I just wanted to post this up. My first UOA ever. I have pretty much always ran dino 5k ocis but tried PU for 9k. I filled it again with the same PU 5w30. This is the "old PU" without pureplus label on the bottle. The dealer recalled the pistons on this car and they replaced the pistons and rings at 118k miles. It has seemed to run just fine ever since even though it didn't seem like it ran bad before the recall anyways. Let me know what you think.
