My engine magnetic plug usually has a little fine metal debris at every oil change. Obviously oil filter gets the vast majority of it.When I changed my engine oil, I looked very careful for any flecks of metal, I even put a drop on hard white paper under bright light and magnifying glass. There was 0 detectable metal, and meatal that might be there, will not stick to a magnet, as it is not ferrous metal. At a reasonable price these plugs might be a good thing.
Yes.If I can ask in this thread, should I change the differential oils sooner that the book says?
Bet if you if you accumulated 2200 hard miles between Diff Fluid changes it wouldn’t look so good. LolI said in a post in this thread, that when I changed my diff oils, I would tell you what I found. AT 300 miles, I got to it. The fluid in both did not look as bad as I expected, so I guess that is a good thing. I let the fluid settle out, and had some sediment in both, but no water and no dark color in either.
