Reaching 1000 Kms

Last Saturday, I've reached 1000 Kms on my Odometer and I have computed my fuel consumption. I have fueled up 14.56 Liters of unleaded gasoline and I have reached 200 Kms before the fuel warning light flashes. So as we do the computation 200/14.56 = 13.73 Km/li. The fuel consumption improved and I'm happy for that. My next target will be 15km/li but sometimes I floored the accelerator to much and maybe some changes on my driving habits might help reaching my target consumption.
