick-up and sudden engine stalling.

Crucially, the government has acknowledged in Parliament that E20 fuel can reduce fuel efficiency by 2% to 6% and that vehicles manufactured between 2005 and 2016 may face damage to rubber pipes, seals, and gaskets.

Did You Know?: Ethanol is hygroscopic, meaning it attracts moisture from the air, which can lead to water contamination in fuel tanks.

Frequently Asked Questions
