I sent in a sample to Blackstone on my truck and this is the report I got back today. I took the sample about 2.5 months ago and just got around to sending it in. I think what happened was I got my sample mixed up with my mother in laws sample that I took about 5 months ago. She has a 2012 Kia Optima turbo and was running dealer oil. She doesn't take great care of her car and she lives several hours away so I can't change her oil as often as it needs and she apparently won't take it in. Here's the results that got my heart pumping till I realized what I might (hopefully) have done. The sample I meant to send in of my truck has mostly highway miles. For reference, the first sample at 3880 miles was Mobil Super synthetic and the sample at 3945 miles is Pennzoil Platinum. This sample was supposed to also be Pennzoil Platinum but if it is indeed my mother in laws sample then its whatever her dealership uses.
