My owners manual (2004 Honda Civic) indicates 10,000 miles OCI's and every other oil change to change the OIL filter (20,000 miles) NORMAL interval. Check your manual or the Honda web site to verify. This is of course with conventional oil!!!! So using M1 (synthetic) going the recommended (and also for warranty purposes) to me is almost a total no brainer
I also used the M1 (0w20) and will use the 5w20 when the 0w20 stash runs out in 80,000 miles.
Fram also makes the Honda oem filter. (to Honda's specifications of course)
I normally buy on price, so indeed FRAM filters (#7317) do cost more than the WM SuperTech 7317 so I buy them at 2.07 per.
