How many 2011+ guys have switched to the amsoil ATM 10W-30? I need to change my oil here pretty soon and I'm thinking of making the switch to this. Is this oil alright to be driven durning winter months? We get down into the 20-30's at times in the winter. Also going to be pulling the converter out of my car to get it restalled so I'll probably change to the amsoil ATF too.
When looking at the viscosity curve, Amsoil ATM 10W-30 flows about the same as any off the shelf 5W-30. Your North Carolina winters should not be any problem.
If you have any worries, AZO 0W-30 has been proven to not shear in 500 rwhp Terminators.
