Thanks for the reply. I do have some other questions then: aside from the RDV smell, how would I be able to tell if moisture has found it's way in? Or if it doesn't smell then I'm good to go? Also does Rancidity (is that a word?) eliminate the WVO from being fuel if it is passed though a water separator? Sorry if these are silly questions, I just hate to think that I am losing a couple hundred gallons of oil.
