As much as I hate to say it M1 makes a quality product. Everything they make is among the top performing products in the tier and at Walmart prices it's certainly affordable.
I just puked a bit in my mouth.
Haha You're post definitely made me crack up a bit! I've noticed in some of your other posts you don't seem to be really fond of Mobil oil, any particular reason or just because it's so commonly recommended?
I've personally used this High Mileage 10W40 quite extensively, but I wasn't quite expecting this formulation based off the earlier post of the H.M 5W30.

Given the 5W30 & 10W30 are rated API SL while the 5W20 & 10W40 are SN rated, the 10W40 formulation almost exclusively uses Calcium compared to the mix of Cal/Mag in the 5W30, over double the Boron, and a TBN of 12.6 vs 8.7. Given the 5W30 is a recent formulation while this VOA was conducted back in 2010, they're some interesting differences none the less.
