My theory is that if you have a diesel vehicle, with an excess fuel return (most diesels do) and can fit enough of these magnet things, you have to stop and drain the fuel tank every 100 miles or so because it will fill up. This is very inconvenient, as on a long journey, you can easily run out of jerry cans to drain the excess fuel into!
With one fitted to your engine, you'll notice that the exhaust will smell very strongly of bovine excrement.
