Avgas has a lot of lead, lots of it. I could only get 19psi out of it without knock, where with the 100octane race gas that they sell at the pump I can get 22psi without knock.
Avgas will mess up your 02 sensor, heated or not.
Thats the conclusion I came to with my Avgas expirement.

The turboblue is 108 octane, I bought a drum of it last year. As for the Avgas, it isn't designed for cars and lacks certain lubricants. Much better off with the race fuel, I would use the 110 over the 100.
