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.

Instead Costco shoppers pick up other things beside this which would make this deal worth considering.

The better oil (~$26): ACEA C3 + some 2 or 3 more qualifications like MB 229.51 / BMW LL-04.
The base oil (~$22): ACEA C3.
The budget oil (~$18): API SN <-- This is the Kirkland.
It depends on how many miles you drive per year. For example, I drive 15,000 miles annually and require 3 oil changes. If I use 'The Ultimate Best Oil' instead of 'The Budget Oil,' it will cost me around $33 more per year theoretically (although there are often motor oil deals or promotions, so the actual cost is usually less than $33)
For me, I always choose 'The ultimate best oil' for any car I own, no matter how many miles I drive. It worth the price as it burns cleanly, performs better in the long run, and reduces wear and tear on any engine component.
Why take risk?
