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 personally do it online for that reason.
But it's OK because you get stuff you want.
Instead Costco shoppers pick up other things beside this which would make this deal worth considering.
