Based upon FrankN4's experience, I thought that the oil would do the engine no harm, particularly if I used it only during warm weather.
It is coming out after ~6K next weekend. Next up is M1 5W-30.
Subjectively, fuel consumption might be a little higher (30.2 mpg on the last tank, with several Sure is quiet, though!
I may have been right in using an oil a couple of grades thicker than the 5W-30 Honda recommended.
The car went back to 5W-30 after that and ran flawlessly for the next four years at which point my older son totaled it after falling asleep on the way home from work and running it into the back of a semi trailer.
The Accord was toast, of course but my son was okay. The airbags no doubt helped and when I saw the remains of the car, I was very thankful that my son had walked away from the accident.
Main thing I've learned here is that I'll more often err on the side of caution than I've run any oil to its potential mileage.
