Oh, my! I buy a 5 qrt jug of Quaker State Defy from Walmart. ALL 5 qrts are in the SAME jug, right from walmart. That's right! ONE JUG, containing all 5 quarts of oil. Sold this way from Walmart. AND other places. Pour the 8 oz. little container in the 5 quart jug of oil, and shake it. Again, they sell oil in 5 quart jugs. ALL 5 quarts are in the same jug. Comes this way from the store. Again, ONE container containing FIVE quarts of oil. This is how it is delivered to the store.
