Line Up and Wait
I have seen big variations.
For example nickel has gone down from 2.5ppm to 0.9mm and that is from a 29hr sample to a 46hr sample.
Obviously one should not complain but what could be the physical explanation?
Iron has also gone down by 1.5x, copper is inline with the oil age, chromium has gone from 5.5 to 3.2.
Assuming the metals get into the oil mainly from bearing / sliding surface wear (which is not an unreasonable assumption!) why do they vary so much?
