I just filled up £30 Diesel at Shell, Old Ford and reset the trip computer. I headed towards blackwall tunnel and was doing approx 40-45mph. Once it went to the 60mpg mark I had to slow down to about 30mph due to traffic which is when I started recording and you can see it still achieves 60mpg but is not going any higher. It would have gone up even more if I had more road to drive and less cars and sped upto about 40-50mph but then I had to get off and had to stop at traffic so obviously it started going down.
