Not much too say, it's the classic oil, only thing I can note is that it came with the old packaging and all that, but it works great for my car and runs smooth and without noises or temps, good value, and fairly fast shipping, good thing I can find it on here because none of my local auto stores had it on stock.

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.
