I like the system one oil filter. Around here if you want a good oil filter you have to order it. There are several that make Hi Quality oil filters and for most the time thats what you get when you buy them. But we know there is always room for error,mistakes are made from time-time.So every time you replace one of those throw away oil filters with another,you have to hope you are not getting a defected filter that slipped past Quality Control.
