Hating Honda's fuel dilution. Wear numbers stink, especially by historical Honda-Toyota standards, where 1 ppm iron per 1,000 miles was almost expected.
0w40 is probably over-kill here, since it resulted in a 30 weight in the end, and this engine is spec'ed for 0w20.
Stick with the Xw30 option, as you're doing now with the Citgo 10w30 you're using now. Although M1 AFE 0w30 for your tough winters.
I can't say any adjustment you make will help those wear numbers though.
