I used to run my HDi on ASDA's finest, stuck a few tanks of vpower in it at one point and didn't notice any difference, so went back to the ASDA stuff. It's worth noting I did rag it everywhere though, it saw 3 figures for sustained periods daily, and was airborne at least twice a week. Used to get 42mpg from it too.
