I have made biodiesel a few times from new soybean oil and have so far had no problems to speak of every thing comes out great when using NaOH as a catalyst. I am now starting to experiment with using WVO and I am having absolutely no luck every batch I make turns to gel. The oil that I am using has a ph level of 6.23 and only takes 1-2 drops to bring it to correct levels when titrating, I have tested for water and there is none… So what am I doing wrong are the FFA levels high enough to require acid treatment? And if not what are the normal levels that someone would use acid to treat his or her oil?

Very impressed... Teach them young. Smart kid. Going to email to everyone on my list.

That's odd. I've used oil that titrated up to 15 mL before with absolutely no problems when employing the acid catalyzed method. What is the exact procedure that you are using?
