While in WM yesterday I noticed they have the 5 qt. jugs of SN/GL5 rated QSUD still selling for $19. I was tempted to pick up a couple of jugs because they (supposedly) meet the dexos requirement of my new Cruze. Two things kept me from making the purchase, 1) yesterdays Cst thread which impunes the cold starting abilities of QSUD, and 2) all the jugs seem to be underfilled compared to QSGB, QSHM, PP, PU, PYB (all the SOPUS products which use the exact same jug).
I know the jug probably has 5 quarts in it, but if so the others must have 5+. They seem to have a 1/2 inch more product in them.
