I second the opinion earlier of:
If you plan on keeping it longer than 100k miles, change it every 5k. If you'll trade it in before the loan is paid off or before it's out of warranty, who cares... do it as required to maintain warranty. (10k).
All Toyota cares about is that the car costs them no money while inside the warranty period. 10k oil changes will achieve this goal. However, I do believe and assert that the engine will degrade performance faster with 10k oil and filter changes vs. 5k oil changes, synthetic or otherwise. If this car spec' 0w-16, it will only be synthetic oil. I have yet to see a non synthetic 0w-16 on the shelf. If you are able to change your oil and filter yourself you will save a wheelbarrow full of money, but if this is not an option you could find a trusted person or shop to use the oil and filter you provide.
I would recommend Mobil 1 or Valvoline Full Synthetic in either weight. Mobil 1 is easier to find, especially in 0w-16. I have written this all not knowing what viscosity your engine specifies. Two trusted brands of motor oil that will provide peace of mind. Does this engine call for 16 or 20 weight? My apologies if I missed that information.
