The ‘imminent’ oil crisis isn’t at the pump—it’s under your hood
The ongoing war in Iran has led to a significant supply chain crisis affecting engine oil changes in the U.S. Despite high domestic oil production, the country relies heavily on Middle Eastern base oils for modern motor oils. Prices are expected to rise sharply, with shortages anticipated as early as June.
- ▪Prices for motor oil have increased by approximately 35% and are expected to rise further.
- ▪The closure of the Strait of Hormuz has severely impacted the supply of Group III base oils, crucial for motor oils.
- ▪The American Petroleum Institute has introduced emergency provisional licensing to allow manufacturers to use alternative base oils.
