I'm talking about using new veg oil - not used that will contain fats which may drop out as temperature drops.
Its clean (human consumption) and is lubricating
I can afford the diesel - but prefer to pay less tax - I pay enough as it is
I do understand that you will not want to go down this route - but many do run on it - some for the enviromental feel good - or like me - just to pay less tax
I can't be accused of being an enviromentalist - the wifes car only does around 25mpg on petrol
