Costco Motor Oil Prices Skyrocket Amid Global Shortage

Costco has nearly doubled the price of its Kirkland Signature full-synthetic motor oil to $57.99 per unit, citing a global lubricant shortage tied to the ongoing Middle East conflict.

The company is also limiting purchases to two units per customer per week, while Mobil 1 carries a five-per-member limit with six quarts priced at $44.

The shortage is attributed to a refinery explanation that most shoppers never see: when margins on finished fuel are strong, refiners favor fuel over lubricant stock, according to The Auto Wire.
