sorry it wasnt a tech at a mechanic shop. it was the amsoil representative that asked what i was gonna do with it. he basically said the the amsoil 5w-20 would hold up because of its aditive packages and that the coyote engine had very tight tolerances so he wouldnt recommend anything higher than maybe 5w-30 if i really wanted to put something else.
