Re: do these things really help mileage?
OK, I'll track down the white papers I was basing my statements on, and post 'em on my lunch brake.
And yes, you can go out and get 1000-4000 guass magnets (1000 gauss magnets are used in refridgerator doors), and attach them to the inbound fuel line for the same results. AGain, the closer to the delivery point, the better.
The fact that you can't find information, doesn't mean it doesn't exist. In fact, in my searching, I only found one skeptical perspective on water and fossil fuel magnetic treatment theories.
In the meantime, if you can give me references detailing why this 'crap' doesn't work, I would be most interested. You see, if neither of us can back our opinions, then the issue is moot, and jrogers is on his own!
