I suppose the way to prove (or disprove) this theory would be to push the
engine to the limit, first with 8 and then with 12 quarts of oil on board,
and see if it overheats more quickly with less oil on board.

I suggest we try that with one of *your* engines first...

I think John Deakin of Avwebs Pelican Perch did this but in the opposite
direction...

He had an engine in his plane that was due for an overhaul. I don't
remember the situation, but he was willing to destroy it for the
information. Anyway, it was an Continental IO-550 or a -520 that normally
uses 8 to 10 quarts in the sump. He ran it on 2. He ran it hard. Not
only did the engine not self-destruct, he didn't even see an increase in
oil temperature.

I thought he wrote about this in one of his Pelican Perch articals, but I
can't seem to find it.
