Maybe the aftermarket will come out with a toilet paper roll air filter to match the toilet paper roll oil cleaner! 100% efficiency from the get go! No air movement, and no oil movement. If you don't run a paper filter, the next best thing would be an old style oil bath filter/cleaner. Or, like I jokingly said earlier, a KN prefilter on your paper filter. That gauze with oil really doesn't do much if you check the studies done so far. That guy joking about the pantyhose earlier would probably be better off using that.
