Well, it seems like magnets are the best thing of all those tested, so I'll still have my hopes for them. Too bad they didn't do any additives.

Did we read the same article?

MIRACLE MAGNETS
There are dozens of fuel-line magnets on the market. We tested two. They all make similar claims: substantial improvements in fuel economy, reduced emissions and increased horsepower.

According to the people selling these devices, as gasoline flows past the magnet, the magnetic field will "break apart clusters of fuel molecules so gas burns more efficiently." Problem: Gasoline molecules aren't magnetic, not at all. But wait, there's more. If the fuel line is steel, as many are, the lines of magnetic flux will follow the fuel line walls instead of passing through the fuel.

THE DYNO SAYS: As we suspected, neither device had any significant effect on performance or economy.

Yeah, same article, but the magnets did not start fires, kill hp, or kill mpgs like all the others did, therefore it is the best, and because it is cheap enough to do I still figure it is worth trying out.

buy some neo mags from mcmaster and try them. im not sure whether or not the ones they tested were or not. who cares, its only a few bucks though....

Yeah, my plan/argument exactly.

you guys do the magnet thing...please find a part of the fuel line that isnt steel. It cannot be steel. Steel will 'cancel out' all of the magnets forces no matter how powerful. Steel just acts as a total barrier.
