In July 2016, a mechanic was seen pouring motor oil through a funnel at a Chevron Corp. gas station in Albuquerque, N.M. Fast forward to today, and the cost of group III base oil, vital for motor oil blends, has surged by 175% with the ongoing conflict in Iran, according to industry reports.
As conflicts have unfolded, prices for crude oil and derivatives such as gasoline, diesel, and jet fuel have increased significantly, frequently making the news. Yet, the rising cost of motor oil, an essential lubricant for vehicle engines, has not received the same attention. Your next oil change might cost substantially more. Even if a diplomatic breakthrough happened soon, the issue is far from resolved.
“The price of base oil for synthetic motor oil has over tripled, reaching unprecedented levels,” noted Amanda Hay, an analyst with Independent Commodity Intelligence Services, in an email to NPR.
The U.S., though a net exporter of gasoline and jet fuel, predominantly imports base oil. Base oil is a key component in synthetic motor oil, produced minimally domestically. Once considered a luxury for high-end cars, synthetic oil is now a standard for many everyday vehicles. It’s derived from crude oil or natural gas through advanced engineering, providing a more efficient, lasting lubricant. However, most U.S. refineries lack the capability to produce it.
According to Hay, the U.S. faces the largest trade imbalance globally for **group III base oil**, used in synthetic oils. “Our dependence on the Middle East is significant,” states Holly Alfano from the Independent Lubricant Manufacturers Association. Over 45% of U.S. group III base oil imports come from this region, a trade currently hampered by reduced traffic in the Strait of Hormuz. The Pearl GTL plant in Qatar, pivotal for group III oil, suffered a significant setback when hit by an Iranian missile, affecting production for at least a year.
Alternative sources like South Korea offer some hope, but they too rely on Middle Eastern crude. In the U.S., refineries can produce group II base oils, less advanced but usable for traditional motor oils. However, the choice often falls between producing these oils or more profitable diesel fuel, resulting in scarcity for group II oils as well.
Reopening the Strait of Hormuz might ease supply chains from South Korea, but with ongoing disruptions at Pearl and economic focus on diesel, challenges will persist into the next year. Upcoming U.S. plants addressing these issues are only operational around 2027.
Hay forecasts fewer and costlier options, but a complete shortage seems unlikely. Supply gaps are more probable, with branded motor oils facing the tightest squeeze. Although industry stockpiles have temporarily cushioned the blow, inventories are depleting, causing a market-wide increase in prices.
“Regular motor oil has seen a 60% jump in prices,” reports Nathan Matheson, owner of a repair service in Poolesville, Md., who until now has absorbed the rising expenses rather than transferring them to customers.
The situation compounds with tariff-driven hikes in auto part prices. Despite the Supreme Court’s removal of various tariffs, those on auto parts persist, intensifying financial pressure on mechanics and customers. Consumers are now driving less, opting for eco-friendly transport, or postponing auto services where possible.
Consumers benefit from knowing their vehicle’s recommended motor oil type. Alternatives might exist, but it’s crucial not to substitute without assurance of compatibility. Modern synthetic oils allow for extended mileage beyond the traditional 3,000-5,000 miles interval; referencing your manual is advisable.
For repairs, multiple opinions are beneficial. Matheson advises ensuring essential maintenance isn’t extended until it becomes more expensive. Neglecting minor maintenance can lead to significantly higher repair expenses, such as neglecting a $160 fluid change escalating to a $2,000 repair.
If maintenance is essential, prioritize it to avoid greater costs later on.
