The cost of a routine oil change could rise sharply as the Iran war disrupts key supplies used to produce synthetic motor oil, according to industry reports.
Automakers, dealerships and distributors are reportedly scrambling to secure synthetic motor oil as tensions in the Middle East create pressure on critical supplies from the Gulf region.
The concern centers on Group III base oils, a highly refined petroleum product used to make many modern synthetic motor oils and transmission fluids.
Some suppliers have warned that shortages could hit parts of the U.S. market by June if supply disruptions continue.

The price pressure is already being felt by some repair shops.
Chris Harp, owner of A&C Auto Repair in Alabama, told WBRC that a 55-gallon drum of full synthetic oil that previously cost between $300 and $400 has recently climbed to around $1,000.
That kind of increase could push a standard synthetic oil change from about $65 to as much as $85 or $90 at some shops.
Automakers are also beginning to respond.
Nissan has reportedly started rationing two popular synthetic motor oils to dealerships, with some allocations reduced to a little more than half of last year’s levels.
Toyota has also warned dealers that certain oil supplies could become tight because of production and logistics constraints in the global petrochemical supply chain.
The shortage has raised concerns beyond routine maintenance.
Some industry executives say automakers could face problems if shortages spread to transmission fluids and factory-fill oils needed to move newly built vehicles off assembly lines.
Arnold Gacita, CEO of Texas-based Petra Automotive Products, compared the situation to the semiconductor shortage during the COVID era, when automakers could build vehicles but struggled to finish or deliver them because a critical component was missing.
The Independent Lubricant Manufacturers Association has reportedly warned that the shortage could last into mid-2027 if supply problems continue.
But not everyone believes drivers should panic.
Automotive analyst Lauren Fix said the shortage risk may be exaggerated by panic buying and alarmist headlines.
She said the biggest concern appears to involve premium Group III base oils used in thinner synthetic blends required by some newer vehicles, not every type of motor oil.
Fix said standard motor oils remain widely available and that many drivers using common blends such as 5W-30 or 10W-30 may mainly see higher prices or fewer discounts rather than empty shelves.
She also warned that consumers rushing to stockpile oil could make the shortage worse.
For now, the most likely impact is higher prices at some repair shops and tighter supplies for certain synthetic oil products, especially those required by newer vehicles.
Why It Matters
The issue shows how quickly Middle East instability can affect everyday American costs. Even if the conflict feels far away, disruptions to oil and petrochemical supply chains can reach consumers through routine expenses like vehicle maintenance.
What Comes Next
Drivers may see higher prices for synthetic oil changes if supply pressures continue. Automakers and dealerships are expected to keep searching for substitute supplies while monitoring whether shortages spread to transmission fluids and factory production lines.
A related report warned that synthetic motor oil shortages tied to Middle East supply disruptions could push routine oil change prices higher.
