E20 fuel rollout triggers performance concerns among Bengaluru vehicle owners

Vehicle owners across Bengaluru have raised concerns about the performance impact of E20 petrol, which contains 20 percent ethanol, after the fuel became widely available at city petrol stations. Owners of two-wheelers and older passenger cars have reported a noticeable decline in mileage and engine responsiveness since switching to the ethanol-blended fuel variant.

The shift to E20 petrol, part of India's broader push toward cleaner fuel alternatives, has left many motorists worried about potential long-term damage to their engines and increased maintenance costs. Several vehicle owners have noted that their two-wheelers, in particular, have experienced reduced fuel efficiency compared to regular petrol, prompting concerns about the economic viability of the fuel switch.

Older vehicle models appear to be most affected by the transition, with owners reporting that their cars may require engine modifications or repairs to run optimally on E20 fuel. The ethanol-blended petrol is designed for newer vehicles with compatible fuel injection systems, but many older cars and two-wheelers on Bengaluru's roads were not engineered to accommodate the higher ethanol content.

Automotive experts have suggested that vehicle owners check their manufacturer's specifications to determine compatibility with E20 fuel. Meanwhile, the concerns raised by Bengaluru motorists highlight a broader challenge India faces in transitioning to alternative fuels while managing the needs of an aging vehicle fleet on its roads.
