I was just poking around on the JC Whitney website and came across something that made me curious. It's a magnetic fuel saver. There are two different ones, a regular one and a high-performance/commercial one. They both claim the same thing...to break up clustered fuel particles in the fuel lines using a magnetic field. They claim to increase fuel efficiency and reduce build-up in the engine due to unburned gas particles. They just install around the fuel line with what looks like a couple zip ties. It seemed ridiculous, but I read several customer reviews that claimed to have noticeable mileage gains. Although I'm still skeptical, I am intrigued. The regular one only runs for $22.99, so I'm tempted to try it. What do yall think about it??
