Costco Rations Motor Oil After Global Shortage Sends Prices Soaring
Global Shortage Has Led to Motor Oil Rationing at Costco

A global lubricant shortage has pushed Costco to ration motor oil, with Kirkland Signature full-synthetic now priced at $57.99 for a 10-quart case, up from the mid-$30s. Members are limited to two units every seven days, and Mobil 1 purchases are also capped. The squeeze stems from tighter base-oil supply and the costly, complex process of formulating oils that meet modern engine and API standards.
Seeing motor oil rationed at Costco is unusual, and combined with the sharp price increase, it shows just how much pressure the lubricant market is currently facing.
