Full tank, it depends. I can drive for a week with a full tank, maybe a little more. I'd say City maybe 400km, Highway about 450km and that's with the premium-guzzling smallport. The bigport is a different story as it takes regular fuel, I used to put abot 525km per tank with that one when I was doing strictly highway.
The smallport is being a gas guzzler lately, I know the Cat converter is clogged for sure, already have a Magnaflow ready to be put in, which of course I think is the main reason why my fuel consumption is so bad right now.
