iv been running the terra on a mix of sunflower oil, diesel and a little unleaded as reading through the posts there seems to be a bit of conflicting advice and this seems a good mix of cheap and safe running, but the problem im now having is where to buy the veg oil from cheaply. i used to get 5l for£6 from asda(£1.20/l is good enough for me) but they have stopped doing these now, so where do you guys get yours from? if this is against forum rules for advertising or somthing then sorry n just let me know and il remove the thread.
