XR-1 Oil additive, anyone have any experience?
 

I met a dude selling this stuff, I dismissed it as snake oil but have since come across it in many forums and haven't heard a bad word. Kinda like the whole seafoam thing I looked up (we actually can't get that seafoam stuff over in Oz and they wouldn't send me any when I contacted the company...but that's another story).

Anyway, anyone had any experience with XR-1?
