Right you are, customclipper55. The only way to tell for sure is to drop the oil pan and view the evidence. I'm copping out and running detergent, changing freqently, running my fingers through the drained oil (not fun) and hoping I'm doing some good.
The difficulty with oil types and fuel additive discussions is, the results all come down to "studies" with an insufficient "sample." We just have our own experience to go by, and the history of the engines, our driving habits, how often we change oil, and dozens of other "variables" enter the picture.
Unfortunately, nobody is running statistically valid studies for us. We're seat-of-the-pants on this, and that's why sharing information can be helpful, or sometimes just confusing, on issues like oil type and grade, fuel additives, what gas to buy, etc.
It's an ongoing mystery just what, exactly, is going on under the hood.
Body, interior, drivetrain and engine rebuild work are usually much more clearcut!
