Saying that, if they are overloading the filters with oil at the start then maybe he's not in the loop with what happens after a few 1000 miles when the oil starts to get pulled through the intakes.

So it makes me wonder whether you should clean all the excess oil off of brand new K&Ns right at the start? In fact, I think someone earlier in this thread said the same thing?
