"Global Oil Supply Chain in Crisis: U.S.-Iran Conflict Takes Toll on Synthetic Motor Oil Production A brewing crisis is unfolding in the global oil industry as the ongoing U.S.-Iran conflict disrupts critical imports of Group III base oil, a vital component in the production of synthetic motor oil. The shortage has already started to impact major automakers, with Nissan and Toyota forced to ration supplies to their dealerships in an effort to conserve what little they have. Meanwhile, other manufacturers are taking a more drastic approach, stockpiling inventory in anticipation of a prolonged shortage. As the situation continues to escalate, consumers may soon feel the pinch of higher prices and reduced availability of synthetic motor oil, a key component in many high-performance vehicles."
