May have contaminated WVO - Diesel Forum

Hi All,

I have been collecting WVO from various restaurants in my area for about a month and a half now and have about 300 plus gallons stored. My processor is on order and i hope to be running on BIO in a couple weeks. My question is how do i test the oil for contaminates. I picked up today from a new location and the oil is much darker then anywhere else i pick up from almost black like motor oil. I do not want to put this WVO in my 600 gallon storage tank and ruin the oil i do have. What can i do to test it? I am going to seperate it from my other WVO but would hate to get rid of a 100 plus gallons.

By the way what do you think about my oil collection trailer?

Darker oil is not necessarily contaminated. It was just in the fryer longer than the lighter oils were.

I mist wash all my oil just to deal with contaminants I may not even know as being present

Do a titration and see what youre dealing with, after that it doesnt really matter whats in there if it tests good. I made the mistake of bringing home about 40 gallons of wvo from a thai restaruant which titrated at 48!!!! It smelled like vomit and garbage, a nice combo of the two, totally worthless oil unless your running a wvo conversion on your truck. This oil was nice and golden brown, I just figured it was ok. You may want to test your oil out first, before doing anymore collecting just so you dont waste time and effort.
