I've read several posts about the differences in air filters. The pro's and con's of oiled filtration vs dry. I had originally planned on the BHAF, but got tired of waiting for the local store to get it in for me, so I went with the Amsoil filter. I made an assumption that if it's Amsoil it would be oiled correctly and no problems would be found. I was out servicing the rig this morning and decided to look at the turbo inlet for signs of oil. YEH, it was there. My question is this. If I where to wash it and then apply the new oil, is there a rule of thumb as to when enough oil is enough? I'm just looking for some advice and not trying to start up another debate on filters. Thanks
