The entire concept of "proprietary" is junk because any major competitor can test various samples and decompose the base oils etc with little effort... TominNJ did this back in the day on M1 and started a $hit storm.
Having said that.. I still think Mobil makes top shelf products at very good Walmart prices. Just picked up several gallons of Super 5000 High Mileage (which is a blend) Probably Group II + III for $13.50... Tough to beat that Value.
