Dear I got my Alto VXL on 1st October-2019. Put Rs.2500/- (22 liters) of petrol from Shell. The car was at 44Kms then. I drove till today on same fuel with AC On. Now the Odo is 313KMs (313-44= 269Kms). Today the fuel light is On and gauge shows the last bar left. I feel it will further give 15-20KMs roughly. Say for example if it gives 20KMs more then 269+20=289. Its is not good at all, it means mine is giving just13.13KM/L?? I also don't "kehnchofy" my car. I drive it with light foot by avoiding sudden speeding and braking. I also need to mention here that I live in Karachi and face heavy traffic jams especially on my way back to home (21KMs- one side).
Kindly advise me how to get best mileage/ maximum in per liter and should I fll the tank to fullest i.e. 27L or just put 22 Liters as I did 1st time?
