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 5w-30 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)
Both great oils, IMO, and I have the same questions myself.
Here's a sample of the Schaeffer 9000 5w30 I used in an F150 (5.0) year before last. This was almost 10k, towing 5500# for 1500 miles and another 1500 miles of high speed through Wyoming at altitudes from 2300' all the way up to 7000'. I think that once I use the last of the Amsoil I bought for the 4Runner, I'll run the Schaeffer and compare UOAs.
