It all came about the other day when I was sat in the pub. As I was sat there chatting to others, a man came into the pub delivering cooking oil to the kitchen. He came back from the kitchen with a drum of old cooking oil, it was at this point that I asked him what does he do with the waste oil??
So he told me………….. he then uttered the words Bio Diesel, this was when I really started to listen. It also turns out that his operation was only 2 miles from my home.
Anyway it turns out that he did two types of Bio Diesel. The first is just pure oil and second has a couple of additives for newer Diesel engines and winter running.
So I would suggest that you see if you can track down a supplier of Bio Diesel in your area and start saving a small fortune!!!
