Comments from Blackstone Lab: Thanks for the notes. We compared your results to averages based on the 6800 miles on the oil, not the 10 months that the oil was in place. The oil in a modern engine wont go bad from just sitting in the engine- it's miles alone that count. Averages for this engine are based on 6800 miles on the oil
Wear metals in your sample are lower across the board which is agreat sign that the internal parts are in a helthy state of operation. The viscosity tested slightly thin,but that did not bother anything. The TBN of 1.7 is good(1.0 or less is low) Try 8K miles.
Edit: table added to increase readability
(Values should be)
SUS Viscosity @210 F: 52.8 - 55-62
cST Viscosity @100C : 8.13 - 8.8- 11.1
FLASHPOINT in F: :380 - >375
FUEL % : ANTIFREEZE%: 0.0 - 0.0
WATER % : 0.0 - INSOULUBLES: Trace - TBN: 1.7 - >1
This is my college daughters college car and miles are about 75% city 25% highway miles. It came with good service records when we bought it for her at 82K miles it and had always had NAPA conventional 5w30, so I just stick with that. Wife and I have another 09 Sonata as well and a Forester but decided to get a OA on this car since she drives more than we do. Anyway I tried to post the PDF file that Blackstone sent me but computer is not my expertise and I don't do spreadsheets and excel and such, so I just typed this out long hand ,copying the Blackstone test results. I could not get the pdf Blackstone results to copy over. Anyway Some rows are a bit crooked and the 3 rows of averages crunched together, but I did the best I could. I doubt if I will send for another OA for this vehicle but I am going to go to the 8K OCI next time as the Blackstone people recommended.
