Hot Shot Secret FR3 Friction Reducer...anyone tried it?

I've had great luck with HSS Stiction Reducer, and their Diesel Extreme and EDT fuel additives....but I recently saw that now they make some new FR3 Friction Reducer additive. It's supposed to increase MPG, make things run smoother...etc, etc.

Has anyone tried this stuff? Snake oil? Or worth a try?

Just wondering.

Thanks!
