Hey, if you want, I'd be glad to cut and post the filter in case stuff happens. Just letting you know and looks like good UOA

Wow looks good, almost 5800 miles and only 4 ppm iron wear with a retained TBN of 3.4 so lots of life left in the oil
 
That's an excellent uoa. I'll be curious to see how the M1 compares to it. I hope you do a uoa on it.

I had qualms in the '80s when I saw under the valve covers of engines that had run only QS oils. Sludgefest. The modern SOPUS stuff, however, is nice. I scored 5x 5qt jugs of it last year when it went on clearance at Advance Auto, both cars' engines were quiet with it in the crankcase (Toyota and Ford V6 engines). Probably will switch back when my current stash of Pennzoil Platinum High Mileage is used up...QS seems to have ~30ppm more moly on board based on PQIA and BITOG UOA data.
