I won't dispute any of that for a second.
What you are saying is that the old oils were "good enough". That's totally fine to say. It doesn't acknowledge changing and emerging technologies and constraints that will put different stresses on the oil, nor does it mean there is no room for improvement. Thus, it doesn't bear on the question of whether Pennzoil's cleanliness claims are valid.

Do you know what the difference is?
I am not saying anything about new or old oils The problem is lack of proper oil changes/maintenance. I can tell the marketing difference with out any problems.
