Is synthetic oil worth the premium price for a Honda Accord with 140,000 miles?

I've been relatively consistent with oil changes (between 3750 and 5000 miles) with conventional oil. The oil change place tries to talk me into high mileage or synthetic oil every time, which seems like it may be a scam.
Previous questions here mention using synthetic oil in passing, but nothing definitive that synthetic is better than conventional. Similarly, Google searches don't seem to reveal any scientific evidence for synthetic over conventional.
Do any manufacturers actually recommend synthetic over conventional? I would think that if it actually made a difference that manufacturers would recommend it.
