regular texaco derv. its the best quality fuel of all the brands IMO. i get a few more mpg's a tank than on supermarket fuel (watered down with biodiesel content)
it also depends alot on the petrol station itself, like how well maintained the tanks are, for example i know that my local shell garage regularly has problems with the tanks flooding, killed a set of points on my mini within 3 miles with the high water content.
i know a few people run on ultimate fuel, but i don't believe it is beneficial to an xud which relies on the sulphur content in diesel to lubricate the pump internals and injectors, ultimate derv has a lower sulphur content for modern high performance diesels (big german cars, jags etc) so not really of any benefit to a 20 year old idi engine
