I went to a cooling seminar at Oshkosh ... oops, Airventure.

The guy went on talking about heat rejection.  I started thinking about
our nifty little oil pan.  Here's a tip that I would like someone
to try:

1) remove your oil pan, and have it sand blasted to remove all of the
paint and to lightly texture the surface.  Have you seen Lycomings
cylinders?  All of their fins are rough and unpainted so that they
can more easily reject heat.

2) Go get some barbeque grill flat black paint if you can find
some that is compatible with aluminum and paint your pan.  This
will be "almost as good" as any commercial heat rejection
paint that you could buy.  The trick is that your primer
is important too.  If you can't find a paint that will work 
without a primer, just leave it bare and see if your oil temperatures
come down.
