Charlie: I'll ask bubba. What I can tell you is the chemical engineer in the family hasn't said to go out and buy some and treat the motor with it.

That being said my question would be, it costs X what is the increase, if any in milage and what it the increase in engine life if any, and what is the trade off.

I guess I'm just not a conspearacy theorist and find it hard to think that if REALLY worked it wouldn't be on the fringes of the industry and marketed through info-mercials.

My 2 cents.

I think that driving in a regular manner without sudden stops and jackrabbit starts and fast excelleration etc. wouldn't do more for longevity and fuel econemy than all the "miracles" in the world.

I could be wrong.
