and now..... the 5 week update! Average Fuel economy is going up, 29.5 after about 400 miles, but keeps on going up. Engine seems to be loosening up a little too - had a chance to use 6th gear on a 40 mile motorway trip (longest trip to date), and it cruised well. Pity that the Sony player is so limited in features - its a bit "all fur coat, no knickers". Theres 4 seconds gap between tracks, it only scrolls the track info the once, the directory system works, but isnt particularly elegant. On the plus side, its belts out music with good bass and treble. Instruction manual turned up qui
