Thanks Dennis. I will follow your leads and look at the data. I am not sure why I am reluctant to run a 40 weight in my dd, but for some reason I am. However, I am not too inclined to run energy saving 30's either... My dp is indeed cat.

Maybe I need to photo shop a 30 label onto tha amsoil 40 and call it good. Regardless, I will be doing factory oci for awhile even though my tune and parts have made the warranty requirements moot.
