Went to two local Wal-Marts here in Middle TN (Franklin and Columbia) looking for a 5qt jug of M1 10w30. There are no more 5qt jugs anywhere! There were the usual single Qt jugs at $4.77 each, but not a single 5qt jug of any M1! Just a couple months ago, either of these WalMarts carried 5w30, 10w30, and 15w50 5qt jugs. Now there all gone, replaced by 5 qt jugs of Castrol. The shelves were full of Castrol Drive Hard, Syntec Blend, and some other standard-issue looking Castrol product for just under $10, all of them 5qt jugs. The heck of it is, none of the synthetic 5qt/single qt's are GC, they're all domestic-made. Hopefully this is just a phase for WalMart and will bring M1 back. P-P-Please bring M1 back. Soon.
