Not a whole lot of difference. I would go 05w/20 plenty thin.

Toyota recommends both 0W20 and 5W20 for the 5.7L and I was just looking for recommendations on which one to use and the best brand/type for this motor.

5w-20 conventional.
Synthetic is not required and there's no reason to run it unless you operate the vehicle in an extremely cold climate.

record low for Yellowstone park is -66F, so if you plan on being there in winter, Mobil 1 0w-20 might keep things safe, in the cold season, since it has the lowest cold flow temperature of just about anything out there. Summer record high is 116F in another spot...
Where I live in Wyoming see temperatures well below zero with wind chills at -30 and -40F. In the summer it can get in the 100's for a week, but is usually in the high 90's. Will using 0W20 in the summer be the best thing or should I use 0W20 in the winter and switch to 5W20 in the summer? My only worries with the 0W20 is that it is so thin that I worry about it draining completely out of the top end of the motor making for dry starts.

This is that part I guess I do not understand.
PP specifically claims superior high temperature protection (compared conventional oils in same grade?) As one post said, if the thermostat regulates the car temperature (no towing, etc) then the high temperature should not be an issue, then what are they saying?

Use 0W-20 year round.

Any parts that touch each other will have a drop of oil stuck between them even after all the rest drains down.

Okay. Usually it is one weight recommended for most everyone's use. That would probably be the 5W-20 I would assume. In extreme conditions( either hot or cold )they sometimes will give you another weight option as well. Guess that is the 0W-20 here.
If it were me I would run the 5W. Not sure on Toyota and what their oil spec requirements are for the new Tundra but my 1st choice of oil would be Royal Purple then Penzoil Platinum 2nd. If you want to run a conventional I say Valvoline or Castrol GTX.
Sorry about any misunderstanding. Thought you were asking about using a non recommended oil( ie the 0W ).

Both "0W20" and "5W20" are printed on oil cap of many new Toyotas as recommended oil grades.
