I tried to go a year on this oil and a Honda filter with top offs. 2004 Honda Accord 2.4 I4, mostly driven in the city, but had at least 7k of road trips on this oil. The last top off quart of oil was M1 10w30 because I didn't have anything else laying around. My goal was to just change my oil once a year in the Spring.

was a much longer oil run than you've used in the past and it might have been a little much for your Honda's engine. Iron (steel parts) read higher than we would expect, even after considering the long oil run. It should be closer to 15-20 ppm, but iron was a little elevated last time, so we're not ready to call this a problem. Your engine may
make more iron than average and that's okay. Maybe you did more idling over the winter, and since that's engine use that doesn't log miles, it could explain iron. The TBN was good at 3.2, but use 10K miles next.
