Hi all, I have a couple of quick questions. I have looked at the J2F site and can't find an exact answer to what I am looking for so I am turning to you all for some help or suggestions. I have a source of waste oil that will provide about 20 gal of oil per week. They are using soy oil and the virgin form of it produces very good fuel. They say that they change the oil once per week. The problem is that the used oil titrates at 12 to 15 mL. It doesn't matter what I do to it. I have just taken a sample and tested it, I have dewatered it and filtered it. It doesn't seem to matter it all titrates high. The color of the oil does not seem to be an indication as to the condition since some of it is light in color kind of has a reddish tint to it and some of it is very thick and black. But it all titrates the same. I am using the better titration method form J2F site by using 2 mL of oil and 20mL of iso alcohol. I have mixed a stock solution of NaOH by mixing 5g to 500mL of distilled water then diluting 5mL of this in 45mL of distilled water. I can't figure out what is going on and would appreciate any advice. The oil samples that I have been getting are out of an old nasty looking oil dumpster and I am beginning to think that may be the problem. Please let me know what you all think.
