Funny the first thing my google popped up was this
Fuel saving gadgets - a professional engineer's view
Which was bashing fuel line magnets
the second one was this
Looking For A Miracle: We Test Automotive 'Fuel Savers' - Popular Mechanics
again bashing it
The third link was wikipedia!
Why didn't you change the article to aid your argument?
The fourth is the Federal Trade commision
again not a positive light.
So how many links did it take you to support your claim?
