I gave up on titration 2years ago. I have a formula that I use that I developed for the Oil that I haul. I found from reading alot of Gov studys that If you use a little more than what is called for in titration that it will "push" the reaction forword to compleation. I had to change my "formula" just a little when I changed from NaOH to KOH, but other than that I don't titrate at all.

From what I have observed from other people's work I've found that most people use exactly what is called for, and without any extra KOH if there is even the least little bit of water in the oil they will get an incomplete reaction. This is also why I don't use an "appleseed" style processer. With my open style processer I can see what is happining and can add a little more KOH if I see an incomplete reaction. This way I can add more KOH [1/4 pound at a time] to force the reaction to completion.
