If it meets the spec, regardless of the name on the bottle, it's good enough.
Conventional oils often perform as well as their synthetic counterparts, depending on application, and in some cases, outperform.
I don't get offended any more when someone cries out that I should not perform a 10.00 oil change on my 2016 PowerStroke. In fact, I kind of chuckle now when the UOA shows all is well, and my lovely spouse and I had a nice dinner with the other 90.00 .
