Magnetic swarf pickups in oil sumps aren't new, of course, but here's a novelty. I was led on to here from another site which mentions fastening a couple of old HD magnets to the oil filter.

I'm actually impressed by the amount of magnetic swarf picked up by a simple magnetic band pushed around the oil filter and even the application of it to a fuel filter makes sense, if there's swarf contamination in the fuel, but they just had to go and make a claim tooooo far...

"Impact 2. FilterMAG's sheer magnetic force destroys the single celled microbial infestations that can reside in the fuel-water interface because these cells are positively and negatively charged. The magnetic force kills them and rips them into sub atomic particles that pass through your injectors to be burnt with the fuel and then passed out as exhaust."
Frankly, I'm surprised they didn't go the whole hog and claim increased magnetic effect on the fuel molecules leading to better economy. But maybe they're hoping the customer will think that might be the case.
Help! I'm being ripped apart by magnets!
