Just found QS full synthetic on clearance for $1.75 at a local Walmart! Checked 2 other local stores and they only had the blend in stock. Walmart only had Quaker State conventional on the shelves, the syn was on a clearance rack ... leads me to believe that they're clearing out their Quaker State Synthetic and most likely not carrying Quaker State Synthetic anymore. Oh well, I've been looking for a new synthetic oil for some time now since M1 jacked up their prices... 12 quarts of QS will see me through a couple more oil changes.
