The war with Iran is making oil changes pricier. And a deal won't solve it

The surge in motor oil prices—up 175% since the start of the year—is more than an inconvenience for drivers. It reflects a deeper vulnerability in the global energy system, where geopolitical tensions in the Strait of Hormuz and broader Middle East conflicts are disrupting supply chains in ways that persist even if a ceasefire is reached. Base oils, the refined petroleum components used in lubricants, are derived from crude oil refining, and their production is highly concentrated in regions like the Middle East and Asia. When regional instability disrupts refinery operations or shipping routes, the ripple effects extend far beyond immediate fuel costs, affecting everything from automotive maintenance budgets to industrial machinery reliability. This isn’t the first time the industry has faced such pressures, but the scale and duration of the current spike suggest structural challenges. Unlike gasoline, which has alternative sources and price controls in some markets, base oils are a niche product with limited substitution options. The refining process itself is energy-intensive and subject to strict environmental regulations, which have slowed capacity expansions in key producing countries. Meanwhile, demand for high-quality lubricants has grown with the rise of electric vehicles—ironically creating a paradox where internal combustion engines face higher costs even as they phase out. What happens next depends on whether the conflict escalates further or stabilizes without a comprehensive resolution. A prolonged disruption in Iranian oil exports could push base oil prices even higher, while a temporary de-escalation might ease pressure without fully resolving supply constraints. The industry may also accelerate investments in synthetic or bio-based alternatives, though these won’t replace mineral-based lubricants overnight. For consumers, the immediate takeaway is that oil changes will likely remain pricier for the foreseeable future, regardless of geopolitical headlines. For policymakers, the episode underscores the fragility of global supply chains and the need for diversified production—not just for energy, but for the specialized materials that keep modern economies running. The real question isn’t whether a deal will happen, but whether the world is prepared for the next disruption when it does.
