    Well the principle is obvious, but I'd like to hear opinions on this from people out there that have actually used these.

    Some people reckon they are a harmless waste of money and your oil filter should suffice.

    But I suppose the proof would be whether or not folks using these actually have to clean a load of collected metal particles of it as part of their routine oil change.

    - One point made is that during the run-in period on a new engine there's plenty of dislodged metal filings etc. and that these are invaluable at that time? But can I assume that on my 100K+ miles engine that unless I am pouring contaminants in to it then these are well and truly gone?

    My old Renault 4 had a magnetic sump plug as standard.

    Every oil change involved a bit of a "hair cut" to the plug

    a number of cars used to have these. not sure about the modern stuff.
    the oil filter should catch the junk but it can do no harm to give it a hand.

    To be honest, the most useful function for a magnetic sump plug these days would be to retrieve the sump plug from the container you're collecting the used oil in, if you dropped it in accidently.

    Yup I have one too, having lost the previous sump-nut, I tend to wander off oblivious to everything around me when I'm on the phone, actually kicked away the original nut :o.

    Got one of the magnetic ones to replace it and a "hair-cut" is generally required at service time, nothing at all major or worrying but tiny shards present all the same.
