thats not good, A buddy of mine has been doing that, used oil, tranny fluid, some gasoline, lots of crap, all mixed up in an offroad tank. he runs it in his 2000 24v and it is ok, but after using it in his 04 it torched the engine, Pulled the injectors and they had so much build up on them it looked like dingleberries. never have seen that bad of buildup on any injector ever!! don't do it in the newer trucks they are picky
