I bought the 1.6 Gli in the last week of Nov 2011 and have done 32000 km so far. I travel between Pindi and Islamabad. My average was barely 10km/l however I tried to follow the EconoMeter and was able to get up tp 15 km/l, but that meant not going above 60kph and not accelerating.
I was able to reach Lahore in one Tank via the Motor Way, where I drove at 140-150kph, but on the return journey via the GT Road, I was able to reach in just half the tank, driving at 90-100 kph.
I have tried to direct my driver to drive the car more carefully but he's hardly been able to get it above 11km/l. These are off course summer timings, with the A/C. I would also recommend that you reset your ECU after 3 months, by disconnecting the battery wire for an hour or so and cleaning your Air Filter regularly as well as keeping the tyre pressure at 30psi.
