With this same engine being spec'd for 0w20 today, a slightly thin 0w30 or 5w30 after 10,000 miles isn't a big deal. As long as the oil did its job and there's still TBN left over at the end, I personally wouldn't hesitate doing 10k OCIs, esp if my Avalon sees a lot of highway miles...

Your call, of course, but I don't think highway miles will help you with this problem. It would help if there was fuel dilution, but that doesn't seem to be an issue. If you notice the report at 7k, the oil was just in grade, and by 10k, mine was not. I would rather run the oil grade specd for the car, esp for the timing chain. Other than that it was odd how close the reports were.
