Yes it could be... maybe/maybe not. But your point is correct and well taken, I shouldn't just say "ABC oil is good for ### miles" as a blanket statement. For some reason I assume people follow the owner's manual maintenance intervals for normal service vs severe service (or the OLM), which as we know is not always the case. I don't think it matters whether the oil used is regular or long-life, the actual use of the vehicle / driving habits should determine the service intervals. And I would not use 7.5k mile service intervals if my driving habits qualified as severe service.
