Default Re: Engine Flush & Filter Magnets

If you've ever been inside an engine to do valve clearances or similar you'll note it's remarkably clean in there. Flushing oils can bring their own problems so again, unless there was a ton of sludge in there (in which case the engine's probably scrap anyway) I wouldn't want to use them. They're too thin to lubricate properly while the engine's running with them in, won't all be removed when you drain them out, can remove deposits which are actually sealing up gaskets etc on older engines, and they're unnecessary 99% of the time in a modern engine.

Magnetic sump plugs and similar certainly aren't going to do any harm, but I don't bother myself. Do buy quality oil filters & oil though!
