I would think an ester synthetic 10W-40 would be good, but it's possible a 30 might work better. Neither will breakdown from excessive heat. I would think a 50 would compound the cooling issue.
Thoughts?

I bet I have covered your question in a pile of thoughts now...
the bottom line is Racer X is once again and in simple words right...
all that effort to cool down the combustion chamber with oil, water and air is just to protect mostly the exhaust valves from overheating and melting which take most of that heat and for longer than the rest of the chamber...
