It works.
Size: 5 Quarts, Pack of 3
Ran this for 5k and did oil analysis. It performed identically to Mobil 1 ESP 5w30. No issues, stayed in grade, nothing negative. That said, it was no better than ESP and wear metals were functionally the same as multiple other similar rated oils. It’s perfectly fine, but not better. It’s a great value. I wouldn’t use it for extended oil change intervals. No oil consumption noted.
