First UOA post and wanted to do something different. I haven't seen any posts with both the UOA and the used filter cut open (doesn't mean there aren't any, just haven't seen it). I wanted to provide some information to let people make their own informed decisions about using synthetic or conventional, oil filters and how often to change the oil (miles and time).
