Does anyone know anything about the magnetic devices that fits over your fuel line. They supposedly increase gas milage and performance. Is this real science or just snake oil?
Here is a website for one one brand:

I also see from another website that the dealer profit margin is 400% or more. Ouch!

If it sounds to good to be true > It isn't !

crap. nuff said.

 

Snake oil (or parts?).

I've read studies that pretty much put this to rest. One study did hint that the idea might work a little if the ionization happened closer to the point of entry into the cylinder... but even then it's going to get swirled around in today's new cylinder head designs.

Plus, based on the design of the one on that page, it would seem they're using two magnets... probably a north pole facing a south pole. It can't be a real "Super Conductor" because we haven't yet invented super conductors that work at room temperature.

Good to great magnets are available cheaply over the internet.

From:
http://www.amasci.com/neodemo.html
"A 1/2" neodyimum disk magnet costs between $2 and $10."

http://www.fridgedoor.com/migstronmag8.html
"Incredibly strong neodymium magnet 8-pack. Each little magnet measures only .25” in diameter, but will amaze you with its strength. TT-001 $7.99"

But we also need to investigate the hydrocarbon linking claims. When they say that 'eventually' they congregate, are they talking over two or three months? I'm not going to do any more research on it, I'll leave that up to you to report back to us, but I hope I at least saved you $70 on the magnets...

 

Thanks to all who responded.
I think I'll hang on to my money.

 

Good deal! Save that cash!

err... no, that's the wrong attitude - we're truck enthusiasts, so we spend it on proven things we enjoy.

I don't remember the prices offhand, but I remember they were high.

I do also remember doing cursory searches for info, and a bunch of different engineers posting on some other board tore the neodymium-magnetized/aligned-fuel idea to shreds.

But... might I suggest an improvement I think few around here would argue with?

A multiple-spark, capacitive discharge MSD igniton (MSD-6A) would cost you just a tad more, it would give you more power (with regapped plugs) and/or it would create a better burn which would lead to better MPG.

 

You can always duct tape some cheap magnets to the fuel line to try it out, but I believe it would be a waste of time.

Now I did see a big magnet that goes on your oil filter, supposed to pick up metal particles, but a magnetic drain plug likely would be better.
