No one knows, it may not. But it can't hurt to remove any free floating ferrous metal.I’m not certain how much difference they make in engine oil, but they catch a tiny amount of that very fine debris.
So, they’re doing something.
Question is: does that make a difference?
On aircooled engines with no filter, i can't see how removing ( especially on initial startup) it is not helping reduce wear.
Pics of my magnetic dipstick, from my Honda powered pressure washer. From initial start, after 2 hrs or so.
Anyone think it would be better to leave that amount of iron in the oil?
