Try here they cover all aspects of making bio and using wvo. There is a video clip somewhere talking you through the process.

I think we are getting our wires crossed.
I make and run my truck on home made 100% bio - not wvo.
The OP was asking about home made bio.
Bio when made properly is safe to use - in comparrison with wvo.
- some forcourts now sell it at the pumps and macdonalds make there own for their HGVs.
the bio process removes all salts/water and returns PH back to near nutral
and the final voscosity of the fuel is similar to Dino -whereas filtering your own wvo from local chippy rarely addresses such matters - hence problems.

Oops didnt read the post carefully enough. I agree making your own bio is ultimately better for the reasons you stated and it can be used in most cars. But depending on the quality of feedstock you can still have problems with gelling in the winter and it can also be more aggressive and attack fuel pump seals and fuel lines ( unless they are viteon - I think that's the spelling). As regards ph values they can be reduced in wvo by water washing.

The main thing is that anyone thinking of using either method needs to do the research for themselves thoroughly as there is a lot of mis information out there. You just have to look on eBay where people are selling so called bio processors. Some of these are highly dangerous. So in the end people have to make choices on well researched info.
