Hello, figured I'd post this UOA on my 2016 Ford F150 5.0 with a Roush supercharger.
During this run I was using Amsoil SS 5w-30 with 10oz of Liqui-Moly MOS2. This run consisted of approximately 4000 miles of hard street driving (approx 6 months), several 1/4th miles runs, over the road engine tuning, and several dyno pulls. The vehicle is a stock F150 with the 5.0 coyote V8 with a Roush stage 2 supercharger (75mm pulley) and custom engine calibration from a 3rd party tuner. Everything else is stock. On the dyno it made 540whp and 544 torque and runs high 11's on the 1/4th. During this interval I used several cycles of fuel injector cleaners and a round of Royal Purple octane booster.
I performed the analysis as I was having vapor lock issues over the summer and thought I possibly had a stuck or leaking fuel injector and was worried about fuel dilution (hence the injector cleaners). However cutting a hole in my hood solved the vapor lock issues (less heat) and fuel dilution is not an issue according to the analysis so I'm no longer thinking it was a leaking injector and I am no longer worrying about it.
The engine stock calls for 5w-20, but with 50% more power on tap I upped the viscosity. Its currently filled back up with 5w-30 SS, but will likely be switching to something a bit thicker, possibly the new Mobil 1 ESP 0w-40 or maybe even Redline 5w-30, based on statements Roush and Whipple have begun recommending 5w-50 as specced for track pack mustangs and other high performance Fords in future supercharger kits. I don't think I need anything that thick, but a little extra cushion for an estimated 650 crank horsepower isn't a bad thing, and the 5w-30 SS seemed to sheer a tiny bit.
My Amsoil preferred membership expired so no more Amsoil, and I won't be doing extended drains on this truck so don't really need the Amsoil SS.
Hope you all enjoy!

" Thanks for the detailed notes. We have universal averages for a supercharged Coyote engine.
They are on the far right, based on oil run about 6,800 miles. Metals in this report are mostly below
average, which is exactly what you want to find given miles on the oil. You can actually see the fuel and oil
additives in this report. A lot of the molybdenum is from the MOS2 additive, and manganese is from the
octane booster product. That's fine, and neither element is masking internal wear from the engine. Have fun
and just check back next service. Looks good!"

I would run M1 0w40 if you are switching to that brand considering you are in Texas and have the Supercharger on your vehicle. I would try without the MOS2 for a couple of runs as well if you intend to do a UOA.
I'm not a fan of adding anything to a carefully balanced oil. JMO.
