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!
Oil Filter Quality on 2006 Honda Civic
On oil filters. On Honda's I use a Honda oil filter, on a Toyota I use a Toyota filter. Nothing else. The engineers have designed flow and pressure valves in these things that the after market filter makers leave out. For example, anit-drain back valves on OEM filters keep the oil up in the engine. After market filters rarely have these, including Penzoil.
