Am driving a 147 TS1.6 also...almost 2 years now.
I found that the consumption initially when new wasn't all that great. Could barely get 9km/l. It gradually got better after a few thousand kilometers.
My best ever was 11km/l which translates to about 660km per tank but was averaging mid 10s so 600km per tank was the norm.
Bear in mind that i'm in tiny Singapore which means its pretty much city driving all the time.
Now i'm getting low 9s (about 550kms before pumping) since changing to 17inch wheels and removing the pre-cats
...but its alright
Actually, if fuel consumption is a concern, why not pump half tank each time. Saves weight you know? Imagine if you were driving a GTA!
