This is my last comment to you on this thread.
I've used both commercially availible oils in both my Galants. In my personal experience AMSoil far outperforms Mobil One both in filter performance and oil performance.
I'm not basing my statements in direct opposition to you.
Its not my fault Mobil downgraded their regularly availible oil. At present I won't use anything else but AMSoil. Just remember that comes from using both in two Galants for a combined mileage exceeding 150,000 miles.
I don't give lip service to something I can't honestly support. Just get over the fact that I dislike the performance of Mobil in my cars.
