Motorists in Bengaluru say the newly introduced E20 petrol blend is causing engine glitches and reduced fuel efficiency, prompting concerns among commuters.
Several vehicle owners in Bengaluru have reported abnormal engine behaviour after refuelling with the recently rolled‑out E20 petrol blend, which contains 20% ethanol. Drivers claim that the fuel is causing their engines to stutter and that they are experiencing a noticeable decline in mileage compared to previous petrol grades.
The complaints have been gathered by local consumer forums and shared on social media, where affected motorists describe the issue as persistent across different car models. While the exact technical cause has not been confirmed, users attribute the problem to the higher ethanol content in the new blend.
Authorities from the Karnataka State Pollution Control Board have acknowledged the reports and indicated that fuel quality checks are underway. They have urged consumers to report any further anomalies and assured that corrective measures will be taken if the fuel does not meet prescribed standards.
In the meantime, drivers are advised to monitor their vehicle performance closely and consider using fuel additives or consulting service centres if engine symptoms continue.
