Brimmed the tank yesterday we did a100 miles before the needle went to full and after another 100 miles just under the halfway mark and decreasing rapidly. We did 43.7 mpg going up to Cardiff top down and 38.7 coming back with the top up all at between 68 and 72mph, the gauge is rubbish but the mpg as mentioned before very impressive. Don't quite understand the difference in mpg all the same as it should be the other way around surely......Em
