Hi all I am now ruuning on a mixture of diesel/veg oil The veg oil is working out at £1.00/litre, Its not the used stuff from chippies, Its straight from the bottle and is available from Tesco and all major stores,The beast is running quieter now and seems to be doing more mpg.I have a new fuel filter ready just in case it clogs up the old one, It does smell a little but i am more than happy with it . Did you know you are allowed to use 2500ltr of fuel before declaring it to the Taxman, If you are stopped by the dvla tell them you are running on a mixture of veg/diesel before they dip you, You are required to keep reciepts of veg oil purchased, happy motoring yall.
