Anybody ever use or heard of Auto RX?

Well I read about this all around the place and I decided to get some input from my fellow 240 guys and gals. Has anyone ever used this before? Try reading about it from this site, http://www.auto-rx.com/rms13/, it's from a 1993 Nissan 240 Hatch with a KA24DE and the before and after pictures and results look pretty good. However I've heard stories about how sludge tends to build up in cracks and if you use synthetic oils or some sort of engine flush it tends to open those cracks up and cause major oil burning or something along those lines. I was just wondering if this would be a good product to use on my 205,xxx stock KA24E.
