bio Diesel

[Al]

Bruce,
Thanks for the vote of confidence. I have asked the two forums I
participate for their opinion on the matter. But I am with you on a
new truck with less than 10K miles. Somewhere it got bad or dirty
diesel fuel. Now that my trucks have run several tanks of fuel, my
fuel filter is clean. I still change it out monthly as a
preventative measure.
Just to spend a moment to discuss how biodiesel is make at the
homebrew level. I have a diagram that plainly illastrates the
process of making biodiesel:

Hopefully this helps to clear up how to make bio-diesel to meet ASTM
fuel standards.
