So I'm on my third tank with TC-W3 and I really haven't noticed any difference in mpg, or anything else for that matter. I'm wondering if my first tank using it also happened to be the first tank of winter blend gas that went into my car this season.

I'll keep using the tc-w3 until my quart is empty. Once its gone, I should be able to tell if it was making a difference or not.
