Sorry to disappoint you, but no flaming from me! I am of the belief that motor oil, in general, is SO much better than in previous years that almost any oil, if changed regularly, will probably do its job very sucessfully. Some are better than others. Or, a better VALUE. Some don't actually live up to their advertising. Some are more expensive and justly so. Some are just more expensive. Kinda' like the cars and trucks we use to carry them around in... So, GO VALVOLINE!
