When I was much younger, many filling stations, especially locally-owned stations, sold reclaimed oil in bulk for automobile use. My father used to keep a couple of five-gallon cans of the stuff to pour into his Packards. Selling reclaimed oil pretty much disappeared with the homogenization of retail gas stations in the 1960s (which also ended distribution by local wholesalers who received petroleum products in freight cars--mandatory FC content). Of course, old oil is still recycled, but is rarely sold at retail, and most gas stations are now convenience stores that make more money selling snack food.
