Here in Texas, every WalMart I've been into is out of everything .... nothing left not even MC 5000. For a while I would see the 4qt jugs of T&DD, now those are gone as well.
As stated by others, many other stores have plenty, because they do not move much product. It will be interesting when those stores sell their dusty shelves out as well.
If I follow my OLM, I'm course for 7k oci ... so with my stash of 12 total qts... I have enough for two oil changes .... probably will last about a year.
