I have one of these on one of my cherokees - a frantz oil filter. It is literally a roll of toilet paper as the element, but it's not paper I'd want anywhere near my bathroom, for fear that it got used. I think 1000 grit sandpaper would be more comfortable. The oil filter that the jeep was supposed to get is NLA, and the one that everyone tries to sell me rubs on the motor mount and leaks like a sieve as a result, so I have to use a cheesy FWD cadillac filter. The PO wasn't convinced that the caddy filter provided enough filtration. *shrug* To me, the toilet paper soaked in oil makes a great campfire starter in the desert. I'm looking forward to lighting off the one that got changed after the fuel pump diaphragm went and the pump started pumping gasoline in the oil :) K
