Kirkland motor oil
I see that Costco has their own brand of synthetic motor oil. Like other Kirkland branded items, is it any good? Having a sale on 2 pack of 5qt containers for $25 delivered.

Ignorance is bliss (so they say at least) until you have a lubrication related failure. Then you'll change your tune.... as your wallet gets emptied.
You're right, there aren't any.
Actually there are. In the early/mid eighties, Audi had 1,000's, of premature turbo failures on their I5 (2.1 liter) engines (which they fixed under warranty) due to oil coking up the turbo housing bushings because the turbo would overheat if it wasn't cooled down properly prior to engine shut down. (after spirited driving) It cost Audi $$$$$$. The fix: Change the specs to improve the temperature stability of the oil which led to Audi specifying synthetic oil and changing it more frequently. Also, install after run electric water pumps, water/oil cooled turbos, and after run radiator fans. To be fair, Audi warned owners about the cool down issues but hey, . . . . . who reads owners manuals? Some, not all, of the turbo failures led to premature catastrophic engine failures.
Other manufacturers had similar issues with their turbo models until the learning curve took over.
