![Second Automaker Sounds Alarm Over Dwindling Motor Oil Stock [UPDATE]](https://www.mogazmasr.com/uploads/2026/05/19/motor-oil-shortage-4800b560_800w.webp)
Nissan has confirmed an internal bulletin warning U.S. dealers that engine oil supplies may be tightened, after a similar notice surfaced a day earlier involving Toyota service departments and a reported order to ration motor oil stocks. The bulletin says adjustments will begin May 1, 2026, and that allocations of Nissan Genuine Oil, including Mobil and Mobil 1 variants, will be limited to 55% of prior-year purchase levels.
A Nissan spokesperson said the bulletin was authentic but had not been distributed to the company’s dealer network. The document says the automaker is writing to provide an update on the availability of engine oil products across the Nissan network in the U.S., and warns that global supply constraints are affecting key raw materials and refining inputs because of the Middle East conflict. It also says reduced production capacity has been advised for most lubricant products.
The bulletin goes further than a simple supply warning. It says bulk and packaged Genuine Nissan oil supply would be limited to 55% of prior-year volumes on a year-over-year basis, mentions a supplier-driven price adjustment of an unknown amount, and tells dealers they are not required to pay Nissan’s supplier-side rate for bulk oil. Dealers can source bulk oil from wherever they like, the document says, so long as any authorized service uses a Nissan-approved lubricant. That does not have to be a Nissan-sourced product.
The timing matters because the warning landed the same week a separate report said Toyota service departments had been told to conserve oil stocks, suggesting the issue is broader than one company’s internal inventory. Nissan said it is closely monitoring current oil supply constraints in coordination with supplier partners. The overlap points to a problem that may reach across the auto service business, even if the public notices remain fragmented and unevenly distributed.
The shortage is not necessarily about crude oil itself. ExxonMobil says base stocks are the key building blocks of lubricants and greases, that a base stock is a single lubricant component produced by a single manufacturer, and that oil marketers or formulators mix base stocks to make finished products. In practical terms, that means pressure can emerge deep in the supply chain before drivers ever see a warning light. Many modern engines also require synthetic or partially synthetic motor oil, which makes those inputs even more central to routine service.
For now, the clearest sign of strain is not at the pump but in dealer back rooms, where companies are trying to stretch inventory before the May 1 change takes effect. If the warnings prove accurate, the immediate burden will fall on service departments first, with possible price shifts and tighter allocations arriving before most motorists notice anything has changed.
