Unhappy Looking for 335 N54 Oil tests

Has anyone had their 335 N54 engine oil tested ?

I have had three oil changes (3200, 3000, 3000).
The aluminum ppm is still 8.5 times higher than the average.

820 miles (by sdiver68) 9 ppm
1500 miles (by 533ogetom) 14 ppm
3200 miles (Alan(iX)) 23 ppm
3000 miles on oil (6200 on car by Alan(iX) 22 ppm
3000 miles on oil (9200 on car by Alan(iX) 17 ppm

The average is based on a 6000 mile oil change, which makes my last value 34 ppm.

Aluminum is found in pistons, bearings, cases (heads & blocks).
The aluminum is still excessive, one would think that the engine is broken in at 9200 miles.

im curious myself as to testing it. Im due up for a change again soon (4k miles...yeah I know I change it every 3k) so I might send mine out. I dont really beat on mine, maybe that might make a difference?

I would like to see if other 335 N54 engines are observing this high aluminum content.
