Costco hikes Kirkland motor oil price to $58, limits purchases amid rising crude oil costs.

Costco has raised the price of its Kirkland Signature full synthetic motor oil to $58 per 10-quart case, up from $30-$35 in previous years, and is now limiting customers to two cases per week. The price increase is driven by rising crude oil prices, which have surged due to supply disruptions in the Middle East, pushing Brent Crude above $109 per barrel. This has also caused gasoline and diesel prices in the U.S. to rise significantly, with diesel surpassing $6 per gallon. It remains uncertain if other retailers will follow Costco's lead with price hikes or purchase limits.
