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.

Perfect fit

This product was a perfect fit on our 2009 BMW 328i. It was alittle difficult connecting the hose at the bottom because my husband has big hands but I was able to help tighten the screw Due to my smaller hand size Overall very good product and fast delivery
