My post was an expression of my thoughts when I saw the filter cut in half. Since I am not an oil filter expert I had no intention of going into positive or negative territory with my post. Some of the replies were from inconsiderate folks that are quick to judgement with no facts to support their one or two word quips.
Your post was so general that it contributes nothing to a discussion. If you don't want to get snarky comments, maybe you should have elaborated on what your saw inside. Or posted a picture at least. What is completely empty? Was it a piece of cardboard? We don't know because you only provided an emotional reaction to something that has nothing to do with how you feel about it.
People make WAY too big a deal about oil filters and oil. Just change them regularly and you'll be ahead of the general public. Subaru sticks the blue filters on 300hp sti engines and some people with non-turbo cars obsess over filter media, metal end caps, oil analysis, and probably trade their car in before 100k.
