Hello! and a question... water?

[andrin]

Hi, just joined the board and think this is really awesome. I'm not very savvy regarding fuel economy. I drive a Toyota Matrix (average 24 mpg) and a Honda CB750 motorcycle (average 50 mpg)

I do have a question, and not sure how to find possible discussions on the board as I amstill learning to navigate it. I've seen on the web ads for a device that somehow uses water and claims to increase mpg significantly. Anyone know about it... or refer me to place on board where already discussed..
thanks in advance... and once again, hello!
