I'm getting ready for the first change in my 2012 GT and I have already decided long ago I'm not going the 20wt route. I have used Amsoil 10/30 ATM in the past and it is a great oil and I am contemplating using it in the Mustang but I keep looking at the 0/30 AZO. I know on paper the ATM is the better. I just want to make sure on cold starts things get flowing as soon as possible. Opinions please.
Thanks, Swiftoy
