I'm not sure that your namesake is offering good advice.
I have an Accord with the same engine a year newer than yours, and it has 144K at the moment.
This car has seen maybe two runs of dino in it's life, so I don't have direct experience with what could happen with a change to syn from conventional in this engine.
I did start using syn in our previously conventional oil '97 Accord at around 64K and had no problems, although the car was but six years old at the time.
I can tell you that my old BMW has lower consumption and no leaks on M1 15W-50, better than it has done on various dinos.
Our old Impreza also seems fine on PP, after a life-long diet of who knows what.
Synthetic oil is neither "very slippery" relative to dino, nor does it necessarily have higher detergency.
Hondas are usually pretty good at remaining oil-tight, as well, or at least the six we've had have been.
Try a syn in your car if you'd like to.
Ignore the old wive's tales about syn creating oil leaks where none existed before.
If you do find new leaks with a syn oil, you can always go back to dino.
