I've vaguely heard of paper towel or toilet paper oil filters before. Seems like the military was using them even. But I just recently read a claim from a guy running a dodge cummins(i think it was) that he uses a frantz filter in addition to stock(as they are designed to do) and has clean looking oil. Is that possible? And even if not, what do you think about the system? Will it pull more trash out of the oil? Is it worthwhile?
