Costco limits motor oil sales and raises prices amid rising oil costs and Middle East tensions

Costco has restricted member purchases of motor oil to two units per week and increased prices significantly, with its Kirkland Signature synthetic motor oil now priced at $57.99 for a two-pack, up from around $30. This move comes as crude oil prices surge due to ongoing conflict in the Middle East, including Saudi Arabia's closure of a key oil pipeline after drone attacks. The supply of motor oil is further constrained because refiners prioritize fuel production over base oils used in synthetic motor oil. These supply pressures have also pushed U.S. gasoline and diesel prices to record highs, impacting consumers and the broader market.
