Good point on the calibration issue, that never occurred to me.
I do not know what the "short" means but since you asked, I'll call them back and ask about it. They are closed now but I'll report back tomorrow.
We discussed the iron, he said it indicates cylinder walls, and that it tracks with the mileage on the oil. So, the 13,000 vs. 8,000 is presumably why it went down. I didn't notice the fuel dilution so I'll ask about that too.
Not expensive: the oil analysis above is $20 US and the TBN is another $12.50 plus the cost to ship them the sample (I paid about $7 for that).
I asked the tech if they ever compare oil to oil (different brands) but I don't think he answered me. He did say that in Blackstone's opinion, Mobil1 is good.
Thank you as well!
