I'm intrigued by Shaeffer's 9000 in 5w30, and all of the anti-wear additives it purports to contain. It claims to meet Dexos 1. Amsoil states it meets Gen 2. Amsoil has lower NOACK and higher TBN. While Amsoil's site IS marketing, it does at least document percentages of performance as compared to required certification tests, etc. Scaeffer's site is extremely general and vague in nature.
I'm wondering, in a 5w30 application not requiring Gen 2 (NA), and not utilizing extended OCI's, would Shaeffer's provide better wear protection than Amsoil under more severe driving, such as lots of towing?
Please just comment on this comparison/contrast...I obviously know there are other comparable oils at Walmart. (I don't see many S9000 UOAs to compare)
