The primary claim of TC-W3 oil as an additive is for lubricity. It also has high levels of detergents for cleaning, but I believe that's not an issue if you use a Top Tier gasoline. The study in that post makes it pretty clear that it is effective at significantly improving lubricity when added to diesel fuel and there is no reason that shouldn't apply to gasoline as well.
In my own use, I have seen no measurable gains in fuel economy, but that's not why I use it. I have also seen no negative effects of it's use.
