wow I got that a little bit wrong, My Toledo wich is an 1.6 takes that much.
1.8 leon I do not really know, but don't think there is much different since it is smaller and stuff.
I drove 600km~ one day average 120km/h~ had to fuel up 38 liters, full it is 45 liters.
Seat Leon 1.8 maybe?
I have an toledo and it is really reliable, kind of good looking to imo and really cheap!.
my eats about 6.5liters per 100km. img1 img2
yes Leon got different rear, and I think that is the only thing different about them.
