Hum. The Zinc and Phosphorus levels are higher than I've seen in other VOA's. And Mobil's published values are also lower. I think they claim 1100.
 
That stuff should work well on an old flat tappit 327 or 396 too.
I did a “Frankie blend” today with 1 quart of that FRAM 0w40 and 1 quart valve line euro 5w40 and auto zone 0w30. Went in friends 01’ dakota pickup with carquest premium 3614 variant
 
I run it for 5,000 miles in my motorcycle, 1200 cc inline 4. Works great, numerous UOA's in the motorcycle section. TBN after 5,000 MI was in the 6's so different lab, different samples means little.
