Any users & any problems. I have a 3year old Renault Master I was thinking of using it in.
so long as you make it properly, no problems at all
as above. I used it in a '06 megane dci 130, chipped to 160. Went very well indeed and got a few extra mpg too.

I know nothing about your van - just make sure your engine can handle it. As far as Im aware common rail diesels cant run on it it. If you can run it, be sure to change your fuel filter after a tank or two.
I've run it occasionally but with diesel prices at the minute I'm not overly concerned, also I wasn't sure that the garage near me stocking it was selling particularly refined bio. Feels slightly less rougher in the engine but gives the impression of extra torque. Might just be psychological.
