Low CHTs and lead deposits on rings - any connection?

[AK4x4]

Gasoline octane is usually measured using the "motor" or "research" test method or an extension thereof. This produces a motor or research octane number for the tested fuel in "RON" or "MON" with the motor method being the more conservative and lower number producing test. The local gas station averages the two methods using the formula R+M/2. The octane rating of gasoline and long term storage stability, can be dramatically increased by adding tetraethyl lead (TEL).
I believe 100 Avgas "green" and 100LL Avgas "blue" share the same "Motor" class octane Rating(AKA aviation lean) of 100 and an 'Aviation Rich" rating of 130. The main difference between the fuels is the octane rating of the fuel base stock before the TEL is introduced, 100LL using a higher quality more refined base fuel and the amount of TEL added (100LL has about half the TEL of 100). The final octane rating of both products is the same "100/130".
The key to preventing unwanted lead buildup is heat. If combustion temps are high enough the lead remains in a vapor state and goes out the exhaust. If temps are too low the lead condenses as a solid on rings, plugs, valves etc. and leads to engine trouble. Good luck, Russ
