I can get almost anything in good volume, whats the general consensus among you all that have been burning oil in ur rigs on which waste oil makes the best fuel. WMO, hydro oil, gear oil, atf, is one better than the other. I’ve heard additives are bad synthetic is bad wmo is bad cause of carbon etc etc etc but I also hear all of it being used as it all obviously burns well, buuuuut is one better than the others?????
