I collected a bunch of data on 12 oil filters for the 2001-present Duramax platform, and sharing for everyone else that has an interest. This is not meant as a "this is better than that" argument. Just a collection of data, across 12 filters, using money from my own pocket. All of these filters were opened new and unused. I still have all of the filters, so if there's any other measurements someone is interested in I should still be able to collect it.
