Just joined tonight and took a while to read myself in . I drive a MY11 SD4, as I note some of you do, and from new I have filled up with BP Ultimate, so I can't comment on smooooothness of the engne or improved MPG. Ran my last car on Tesco diesel for 95000 miles. I moved over to BP Ultimate because of the dreaded DPF. I have a friend who works in the diesel industry in Germany and he gave me a detailed presentation (over a few beers) on how they work. His advise, amongst things like avoiding lots of short trips etc was to use the best fuel available to help prevent DPF problems. Whether or not it works I don't know as I haven't done a controlled experiement and used the cheap stuff (relative term). BUT, 8500 miles later and toooooo many short trips and DPF is fine.

If I was running a pre DPF model I would still be burning Tesco crap.
