Costco imposes purchase limits on motor oil, hikes prices by nearly double

Costco set purchase limits and price hikes on motor oil as the company grapples with rising prices from global energy market disruptions.

A case of two 5-quart bottles of Costco’s Kirkland Signature full-synthetic motor oil now costs $57.99, a near 100% increase from its previous approximate price of $30. The bottles are now rationed as well, as each customer can only buy two boxes per week per membership.
