dieseldave:

AT  TDIclub forum, there is a thread about WVO filtering. This guy filters it like your supposed to, but adds 5 cups of baking soda to 45 gallons in a conical tank.

He then siphons the finished product off the top, and then drains the fat and gunk from the bottom of the conical tank. He has done this for 122,000miles on a 05 Jetta tdi and the engine is clean as a whistle inside.

I always thought that getting the glycerine and other impurities out meant having to use lye and methanol?!

Doug:
I own a 05 TDI jetta. The injection system is not suited to veg oil...

Tom:
DD, he is probably using the baking soda in the final wash to neutralize any remaining lye.

NoSpark:
To wash and filter WVO is exactly that, cleaning it up to burn straight. When you start using chemicals like methanol and lye to remove the glycerine you're making BIODIESEL. Seems some people may be confusing the two.

maxx123:
running a wvo boiler to heat the house. tried water filtering last summer  found that spraying water on top of the oil was the best ..if you stir it up too much you get white  crap that need to be unloaded in to the neighbors yard.

seems the water loves to grab onto  glycerin  and settle .
