Costco has initiated a restriction on the purchase of its house brand motor oil, limiting customers to two boxes per week. This move comes as drivers nationwide grapple with increasing gas and diesel prices. Costco, known for offering bulk discounts, enacted this limitation after a notable price increase for Kirkland Signature full synthetic motor oil, initially reported by The Auto Wire.
The motor oil product is crucial for vehicle maintenance, used to lubricate and protect engine parts during oil changes. It helps reduce wear, manage heat, and ensure efficient engine performance. Currently, Costco lists the product—a 5-quart, two-bottle case for gasoline vehicles—at $57.99, a significant rise from the mid-$30s price that had been consistent for years.
Costco has set a purchase limit of one transaction per membership, allowing only two units every seven days. The duration of this cap remains uncertain. Restrictions also apply to other motor oil purchases, such as a six-quart case of Mobil 1, now capped at five per member.
As noted by The Auto Wire, the rationale for such caps may stem from uncertainties regarding stock availability or anticipations of future price hikes, influencing Costco’s decision to prevent stock-buying.
Newsweek sought comments from Costco via email and awaits a response. The current situation raises the question, ‘Why Is Costco Capping Purchases—And Will Other Sellers Follow?’ Synthetic motor oil like Costco’s consists predominantly of base oil, derived from crude oil refining. The ongoing conflict in Iran and resulting oil price spikes have driven oil companies to prioritize converting crude oil into more profitable products like petrol and diesel, potentially leading to decreased motor oil production.
This supply squeeze results in higher prices across the supply chain, affecting manufacturers, distributors, and retailers, ultimately impacting consumers—even at budget retailers like Costco. Enhanced quality standards and stringent testing for motor oil production have further increased costs, challenging drivers who prefer self-conducted oil changes to save money.
On Monday, oil prices surged over 3% from the previous day, following a 9% increase last week due to escalating tensions and attacks in the Middle East. Brent crude, a vital global price benchmark, rose beyond $100 a barrel last week and surpassed $108 on Monday amid ongoing conflict.
So far, major Costco competitors have not introduced purchase limits. Walmart offers synthetic oil of equivalent brand at approximately $32 per 5-quart jug, while a two-bottle pack sells for nearly $64. AutoZone provides Mobil 1 Standard Full Synthetic 5W-30 Engine Oil 5 Quart for $40.99 in a two-bottle package. On Amazon, the same product sells for $31.97 per bottle and $63.94 for two.
Newsweek reached out to Walmart, AutoZone, and Amazon for comments but awaits responses. Costco’s Kirkland motor oil serves as an appealing cost-effective alternative to premium brands, potentially motivating the retailer to implement purchase restrictions to curtail stockpiling and resale.
