Seems weird yung mga nakakuha ng 7-8 km/l for their I10 AT kasi estimate ko for the AT is 10-12 km/l city driving with heavy to moderate traffic.

Though I have an MT 1.1 I10, I never went down below 11 km/l city driving, my best is 18 km/l and average right now is around 14-15 km/l city driving.

Maybe the owners are either

1) Racing the engine
2) Fully loading the car
3) Tires are not properly inflated
4) Travelling short distances
5) Bumper-bumper traffic all the time.
