0W-20 is NOT REQUIRED but rather is recommened. You will also see words like Optimal used. Any oil that has the necessary duty specifications can be used. Be it 5W-20, 10W-30 etc. I would only use a full synethic oil.

Before my 5k I'll make sure they have 0W20W in stock or I'll bring some. All the oil I've seen of that weight anywhere is synthetic.

Non-synthetic may be better ....
The owner manual spec says Lexus recommends oil with a 0W-20 viscosity. However, it also recommends "An oil with a higher viscosity may be better suited if the vehicle is operated at high speeds, or under extreme load conditions". The dealer service manager I talked with said he would recommend a higher viscosity oil like 5W-30 if I plan to do lots of highway driving or pull a trailer. He further said a higher viscosity oil like 5W-30 should not be mixed in with the low viscosity 0W-20 oil unless its an emergency. So sounds like if I plan to take a long trip during the summer that involves lots of sustained high speed driving on the interstate, I may be better off with the higher viscosity 5W-30 oil. Your thoughts?

The Updated Maintenance Requirements for RX350 and RX450h indicates changing the oil and filter every 12 months or 10,000 miles which comes first. It says replace engine oil with 0W-20 oil. And the 10,000 interval goes all the way to 180 months or 150,000 miles. Thats 15 years!
