Thank you to all who have responded, I enjoy learning from all of your opinions.
I have decided to go with synthetic oil, even though it will likely be recycled before it has reached the end of it's useful life. I've made this decision based on two factors; (a) should I not be able to change the oil in a short time frame, I'll have the cushion to keep going without feeling like I'm gambling with my engine, and (b) service records seem to make a difference in the value of this brand even at this age, and receipts showing maintenance that follows the manufacturers recommendation could make or break a sale.
If this were a vehicle that I was planning on running until the wheels fall off, I would not be uncomfortable using the PYB at 5k intervals, and it doesn't seem like anyone else would either, beyond "that's not what the factory recommends."
