Previous UOA here.
148159 miles on the engine at the time of this sample.
For once, I don't think I have anything interesting to say about this OCI. All I did was drive the car. Average fuel economy is better than it has been for most of the time I've owned the car, so maybe I'm going easier on it.
I did have to top off about a week before changing the oil. That's gotta be part of why the numbers look so good.
