I had this same problem years ago when I first came to Alaska. I moved here from Ca. I used to use Havoline oil back then. never had a problem with it in Ca., but when I got up here I began to have the same symptoms as the O.P. An older mechanic friend where I was working told me to switch oil, that the Havoline oil did that sometimes in Alaska. I switched to motorcraft oil and had no more problems. I can not explain it, but it is what happened, and cured my problem. I would not have believed it , if I had not seen the results.
