If people would actually drain the oil out at 15k miles, M1 would be worth it IMO. Instead they are running it 5k and expecting to see significant differences in wear vs conventional. Ain't gonna happen. If Amsoil 0w-20 doesn't hold up well for me at 10-12k, assumming I don't have to add much make up oil, I'm back to conventional at shorter intervals.
Well said buster
