I've always run mobil-1. My 2015 GT is going to get the same when it gets its first oil change this weekend. Just out of curiosity why are so many of you all running amsoil?

I'm an Amsoil dealer (though I do it for the discount, not the sales...actually, I've never made a sale). Anyway, Amsoil Signature here. My S550 gets nothing less.
