new cookin oil from the likes of aldi/lidl and so one will go in and itll run fine on it,, probs seem to arrise from the dirty old chip shop oil that hasnt been filtered correctly... prob is the goverment sussed onto the new cookin oil thing pretty quick and hence the cookin oil aint much cheaper than noraml deisel now. i know of a few guys running 2.5tdis on bio with no issues AS YET !!!! ive done a lot of lookin in to this and it does seem to be 6 of one and half a dozen of the other,, . there are other alternatives but ill pm u the info lol
