Hi can anyone tell me if my merc c class classi cdi 200 diesel 2005 reg will run on bio fuel thats manufactured or filtered.

I need to find a way to cut my running costs as fuel in the uk is cosyting me a mortgage of money to be able to carry on my trade.

I was thinking of a gas conversion after my 3 year manufacturer warranty was up but im not sure if it will help me do the same miles per tank.

All i want to find is a solution to maximise my profit rather than putting it back in the fuel tank and i dont know whichway to go.

Can any one advise me and help me make my mind up which way to go?
