I get around 460 miles to a full tank and that's only on the motorway journeys to my gf house which is 344 miles away from mine.but it is all motorway and good main roads.from full to half full I have gotten 250 miles.pics to prove.these cars aren't hard to run.thats if you stick to speed limits and don't hold your foot down on the throttle.mind you it is hard as I've got a full induction kit and cat back system and it really makes that 6 cylinder sound beautiful :-))
