# Toyota warns dealers of motor oil shortage amid Iran conflict

Toyota issues warning: Dealers are told to substitute certain oil grades for one service interval as supplies of 0W-8 and 0W-16 tighten due to petrochemical shortages. Global supply squeeze: Iran war disruptions and Qatari facility damage have cut off 44% of U.S. Group III base oil supply, hitting synthetic oil production hard. Impact on drivers: Motorists may face higher prices, limited oil choices, and delayed maintenance, though short-term substitutions are expected to avoid engine damage.
