I would say go stock up on Pennzoil Platinum at Advance Auto's BOGO sale ... or the QS TorquePower BOGO + $15 off 5 quarts. Run it 10k+ and don't worry about UOA at that milage.
I'd say, with your annual mileage, that whether you choose a dino/semi/full synth will depend on how often you want to change it. By the factory numbers you're looking at 4 OCIs per year. Seeing as you're way out of common bounds ..that can stretch, maybe, to 10k (3 times a years) ...but I imagine with a synth, backed up by at least one UOA ..maybe two, you could be down to a 6month OCI without too much trouble.
Now this would be a BOLD MOVE by BITOG standards...

TWBG, the M1 0w-20 could have very well contained Group III. I think XOM has been doing this for awhile. But I also believe that some grades are still all PAO like the 0w-40. I think it varies by the viscosity grade. I too liked the 0w-20 M1 in the Honda. I have the MC in now. Might try the PP 5w-20 also.
