If you do get a small perforation in the media, how much harm can this be? The oil filters from the outer edge in, correct? Therefore, only the oil that gets through the tear is unfiltered, correct? The next time the same oil circulates through the filter it will probably get filtered. If so, I don't see what the big hoopla is over this, it is probably only a small amount we are talking about anyway. I am not saying that it is OK that the media tears and holes get in it, and it should be ignored, but just trying to understand how much harm may actually be done, if any.
