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.
