Point number 5 is the one for which I expect the most criticism and disagreement.

Yeah, well, Larry, what do you know?? (sound like anyone we know??)
I've often thought about the store brands. If an individual was religious about oil changes every 3K and used a store brand for all oil changes, I'd be curious if he would suffer any measurable engine wear as compared to Castrol or Valvoline or any other name brand that you might choose.
My gut feeling is that oil is basically oil and that the name brands have different, and greater, additive packages to allow the oil to perform it's job for a longer period. However, 3K is not a long period (for most typical driving conditions) and the store brands might do the same job.
...........not that I intend to test the theory, however.
