In essence, I agree with Patman, why worry about the source and use a poor oil. WM's buyer will just go with the lowest bid next order.
However, while running a freezer test with the SL Pensoil 30 with moly for my father's 1973 Ford pickup( after reading this great forum and learning about moly) and just for fun, since I have that curious mind problem, I picked up a quart of the WM ST 5-30 oil for testing.
At that time, my 87 Pathfinder was using some serious oil, like 300 miles a quart, so it was a real candidate. After all, it is kind of interesting how cheap someone can make an oil that is still SL and GF3 rated. It indirectly tells something about SL/GF3,I fear.
Well, the WM ST 5-30 almost froze as solid as the Pensoil straight 30. In contrast, Mobil's SS 0w-30 seemed like water. I still have the ST unused and just decided to buy Pensoil 5-30 for $1.15 even for use in an old beater like the Pathfinder.
FYI, I have scheduled a Nissan reman engine next week. One advantage besides being cheaper that a new SUV, it that I get to play with a new engine with all that I have learned on this forum and try to make it last even longer that the last one.
