Vlogger Sourav Joshi claims E20 petrol dropped Mercedes mileage to 5 km/l

Sourav Joshi expressed concern over ethanol-blended fuel on social media, claiming it heavily reduced his car's fuel efficiency. Joshi stated that his Mercedes-Benz previously delivered a mileage of 16–17 km/l, but has plummeted to 5 km/l after using the newer E20 fuel mix. This comes amid wider consumer debates, though the central government maintains that E20 petrol only causes a minor 4% to 6% mileage drop in the long run.
