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.

For a long time I have read about many grades of synthetic oils. I would speculate Kirkland is at the low end of the list. Still going to meet specifications and provide long life of your engine.
