Crude Oil would seem to work fairly well as money...

It would if it were easy for people to store and spend.

How much crude oil would I need to give Walmart for my cart of groceries? Would they accept it? Would YOU accept it?

Test number 1 is where crude oil fails as a form of money. While, yes, it has value to some people, it can be used as a store of value and a means of accounting, it fails the general acceptability test.
