I was reading the new Australian 4WD monthly and on the new products page there is this magnet that goes on your oil filter and collects all the little metal shards that are in your engine. I was wondering if anyone has ever tried one of these things and if they even help. Thanks. :)
There are two things that would incline me to say this is mostly hipe. One is that oil in the filter is moving at a pretty good clip most of the time. Too much turbulance to really catch anything. If trying to capture magnetic material I'm apt to believe the oil pan is your best bet. Once the engine is shut off a good magnet (neodymium or the like) can do a nice job of pulling iron from the oil. There are some aftermarket companies (I think one is called superplug.com) that sell them. The other thought is if the filter quality is A+ it will be capturing all the material capable of real damage without the help of a magnet.
That is what I thought but was just curious. Thanks for the help. :)
