Wasn't the ester oil introduced after the engine already launched? That's why it's a TSB. Unless I'm wrong on that?

I don't understand your first question. Specific example of what? As to your second question, I don't know when the ester oil was introduced. To be clear, it's entirely possible that they're using ester oil for factory-fill. I just don't think we have 100% conclusive evidence one way or the other yet is all. And if we have to guess, I personally would lean towards guessing that they're not. But maybe I'm just more cynical than the rest of you.
