As a BMT UP driver I'm curious to know how better if at all the MPG is over a standard UP? My suspicions is that from reading the topics on MPG that the difference is minimum if at all. I know MPG is very variable according to journeys and driver style but in general are the Blue Motions ahead or am I right in suspecting there is virtually no difference? In my case I've so far travelled 2200 miles doing a 35 mile return commute on B roads with a few junctions, average MPG is 52. I'm a steady driver and change gear just after the indicator tells me.
