Just did a trip from Richmond to Nottingham on Tesco RON 99. stuck on A406 for 2 hours then the rest of the way smooth, mostly hover around 70 mph once on M1 (with exception of those road work 50 mph). I averaged 59.3mpg with air-con on 50% with fan speed 2 most of the way. this is with 2014 1.2 TSI DSG estate. im pretty happy with the figure.
