The last time I had my oil changed, 8330 miles with 5120 miles on the oil, I sent in a sample to Blackstone. They said that they were seeing a bit higher than average wear content, but that it was likely due to engine break-in. They also indicated that I should be fine going 7500 miles between changes. I plan on getting my next oil change at 15,000 and I'll take another sample at that time as well. I'm using Penzoil Ultra Full Synthetic.
