As a 1 quart bottle it is cheap indeed. But Wallmart or Amazon sells quite many high quality options for the same price/quart if you are buying a 5 quart bottle, and most cars on the market take at least that much oil anyways. I recently bought 5x5 quart jugs of Valvoline Restore and Protect for less than $6 a quart, and that is about the most expensive oil majority of our cars can realisticly benefit from.
PS: Kirkland is $44/12 quarts right now, that puts it below $4 per quart. I think it is a quite decent oil
