So largely mine has been doing well as of late. 140 miles to Wigan followed by wedding duties in Liverpool City centre saw 53 for the 300 miles of the weekend with ambient around 15, oddly it regenned as soon as I got to Wigan, but it must have been spotless as it had just done one last use. Long journeys seem to incite one.
I went to the peak District on Friday in rush hour m1, 20 odd ambient. 75 miles with lots of stop start traffic did 54 mpg, return leg with no traffic but lots of slow driving/passing cyclists/sightseeing saw 55.5, best yet, and it was in the twenties at one point such were the nuisance cyclists. Just passed 2500 miles here. That was large amounts of acc too.
Car went back to Peterborough vw today to sort out some delivery damage, which resulted in 54mpg at 18 ambient, and I played with a mk6 gtd mid way. I'm easily attaining 500 miles to a tank if I use motorways, and have managed over 50 litres on fill up with 35 indicated to go. Depressingly though, courtesy car is a 150 blue motion that had 6 miles on the clock, did a pretty effortless 60 coming home with a dpf regen at the end! Started at operating temp though but still..
