I have a GLi 09. I'll share my fuel consumption averages (KM/L) with you guyz:
Highway (Gulshan to Port Qasim=7:30am) (AC=75%) : 14 - 15
Highway (Port Qasim to Gulshan=5:30pm) (AC=75%) : 13 - 13.5
City (Gulshan to Tariq Rd to Saddar and back) (AC=100%) : 9.5 - 10.5
- AVERAGE MILEAGE : between 12 - 12.5 KM/L On one full tank.
REMEMBER: You can increase your mileage by atleast 2KM/L by simply changing the way you drive your car. For further details about Economy Driving, just google it.
