Y'all know I'm a sucker for experimenting with MPG in the CDTi engine, so this evening, seeing as I had only 15 miles range left, I brimmed the tank with BP ultimate diesel and set all my tyre pressures to 34PSI.
So far I've not seen a great increase in fuel economy - I took the car along the A14 roadworks just outside Cambridge, a total of 27 miles at an enforced 40 MPH and got an indicated 70.6 MPG over that distance. That's about normal.
Before anyone jumps in - I know it's only an indicated figure and not necessarily accurate but it's about what I usually get on that journey.
I'm about to take the Tourer on a bit of a road trip so will hopefully be able to report back as to whether it's made any difference by the time I've got some miles behind me.
