Did you reset the computer part way through your journey?
Zero'd before ignition. G46 7TH to G72 7RW via the M77/M8/M74 complex if you can be bothered with Googly Maps.
I've been hitting high 50s (57-58) for the past week or so and decided to drive like Miss Daisy today.
I think 65mpg is definitely achievable on a decent run with this car at circa 56mph.
The temptation to boot it is strong however - especially as my last car was an S500
Thats what I like about diesels.
None of this high consumption for ages while its warming up on the choke.
Although will that drop as the particulates start to build up ?
I read a lot of posts here with problem diesels.
It would be interesting to see how this compares with the actual consumption figures, using something like Fuelly. But it's not exactly a bad result whichever way you look at it!
I'd like my mpg to start with a '6', but I would have to do too much pushing to achieve it. Although I have managed a genuine 55mpg...
