my brother runs the Defender on straight veg oil the majortiy of the time, topping up with diesel everynow and then, thats what he was told to do on a land rover forum, the diesel just keeps the system sweet, and its worked fine so far.
however thats an N reg land rover opposed to an X(2000) transit. so not sure myself. i know there is thousands of topics on this matter but ive still never come to an answer. some people say its fine with a bosch pump others say you need a kit.
i just started thinking about it again since he done it on telly. telly never lies

I don't switch my lights on... I turn the dark OFF!
