OK guys read it and weep. After 6000 miles of towing with my custom install AMSOil remote bypass filters, (one factory filter in place and one remote filter and one bypass filter) below are the results. This sampling is better than the one 6000 miles ago with just two AMSOil remotes and running the MP8 on half the trip. Please read comments to me from Blackstone. At this point I will be running the oil for a total of 10,000 miles till next sampling.
