Thanks for providing a great education! "Comments" reads (consistent with what I thought I knew) "there's a lot of metal...from the break-in of new parts," that can seem "scary," but "is normal." I understood that, in the old days, cautious drivers changed oil after the first thousand miles to remove that metal to avoid internal abrasion.here is the UOA. It seems to be well worth it to change it out at 5k or even earlier.
But "Properties" reads "Insolubles %" "Should be" "<0.6 but sample is actually way below, at just "0.1."
Begs the question, "why change oil at 5,000 miles?" Is the level of dissolved metallic elements, eg., 29 ppm iron, problematic? Do the dissolved elements from left-over machining lubricants, eg. Silicon, impair the oil's viscosity and lubricating function?
Just a liberal arts major trying to understand. No war, holy or otherwise, intended.
