Nice results - those are sweet cars. My brother had one for a few years and I used to manage an Acura dealership back in the day. Very sweet engine noise from the drivers seat. Possibly the best exotic daily driver ever.

It's my understanding all Moly is not created equal. Something about tri-nuclear.
 
As usual, a good result from M1 0W-40. It's been my go to oil for every car I've owned, including my current rides (S2000 and NSX). This just makes me that much more confident in my decisions. I guess I should run a UOA on my own cars just for the fun of it.

The only thing I don't run M1 0W-40 in is my Expedition, but I'm thinking of moving it over just to keep life simple.

Yes, a little.
Wear obviously doesn't seem to be significantly increased.

Fuel mileage has been slowly dropping and I have an occasional hard start when warm, as well as slightly increased vibration at idle, so I suspect the fuel injectors need to be cleaned/balanced, which I plan to do soon.
