US retailer rationing motor oil as prices quadruple
The move follows a fourfold rise in wholesale motor oil costs and reports of global shortages tied to the conflict around Iran.

A US retailer began rationing motor oil on September 20, 2026, after wholesale prices rose fourfold as supplies of a key engine lubricant ran short, officials said. Traders said industrial lubricant markets tightened and availability narrowed; reaction pending.
Iran conflict disrupts base oil exports
Officials said the shortages reflect disruptions to shipments of base oils and additives linked to the conflict around Iran, constraining components used in vehicle engine lubricants. Retailers and wholesalers reported empty shelves and limits on customer purchases, the officials said.
Traders added that inventories held by distributors have been drawn down as buyers compete for scarce cargoes, pushing contract prices higher. Service centers and fleet operators cited rising procurement costs and selective purchasing by suppliers, traders said.
If shipments are restored within weeks, officials and traders said inventories could begin to recover and price pressure would ease. If flows are not restored by October 31, 2026, analysts warned, further rationing and sustained upward pressure on retail prices are likely, forcing broader pass-through to motorists and commercial fleets.
