The "flunkie" behind the counter sold me something that was purple, which was either "cut" or a completely different brand. I got some locally in Norwalk. I plan to use Sunoco Purple when I get around to NHRA Stock as well.

Year ago I tried the "Blue" for a short time, couldn't find any advantage in my particular application, and went back to Purple.
