Top 10 fuel efficiency myths - MSN

[CTScott]

I have seen data on all of those proving that article correct.

The interesting one though is the link to the consumer protection site. I have been doing some consulting work for the past year for a company that has developed a product that installs in-line with the fuel system and pounds the fuel with high power electro-magentic pulses to break the long hydrocarbon chains into smaller, more combustible, sections. This product produces gains of 12-15% on diesel (and fuel oil based) systems and 8-12% on gasoline engines.

I have been testing one of their gasoline units on my completely stock 08 red Yaris for four months now and have been averaging a 10.5% increase in fuel economy. I have also done dyno testing on my Yaris with it, as many people claim (via the old butt dyno) that they notice a power increase with the device. My testing showed negligible gains with the device, but at the same time did not result in any loss of power with the gain in economy, which is good in its own right.
