This is the Wife's Armada. Right column is the GTX sample and most recent was the HPS sample. GTX run had 4600 miles on it and the HPS run had 8800 on it. What are your suggestions from folks who have more experience looking at these reports? Looks to me like I could run the GTX out to maybe 6K and I could take the HPS to 9K. They called out the AL but it isn't nearly as high as I've seen in UOA of other engine manufacturers. Since the wear metals weren't really higher with the HPS but it was a significantly longer run, it seems I could run that to 9K and be fine...or do you guys recommend a different oil? 7500 miles is the RCI for this motor but I don't see being able to get there with conventional motor oils.
Both runs were with a fram tough guard filter. It has a Mobil 1 filter on it for this run because I found a local place to get them finally.
