Techron is some kick butt stuff Brother I'll give ya that!
Sadly no Chevron stations around me. I read an article somewhere about the additives and Shell's V-Power was the closest runner to Techron. But even still, if I could, I would swing for the Chevron any day! I think I have a bottle of Chevron-Techron in the garage now.
