I used the K&N for about 3 oil changes, liked the mpg's and did not have any issues with clogging up early but did find out that my silicon levels increased on UOA....I went back to stock filter and got much better silicon readings (same oil and driving mode) and did notice a drop in mpg's...went to the Amsoil drop in and am looking forward to results this test, so far I have similar results as K&N and it is not oiled.

I always made it my first purchase on the way home from buying a vehicle until now.
