Done a journey of 337 total miles today to see family. Mid - Wales to Hertfordshire. Half a tank of regular Shell unleaded and the other half V-Power. With an average speed of 53mph I got an MPG reading of 40.7. Really impressed with it cant believe it was that good.

Probably about right depending on driving. My best from Oxford to Cardiff and back was 43.4 mpg. That was steady driving and with a stage 1 map.
