Dave,
When employed as a consultant to several OEs, I did some work on OLM systems. Even without knowing which yours actually is, I can tell you that it does not actually know the quality of the oil fill. They count on your using lube oil that meets at least their minimum requirements as listed in the owner's manual.
Some systems only count accumulated mileage. Some track other things like cold start count and total fuel consumed. I'm sure that they have gotten even smarter.
The smartest thing your did was go to Blackstone.
