Not knowing a whole lot about oil analysis reports, I'm surprised the aluminum amount isn't much higher.
Any idea how many engine hours you have on this oil? Generally 200 hours on mostly/all highway driving, or 100 hours on mostly/all city/stopngo driving are good targets to hit.

I look at the reports more like a watchdog than a reason to stretch my intervals. I average 15-18k miles a year and typically try to change oil every 5-6k miles. It's good to be able to look at data once or twice a year and quantify things like fuel dilution, solids, and water in the system to use as indicators to see if antifreeze or excessive fuel is starting to enter the system. Also how well the filters are functioning to keep the abrasives at bay.
Latest oil analysis for SHO attached. Mostly city driving but a few long trips. Also attached is latest Jeep one so you can see that Blackstone is helpful when issues arise. Jeep seems to have a head gasket or worse going on. Jane the Jeep is going to go under the knife soon for lots of old part changes.
Yea I have been using the amsoil filter. I may go back to motorcraft soon. My amsoil guy here keeps filters on hand for me essentially as his other clients don’t use that filter. I’ll keep look out for fuel in oil, at least injectors look easy to swap on this motor. Unfortunately there will be quite a bit of city driving until jeep is fixed, we put some mileage on the car. F Super Duty doesn’t fit so well in Old Town Alexandria.
Yea I have been using the the castrol hm for a while now on the Jeep. I started using it after I noticed issues with the possible coolant. I tried Mobil 1 at one time in Jeep but that was only for a 3,000 mile oil change.
Straight up amsoil in everything now besides Jeep differentials and transfer case.

This the first time you used LWSP? I would not use as a baseline if so, because that high detergency will clean off / out the gunk clinging to the gears and the inside of the case. Hopefully the next test will show significantly improved numbers.
If it is not the first change, then there might be something to look into. If you are up to it, take the diff cover off and take a good look inside.

Interesting. In the last 5k miles (Since April 2018) I have changed the fluid 3 times. Before that I don't know if it was ever changed before. Mileage was about 69k when I changed it the first time. I used Royal Purple 75w90.
Changed again in 3k for the first time with RLWSP. Then drove about 2k more, changed again. This sample is what came out after that low mileage duration first using RLWSP. I think the next test will be perhaps a better baseline.
