Agree to most everything. The oil is very sticky and very much unlike K&N oil but is purpose designed for a different environment.
I was only responding to the very broad comment, from another poster, that oiled foam filters are complete junk and a waste of money. That may be true in some cases but is not 100% true, also per my taking things a bit out of context in this thread.
The part I don't completely agree with is the "lucky to get 10k miles" part. That may be true for Polaris products, some of which go up in flames well before 10k miles, but I have plenty of friends who regularly use their "other" machines and are pushing 20k-30k miles on them. Certainly that is a far cry from on-road vehicles with reasonable expectations of up to 300k but those vehicles do not see the same sort of abuse either. Comes back to what they were designed for. :)
