Ok, Going on info from another post, G4JSG is getting 45MPG on a long cruise, and 35MPG average. I've never got anywhere near 40MPG even on a long motorway cruise at 70mph. I average about 28mpg on my commute into work. My commute involves 8 miles of A road and 8 miles of motorway. I leave home at 6:50 in the am to avoid the traffic, so my drive in is not stop-start queing. It's not like I even drive fast, and the only time I boot it a bit is on the on-ramp onto the motorway. Could there be a problem? What is the general mpg for the 2.5 quattro? My car doesn't feel low on power or anything, and I had it serviced about 2000 miles ago.
