YouTuber Saurav Joshi has retracted his earlier claim that E20 fuel was responsible for a sharp drop in fuel efficiency in his Mercedes-Benz SUV, saying the problem was actually traced to an engine-related fault. The clarification comes days after Mercedes-Benz India stated that all its BS VI petrol models are fully compatible with E20 fuel.In a recent post on X, the content maker said the car was inspected by an authorized Mercedes-Benz service center, where technicians identified an engine issue affecting the SUV’s mileage. He also apologized for the confusion caused by his earlier remarks, adding that he never intended to spread incorrect information or mislead people.The controversy started after the vlogger claimed in one of his videos that the fuel efficiency of his Mercedes-Benz GLC dropped from 17 kmpl to 5 kmpl within two days. He attributed the decline to ethanol-blended gasoline, saying that a full tank, which used to deliver about 800 km of driving range, now lasts only 490 km.Following the viral video, Mercedes-Benz India issued an official statement addressing the claims. The company reiterated that all its BS VI fuel vehicles are certified for E20 fuel compatibility and meet the required regulatory standards.“At Mercedes-Benz, customer safety, vehicle reliability and performance are of the utmost importance to us. All Mercedes-Benz petrol BS VI vehicles are materially compatible with E20 fuel and certified accordingly by the relevant authorities. We are happy to support customers for any technical questions. Mercedes-Benz remains committed to sustainable mobility,” the company said in its statement.
