05 rrs been remapped 2.7tdv6 is it better to use better fuel?

I occasionally go through phases of using V power & Ultimate diesel on my remapped D3. Generally it is 10% increase in mpg and she runs a lot more smoothly. I tend to stop when I need to pay £1.50 plus per litre as it's only the more expensive garages that sell the stuff locally. I use Total good stuff on the continent as it's a lot cheaper & not much more than standard stuff.

£1.50+

I'm amazed of the gulf now between the real deal and the waste product! At £1.50, that's a whopping 21p PER LITRE more than I am getting petrol for around here. Would nag me at that price why I didn't buy a petrol in the first place (aside the extra cost).........cunning B s the Petrol Retail Assoc and the govt.......current glut of oil and prices per barrel now at $105 avg. (adjusted for the now split Brent / WTI dreamed up by some genius).
