Agreed, changing back to dino oil will not hurt anything. Just switch back to the synthetic at the next recommended change interval, and all will be just fine.
Even if they had added dino oil to your synthetic, it would probably have been alright, you would just have to change at the next "Standard" change interval. I think that most synthetics are now compatable with normal oils, at least I KNOW that AMSOIL is and it has always been.
Take care and enjoy your ride. Oh, how many miles do you have on yours, and is it an '06 like mine? I haven't heard of any problems like that on the '06's, as yet.
