Has anyone tryed running there diesel on hydraulic oil as fuel or a mix of diesel and hydraulic oil . I have quite large quantity of clean oil and as people seem to run there diesels on staight vegy oil from tescos It would seem a shame to dispose of it if I could Burn it in the Disco instead . I'm shore I'm not the only person with access to this sometimes waste product lets recycle it and depribe Gorden Brown of a bit more TAX!!
