You are right that the stock varies by store at Walmart, but it is not up to anyone who works in the store. Those decisions are made at a higher level as to which store carries what items.
It depends on many factors, such as size of store (shelf-space), demographics of customers, past experience selling a particular item, regional preferences, etc.
All the Super Centers near me carry M1 0W-20 in both jugs and quart containers.
