Probably a bit anti-climatic but this was my recent oil analysis from Black Stone. This was 5w20 Mobil 1 oil with appx. 2,000 miles. I had a total of appx. 3200 miles on the car at sampling. Yes, I do have the tick. Please click the attachment below.
EDIT: The following is a response from Blackstone in regards to a question that I ask about what to look for in the oil sample if I was seeing excessive cylinder bore/piston wear. :
As far as poor piston/cylinder wear goes, that would show up in our tests as high aluminum/iron (respectively). Ferrous oxide is just rust off of steel, and that shouldn't really be an issue in a modern gasoline engine with how well sealed up they are. Really, we just test 20 of the base elements, so we wouldn't be able to tell if iron is from, say, a nanocrystalline-structured steel or just standard steel. When certain elements/metals show up together, that can help us pinpoint the source, but with so many steel parts in an engine is hard to be 100% sure where iron in oil analysis is coming from. Another thing to look for if piston scuffing is suspected are visible pieces of metal in the oil/filter. From what this first report showed for your Coyote, all looks good -- surprisingly good in fact, considering the low miles on the engine . Usually we find a lot more metals from wear-in in the second oil change, but your 5.0L is already nearly wearing like most do post-break-in. Please let me know if I haven't properly addressed your question, or if you have any other inquiries about your report.
