i've tried a few different diesel sources, and finally decided on sainsburys city diesel. its the only fuel that got my jtd running very smooth, if i ever have to use anything else, there is a noticable difference in smoothness and power. it maybe just me, but for now thats what im sticking to. i also use it with millers diesel sport 4 as recommended by ABZ, awsome stuff, smoother, faster, more eager to rev, and better mpg.

im thinking of starting to mix in some 100% biofuel (B12 i think) in a ratio of 80:20 (fossil:bio) as im reading very good things about using biofuel (not whats made from chipfat!, the proper stuff).

anyways, enough off topic, looking forward to your feedback on the/any differences of v power ;)

Interesting, i've always avoided supermarket fuel thinking it was inferior, always stuck to main brands, shell in particular.

A bit late in the day this one, but I did some research in response to a similar thread on FF a few months ago and posted it on the New Panda site (possibly). Essentially I filled up with BP Ultimate diesel and Sainsbury's regular City Diesel. I filled up alternatively, so therefore, 1 tank Sainsbury's, followed by a tankful of BP Ultimate (I think it's called). There were six tankfuls over about 2100 miles. It wasn't exactly scientific but noted the type of driving, e.g. country, motorway, leisurely or commuting. I also noted the trip computer mileage and also worked it out on a calculator. The result was that the cheaper Sainsbury's diesel provided significantly better fuel mileage than the premium BP fuel. The difference was typically 5-8 mpg better for the cheap supermarket type. What the long term engine benefits would be I couldn't say, but apart from the fuel consumption I didn't notice any differences.
