Costco and Walmart raise motor oil prices amid Iran conflict
Costco now sells Kirkland Signature full-synthetic motor oil for $57.99 per 10-quart case and restricts members to two units weekly. These price hikes and rationing measures stem from a global supply shortage caused by the war with Iran. Beseyat reports that Costco prices rose roughly $36 over four months, and Walmart is experiencing similar price increases. Experts believe the shortage will persist, as synthetic oil production remains dependent on refineries affected by the conflict in the Strait of Hormuz.
Why it matters
Synthetic motor oil relies on refinery outputs rather than isolated laboratory production. Disruptions in the Hormuz region directly impact the availability and cost of these lubricants. This creates a ripple effect across major US retailers.
What is confirmed
- Costco increased the price of Kirkland Signature full-synthetic motor oil to $57.99 for a 10-quart case.
- Costco limited members to two units of motor oil per week.
- A war with Iran is causing a global motor oil supply shortage.
Still unconfirmed
- Costco motor oil prices rose roughly $36 in four months.
- Walmart is experiencing motor oil price increases similar to Costco.
