I've used 0w-20 and 5w-20 for slightly better fuel economy. You can also use 5w-30 in the Texas heat for high speed driving without any ill effects. Toyota and Lexus now use 0w-20 in that engine so the choice is yours.
One thing to watch out for is the water pump at this mileage. If you notice a drop in coolant, inspect the pump as it's probably leaking due to the acidity that builds up in the coolant. Right now is a good time to drain, refill with distilled water, run the engine, drain and refill with Toyota OEM coolant to get rid of any acidity that may have been built up which is corrosive to this pump. My ES350 started leaking at 57k miles and My RX350 at 70k miles.
Thinking of PMing my WP when I change the coolant at 100K
