As much as I dislike M1 SM formula, I doubt that to be the case. Still funny as heck though. The SN appears to be a better formulation
All I know is what my boy told me. He is a service manger at the Chrysler Dealership, He said they had to call in for approval to do some engine work on a RAM 2500 with the 5.7 HEMI in it. And Chrysler would not honor the warranty because it had Mobil 1 in it. And I do know the guy with the RAM truck(small town) and he did have to pay out of his pocket to have the rear main seal replaced. To say the least he sold the truck.
Believe what you want.
Perhaps buddy ran the wrong grade of oil in the truck? Even then, they'd have to PROVE the oil caused the failure to deny warranty and would likely involve some legal legwork.
If the owners manual spec's a given grade of oil with an approval required, as long as the oil used carries that approval it doesn't matter who makes it.
