Looks like the race gas had lead in it to me. Terry should be able to tell for sure. Looks great other than the lead. Like Terrys format for his lab reports!
Yes, I think the "unleaded race gas" pushes the limits on the allowable amount of lead in unleaded fuel. That particular UOA had seen quite a bit of Sunoco GT100 "unleaded" and Cam2 "unleaded". Right now I'm running Sunoco GT 104 "unleaded"-
and I'm using BC 5w40 just because I had a case of it.
Yes, I like his set up also, he types in quite a bit of analysis to the right of the raw numbers.
Next cycle I think I won't use any race gas. It will be mid-winter and I won't be using it as much and I'll get a "clean" sample using just normal unleaded fuel.
