The government has clarified that fluctuations in vehicle fuel efficiency cannot be blamed solely on E20 petrol, noting that various elements impact actual mileage. According to the Petroleum Ministry, fuel economy is also influenced by factors such as traffic conditions, driving style, how well the vehicle is maintained, air conditioning use, and tyre pressure. The ministry stated that E20 fuel has been through rigorous testing and validation, and that real-world performance is ultimately determined by the vehicle's condition and how it is driven.
