Thanks, Pat. The variable quality of oil filters has bothered me. At the oil change places, it's like Forrest Gump said about a box of chocolates..."You never know what you're gonna get." A few, however, like Pep Boys show the brand of oil filter they'll use (Penzoil). Best route for the best quality and most thorough job is to just buy the best components and do it yourself, if you can.
Yeah, I can understand your statement about shops prohibiting the use of customer-supplied items for any number of reasons. If you figure out which Consumer Reports article that might have been from, let me know, as I keep three years of back issues.
Thanks for your reply!
