The acdelco oil I've had experience with over the last few years has been blended/bottled under a Phillips 66 contract, and I'd imagine it to be similar to Phillips shield choice. As far as purchasing bay boxes go, the Napa synthetic deal from April was a great opportunity to get a box for cheap. Worked out to $2.92/qt. In general, even though six gallons is a lot for an individual, I really like the bay box and pitcher setup. We use them at my job and I prefer it vastly over a jug or quart bottles. One of the best ideas in motor oil dispensary imo.
