[V6-12v] fuel efficiency

[Jonathan]

Hey All,

Just worked out my fuel efficiency last fill up - just cause really. Anyway, it 
works out to be about 11.6L/100Km. It's official ecconomy is about 10 something 
isn't it?
Anyway, to my point. Is fuel economy a reasonable measure of how your engine 
is fairing? As in, that's not bad for a 13yr old engine that has done 
265000Km.

Car:
9 6A4
2.6 V6
5spd Auto, front wheel drive.

Cheers

Jon
