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.

Just use 0w-20. Your car will never know, other than a little less wear.
it basically is $3.20 per quart before tax.
costco motor oil and mobil 1 oil is pretty close in my opinion... you can do your own research.
unless you're driving a super fancy car that requires specific brand. For a regular citizen, these costco motor oil will satisfy 99% of the drivers out there.
sure the days of the getting a rebate from mobil1 seems to rare now... I recalling basically buying $12 for 5-qtr jug of mobil1 motor oil after rebate... those days seems to be gone with inflation...
now $16 a jug... still not that bad.
~in case some are wondering how long these motor oil will last, if keep unopen. They will last 7 to 8 years when kept unopen indoor with a normal temperature condition.

ProjectFarm did a video [youtube.com]on Kirkland oil. Enthusiasts also did one [youtube.com].
TLDR is yes it's perfectly fine. The vast vast vast majority of people will be perfectly fine with Kirkland oil. Unless you have a supercar.
You can find those specs on Mobil 1, Pennzoil Ultra, Castrol EDGE, etc. not usually on Supertech or others like Kirkland which are bargain basement synthetics.
Closest you'll get is a Kirkland diesel 15W-40 CK-4 fluid but that really isn't meant for your Porsche.
