Costcos Kirkland motor oil, produced by Warren, is also the manufacturer behind the oil for Amazon and Walmart's Supertech brand. It complies with the current API standards for motor oil. Generally, it performs comparably to most other synthetic oils unless your vehicle has specific requirements or is heavily modified.
You can safely use 5w-30 oil in vehicles designed for 5w20 or 0w20. The 20 weight oils are primarily aimed at meeting Corporate Average Fuel Economy (CAFE) standards rather than optimizing engine longevity. However, it's advisable not to use a 20 weight oil in a car originally designed for 30 weight oil.

The 2GR-FSE in my GS 350 uses ~6.8qt. Somehow I manage by buying 1x5Qt and 2x1Qt. Easier? It's objectively easier and less time consuming to pour 1x5Qt than 5x1Qt lol.
Sometimes I go crazy and buy multiple 5Qt jugs on sale. 3x5Qt = 15Qt. And I need 13.6Qt for two oil changes. Then I use a previous 1Qt bottle to measure out the remaining 1.8Qt. Much less plastic waste with 5Qt, as others have correctly pointed out.

True. I recently bought some Mobil 1 ESP 5W-30 to put in my 2011 GS 350. 5+2Qt. I used a Sharpie to mark off the full level on the 1qt bottle. It was much easier to see the level with a flashlight pointed in through the top of the bottle. Now I'll be able to more easily reuse 1Qt bottle, and fill it correctly.

It was worth it to me to pay a little extra and have the little bottles around as well.
Edit:
Last week when they weren't on sale I happen to see the 1qt bottles in a business center store. I didn't take note of what oil weight or how many in the case or the price though. Just know they can be found locally if you have a business center near you.
