It meets the current API standards for motor oil.
Yes it works as well as most other synthetics out there unless you have some specific need/heavily modified vehicle.
Yes you can use 5w-30 in vehicles that call for 5w20 or 0w20. The 20 weight oils are for CAFE needs, not engine longevity. But its best to not use a 20 weight oil in a car that came with 30 weight when new.

I can't find any objective testing (e.g. test an oil every 2 years or something and see if the composition changes), but there are some anecdotes that very old oil (like 20+ years) can start to separate (usually heavy components in the bottom) and in that case to just shake it up.
Which leads me to what I wrote originally - don't buy enough oil for the next 20 years. I change oil in our vehicles combined maybe 5 times a year, so if I bought 10 jugs that would have me set for a couple years or so. That's enough that I'm comfortable knowing I'm saving some money, but not risking, for example, selling one of the cars in a year and the replacement uses a different grade of oil.

Odd that the 4 takes so little of oil. The older V6 takes like 5.8 (going from memory) quarts which is a bit of a pain with the 5 qt jugs.
I don't know how the newer Toyota 4's are for durability but the 4 in the RAV up to 2011 (or 2012) was renowned for using an entire quart of oil between changes starting at about 150k miles. The V6 of that time frame is regarded for going 400k or more miles without developing oil usage issues. I have 270k on mine and it doesn't use any oil.
I had a 2007 Camry (2az-fe) before the 2012 RAV4 (2ar-fe) and it needed a top up quart every month or so lol
