I'm talking about magnets in oil drain plugs. I use them in my 3 toyotas for several years now and every time i change oil i write down the amount of magnetic fuzz (almost nothing/minimal/mild/moderate/severe).
I was going though my notes (that were not well organized) today and noticed (for the first time) that amount of metal correlates with type of oil. some Pennzoil products (PYB,PP,QSUD) and German Castrol gave the lowest metal wear, M1 and G-oil gave slightly more metal, followed by Maxlife synth, and the worse was QS Qadvanced.
I vaguely remember one of the oil companies advertising lower wear compared to M1. Does one remember which one it was?
