I own Hyundai Verna Fluidic petrol which has clocked 3.2K Kms and its 2.5 months old. As much as I know Hyundai claims 17-18 Kmpl mileage for Hyundai Verna Fluidic petrol on highway so as per that I should minimum get around 14-15 Kmpl but I am just getting around 10 Kmpl on Highway. I also own an Aveo 1.4 which claims 13-14 Kmpl and I get around 11-12 Kmpl so that is fine. If I drive both the car that means my driving is perfect so in this case there is no question of driving sense issue also. So can you guys let me know what would be the problem? I even took my car to the service centre they did gscan and told me that there were no codes and they even did the mileage test and there also they found good mileage of around 18-19 Kmpl. So I am confused what would be the problem? Can anyone help me out?
