Anyone have any data as to what affect mixing two stroke oil with auto fuel does to vapor pressure? Will it make auto fuel more tolerant at higher altitudes or less?

Since the oil is harder to vaporize it should reduce the tendance to vapor lock. I always get crossed up on vapor pressure, higher is harder to vaporize? I sure you get the idea.

PS the oil can reduce the octane level if mixed in high enough quantity although at the 100:1 needed for the rotary I doubt if you would even notice it's there. Bill
