ive read all the comments long before i bought my i10, yet i still buy i10.
to my surprise, im lucky mine have good fc, now have been running nearly 20k mileage, i can get 14-15km/l.
and last time i went to kelantan from kl, only need to fill up rm50 for full tank, and still have extra fuel in tank,
and yes, im not a heavy footed, kept around the range of 90-120km/h only, 2.5-3.5k rpm only.

but i do know some i10 owners with not so good fc, im lucky i guess?
before my 1st service, the fc is around 11-12km/l only, it gets better after the 3rd service.
im using auto btw.
