I haven't been able to figure out how to post the actual report so I'm just typing it in. I forgot to mention to Blackstone that I used 1/2 qt of Pennzoil YB to make up the full 6.5 qts.
Comments: We recommend taking a sample in mid-stream, because if you wait until the end, you might run out of oil(I had forgotten to have the sample bottle handy, so the sample came from the last of the drain). But we had plenty so the sampling technique was fine. All wear looks about the same in this sample, which is great considering you ran this oil more miles than the last. The only thing that was out of line was silicon. Silicon can have several sources in an engine, though we don't think it's dirt in your case because wear looks so good. It's probably from a sealer or lube. No moisture or fuel was present in this sample, and the air and oil filters are working.

I will be using this oil(Schaeffer's) for 2 more changes, approx 20K mi. Any comments on whether I should buy more of the same or save some $$ on another oil, would be appreciated.
