Just changed the oil in my 72 MGB/GT.  Put in Casteroil 5/50W synthetic.
I've been running it in the engine now for quite a while.  My engine
has 120K, and when I started using the synthetic oil, it seemed that my
engine started running better.  Could be my imagination.  So, the shifting
now seems to be a bit smoother.  Could also be my imagination.

Oh, I live in Vancouver, WA, and it never gets much below 35.
