Hey guys I changed my oil a week ago and just got the analysis back. I have done analysis since my first change every change to try to cover myself if I ever have a problem from piston slap or something with my 2002 6.0 liter. When I changed my oil there was some ferrous metal on the drain plug magnet that I have NEVER seen during any oil change on any of my vehicles. I looked like what you would see on the magnet when changing the trany fluid. Here is the result.

JASON: Copper has been reading quite high for your engine and it is an anomaly, something we don't
expect once wear-in has passed. The 5,084 miles you've run on this sample shouldn't be too long for this
type engine, so we think the continuing high copper and increased iron are due to poor wear at a bronze
bushing. If you found ferrous metal at the plug, we would bet there was non-ferrous with it. You may
want to consider cutting up an oil filter. The metals do not appear to be coming from bearings. The
excess wear was not caused by any contaminants.

What do you guys think about all of this? The truck has 20500 miles on it and my warranty runs out the end of this February. Do you think taking all of the oil reports into the dealer will get me anywhere or just laughed at?

I need to send mine it. I noticed what seemed like a good bit of fine, gray metal on my plug when I changed the miles after 5000 of 0W-40 Mobile one. The motor had a total of 8000 miles on it, the first 3000 being Dino. Hopefully this is just from the break in and I haven't seen this with my higher mileage 5.3.

Maybe we should move this thread to internal engine where Patman resides?

I have also been using Mobile 1 since 3000 miles.
