Just came back from Walmart. Bought four 5-gallon containers of oil. They sure have gone up in price. Over $9 now.
I think you meant to say 5-QUART containers of oil.
Anyway, all petroleum products are going up steadily in price as the price of crude goes ever higher, and $9 for 5 qts of quality motor oil is still cheaper than the same oil at any discount auto parts chain I know of.
