Post Break-in oil changes - part II
Last Dec I posted an oil analysis report after changing my oil post break-in (e.g., 2000 miles) click here to view.
The gist of the original thread was that after a break-in period, metals in the oil will be expectedly higher as the engine parts find their groove. Subsequently, fresh oil after break-in is a good idea as it would remove unwanted debris and allow the engine to continue the break-in process sans high traces of metal particles.
Based on the first oil analysis report, it was recommended by Blackstone to keep oil change intervals short (~2K miles) for the first 10k miles of the engine's life; or until high metal counts leveled off.
For those that care to follow the health of a new engine post break-in, below is a Blackstone oil report from my second oil change where I logged another 2K miles on the oil (total of 4,400 on engine).
Should a responsible/**** owner change their oil after break-in and for a few more short intervals beyond? You be the judge....

It may take a while, but I'm anxious to see the reports at 10-12k.

The second 2k was about the same with a 1,200 mile & 500 road trip, the rest local stuff. The only real difference is that it took 9 months (Dec to Sep) to add the miles (e.g., lots of garage time).

The First column with '2,341, 4,395, 9/02/2010' is the mileage and date indicating the most recent oil sample and report. Each number represents the particles per million of the associated metal found in the oil. The higher the number, the more metal that is not being filtered. Too high of a number indicates a problem or an oil/filter system that is no long being effective.
The second column 'unit/location averages' is the average of each metal particle across all the oil samples that I have had performed on this motor; two in my case. Example: Aluminum - the first sample had a ppm of 8 and the second sample had a ppm of 5. The unit average thus is 6.5 rounded up to seven.
The third column with '2,054, 2,054, 12/04/2009' is the first sample I sent in and is not used for reference purposes and included in the Unit Average column.
The last column "universal averages" illustrates the average particle per million count across all oil samples Blackstone has received from similar flat six engines.
Ideally, once the car completes it's "break-in", I should see my oil samples begin to align with the universal averages.
Overall, the oil analysis is a useful tool to determine the optimum oil change interval and to serve as an early warning if trouble is brewing (e.g., a high nickle ppm may indicate a rod bearing).

Most of the first 2K miles were several 500-600 mile trips (shifting up/down gears constantly), along with a 300 mountain drive and about 500miles of local 20 min drives. The 2k miles were added to the car in about 3 months (Sep to Nov).
The second 2k was about the same with a 1,200 mile & 500 road trip, the rest local stuff. The only real difference is that it took 9 months (Dec to Sep) to add the miles (e.g., lots of garage time).

Break-in was by the book and it was a tortuous 3 months. At +2,000 miles I let her rip to 8K rpms (redline is 8.5K)!!!!
On a plus side and it could just be a coincidence, but the car has yet to use any oil between oil changes.
