The U.S. auto industry is warning of potential motor oil shortages as the Iran war disrupts global energy supply chains and drives up production costs.
According to CNN, wholesale motor oil prices have surged after damage to Middle Eastern energy facilities and the closure of the Strait of Hormuz disrupted supplies of critical base oils used in lubricants.
Industry executives said shortages of low-viscosity oils such as 0W-20, widely used in newer vehicles, could intensify by summer.

The report said nearly half of the world’s Group III base oil supply comes from Persian Gulf producers. Supplies were further strained after Qatar’s Pearl GTL facility suffered major damage during the conflict.
Independent Lubricant Manufacturers Association CEO Holly Alfano warned that the shortage could last up to a year. Industry groups are now working with the Trump administration and the Energy Department to limit disruptions.
Experts said consumers should expect higher oil change costs and possible delays in vehicle maintenance.
