Well... it's been a week. I have to say there is a noticable difference. I don't have nearly the start up clatter and in particular the slow oil pressure build up when hot.
Based on my experience at least, to date, I would have to say the Fram TG3985 is superior in this regard. Glad I bought 2 right away. May have to stock up.
It just appears that the quality control on the Bosch is not up to snuff.
