How much does it cost to make your own biodiesel for fuel? Is it difficult?

Question

I've seen stories about the do-it-yourself kits to make your own biodiesel fuel. Are they expensive to start up or maintain? Is it difficult to produce your own biodiesel? Should I forget attempting this?

Answer 1

HOW THE HECK WOULD I KNOW!!!

Answer 2

I remember reading about a distillery you can buy, it was around £2000, and yes the chemicals involved if you try yourself are hard to get, you need knowledge of titration to make sure that you get the right fuel properties, and you must declare it (UK Government at least). All in all it's a bit long winded.

Just use pure vegetable oil, some manufacturers warrant this in thier cars.

The best one is a VW TDI engine (VW, Seat, Skoda and Audi - all modern diesels), all warranted for use with pure plant oil.
