US motor oil shortage: prices up 300%, Costco rations, Walmart low stock

Motor oil prices in the US have surged over 300% since the start of a war, with Costco limiting purchases to two units per week and Walmart reporting low stock. The shortage signals supply-chain disruption in refined petroleum products, likely driven by conflict-related feedstock or logistics constraints. The extent and duration of the shortage remain uncertain, but it may pressure consumers and downstream industries.
