I can tell you I work for VW/Audi in the technical side for 15 years and we do not use a special formulation for break in oil. The high end Audi stuff comes new with full synthetic and the VW lines have either a full or semi-synthetic from the factory.I have no interest in the arguments on the topic, but I did want to ask about something as it seems you work in the industry vertical.
I've read/heard that new engines ship with particular special additives which assist in the breakin of the engine, and that changing the oil too early would prematurely remove that "break-in oil". What are your thoughts on that? Is that something restricted only to cars?
I think your question maybe manufacturer specific but my opinion is that really nobody that I know of still uses a special break-in formulation. I could be wrong though.
