Vegetable Oil as Fuel

[Poodle]

I know this has been covered in detail on other forums, but i'd like to start a thread here anyway (3 reasons: - This site could do with some more useful content [no offense Matt :p] - Since buying an XUD i suddenly give a shit about VO - Finally, Foxy in his wisdom has deleted most of the useful relevant threads from .net since they're older than xx months :roll: )

I understand a lot of people use clean SVO in XUD's, but what about WVO? I realise it would have to be filtered, but surely the price difference is worth it..? And found this on ebay:

Any thoughts/input please?
