pinkaardvark said:So if you used standard unused vegoil say in purchased in 20L Barrels for a pound from Lidl's you could effectively just pour it straigh in?
Can you get 20l for £1???
If so it would be worth chucking in 20 or 40l of new oil, and topping up the other 20l with normal diesel, full tank for £22ish and a good mix so no problems with viscocity or anything too??
