The E20 transition: fuel for debate
Mechanics in New Delhi are reporting a surge in vehicle maintenance issues, such as clogged fuel injectors and sensor failures, which they attribute to the nationwide rollout of E20 ethanol-blended petrol. While the government promotes the E20 program to enhance energy security and reduce import dependence, a lack of public empirical data has led to growing public concern regarding fuel efficiency and long-term vehicle health.
Why it matters
The transition to E20 fuel impacts millions of vehicle owners and raises critical questions about the balance between national energy policy and the practical, real-world maintenance costs for consumers.
“Business is brisk,” says 53-year-old Abdul Aziz, a mechanic and co-owner of a repair shop in Karol Bagh’s Nala market, New Delhi, a bustling car repair bazaar. He says this flashing a wry smile, his mouth stained red by paan . The surge in business, he says, is being driven by a growing number of owners arriving with strikingly similar complaints.
Over the past few months, motorists have been reporting a sharp drop in fuel efficiency and vehicles that jerk while driving. Mechanics call it “gaadi missing de rahi hai” — a symptom that often points to poor fuel delivery. According to Aziz and his business partner, Tanveer Ahmed Khan, the most common causes are clogged fuel injectors and blocked fuel filters.
