Excellent, detailed article on advantages of synthetic oil in November issue of AI magazine. :D

I read that article Monday night. The one thing I took from it was the whine in the trans could be from syn. I have been using syn3 in both holes since 1,000 miles (now have 9,000) and yesterday I decided to try sportrans again in the primary/trans. We'll see if that helps. I made sure I got the primary adjusted correctly also. I will report back.
