magnetic oil drain bolt?

[scooby_si]

I recall seeing a while back in scooby land talk of sticking a very small but powerful magnet by oil filter which in theory wood then  attract tiny metal bits in oil to keep it cleaner....
See a magnetic oil drain bolt on ebay for mazda & wondered if anyone had any thoughts on these?

anyone, i\'ve asked elsewhere where you can get the tiny but strong magnets from as i cant remember now it was that long ago i first read about it & probably cheaper than the bolts themselves but any thoughts folks?

my sump bolt is magnetic, i thought they all were?

Last time the oil was changed (just after running in new engine) you could notice very small metallic content on the drain plug so i guess they must work to some extent. :cool

anyone else confirm that so i dont waste £10+ on sumin i already have?

Yep - standard ones should be magnetic.  My old RX-2\'s was and it was a 1972 model!

.ps If you have lots of metal particles, you are in trouble already  it really is the oil filters job - hence change the filter when you change the oil.

it was more like fine metallic powder than swarf. Understandable for a new engine, next oil change will be a lot cleaner i\'m sure.
