[T3] Notch Running hot.

[Keith Park]

Yea, I know, tape over the gauge...
I still have a thermocouple on that engine for head temps, when I get a
chance Ill look at that again... they were nearly constant at 315 in the
past, we'll have to see what they are now.

Keith, I want your numbers.  Synthetic holds heat more than conventional
and thus your oil temps will be higher.  Also, I really don't care about
oil temps any more.  I care about head temps and exhaust temps... they tell
the real story.
