I have been blending for a couple of years using a derivitive of DSE's formula. (85% wvo, 10% kerosene, 5% rug, diesel kleen, naptha, acetone) Part of their warning was to NOT use any oil used to fry meats. I acquired 10 gallons of peanut oil used to cook turkey for Thanksgiving. It looks really clean with no settlings in the bottom. Will the fat still be dissolved after all this time? Can I use this in my blend or am I asking for trouble?

If you set it outside tonight and it goes to a liquid then it is fine.
If it is solid then I would definitely not use it.
