As you probably know Magnesium would help to offset but yeah still weird proportions on this old 90's formula.
OP: any idea why the high copper? How many miles on this Pathfinder?

116,xxx miles at the moment. 115,9xx when this sample was taken.

Only thing I could see being a contributing factor for the high copper, would be the fact my daily commute to work is 10 minutes tops, so the engine is rarely ever fully warmed up. And I drive it like a Maxima as I have a lead foot.

Thanks, That might explain it then.

Doesn’t bearing wear include copper and lead? This is just copper?

I would have thought so. My lead count is 7 when the national average is 5, but my copper is at 55 when the average is 5. Besides driving a cold engine like an ass as I often do, I don't know where else it could have came from.
