I'm here to report my experiences with Purolator oil filters. I have been running Purolator in my cars and trucks for years. Never once did I notice a problem. I use full synthetic oil (usually Valvoline), and change at 5000 miles. The oil seems just fine every time I change it. I have used fram, and did have problems. The last time I used a fram, I opened the box and the rubber gasket was broken. I looked, and sure enough, made in china. Well that makes sense. Every Purolator I have bought has been made in usa, and has always been in good condition. I only use the basic oil filters, not the $10+ ones. The other good ones are the OEM ones like motorcraft and AC Delco, but they are often nowhere to be found. I don't over think oil changes. Its a filter, it works, what more do I need? A few years ago I read that Purolator's were having a tearing issue, and this board made it seem very common. Since then, I have been cutting open every oil filter (I change it ever oil change). I have put on about 25,000 miles, so 5 oil changes. Every single one has come back in perfect condition. I even changed oil on my truck recently, and again, perfect. I cut open a fram once. It looked fine, but what really troubled me was the fiber end caps, if you could call them that. They were more of ragged, hexagon shaped cardboard. My 2 cents.
