Most seem to do low 20's around town. High 20's out of town.
But the V6 petrol is not one for the fuel conscious.
There are diesels for that.
I'd say the 2.5 you could live happily up to about 12'000mile and under daily.
The thing is its such a great smooth engine that you want to use it more and more. So you do.
Then you realise how much extra fuel it uses. But no one cares about that when you press the loud pedal.
I'd love to have it run on lpg becasue then you'd get the best out of both worlds.
Yes diesel's can be made with as much power. But they really lack that special something the Busso has.
