e9999, that web site is really great. I've spent some time reading many of the reports. As a trained scientist, I understand the ease with which a person can unconsciously introduce bias into his results without malice or intent to deceive. This can happen even to experienced scientists (global warming? anyone?). It is amazing to see the number of people who were convinced their device was doing something. Fuel heating, fuel cooling, fuel "catalyzing", fuel magnets, PVC injections, air/fuel mix alterations, fuel additives etc. Many of them were even granted U.S. Patents, only to be proven completely useless by simple, impartial testing.

The end result of all those tests performed by the EPA? CHANGE YOUR OIL!! Good quality, clean oil gave 3.6% better fuel economy. For most of us that's 0.5 MPG. Nothing else came even close to that.

I'll wait for numbers on this device before I decide.
