Will there be a shortage of motor oil? What the official record shows for your car

Will there be a shortage of motor oil? What people are asking

"Will there be a shortage of motor oil" is a question people type into search engines, like the same question about diesel and toilet paper. This page checks it against the official places a supply problem would show up: federal notices, EIA's petroleum supply data and BLS's price data, and against the official advice for your car.

We don't predict whether a shortage will happen. We report what those sources say today and what it means for a household.

What the official record shows

Notices: a search of Federal Register documents published since January 1, 2025 found none about a shortage of motor oil, base oil or lubricating oil. The three documents that mention motor oil at all are two EPA fuel actions and a Federal Trade Commission merger order. That search doesn't cover every state, store or brand, so it can't rule out a gap on a local shelf.

Supply: EIA counts motor oil in its "lubricants" category, which also covers industrial oils and greases, so its figures are wider than car oil. In its Petroleum Supply Monthly of October 30, with data to August 2026, US lubricant stocks were 9,648 thousand barrels in August, down from 11,053 thousand a year earlier, about 13% lower by our reading.

US refineries and blenders made 4,997 thousand barrels of lubricants in August, about 10% less than a year earlier. Over January to August, production was about the same as in 2025, by our reading, while product supplied, EIA's measure of how much reaches users, was about 23% higher.

What prices show

Shop prices: BLS's Consumer Price Index has an index for motor oil, coolant and fluids, which BLS notes is based on a substantially smaller sample. In the release of November 10, it rose 0.3% from September to October 2026, after 1.0% in September and 2.6% in August. By our reading of the index, it rose about 5% from June to July, and October's level was about 9% above September 2025. Earlier in the year it ran a little below 2025's level: June's was about 1% lower than June 2025's.

BLS couldn't publish the usual 12-month change, because it collected no data for October 2025 during the 2025 lapse in appropriations.

Wholesale prices, which are not shop prices: BLS's producer price index for lubricating oil base stocks, the oil that motor oil is blended from, jumped in April and in October was more than double its level a year earlier, by our reading of its preliminary figures. Its index for finished lubricants was about 25% higher than a year earlier. BLS's figures don't give a reason for the rise.

What is confirmed, and what is not

Confirmed: lubricant stocks are lower than a year ago, according to EIA, and BLS's figures show wholesale lubricant prices rising since April and shop prices for motor oil, coolant and fluids rising since July.

Not confirmed: a motor oil shortage. We found no federal notice of one, and no official source we read forecasts one. Lower stocks and higher prices are not the same as empty shelves. If an official body does report a supply problem, we will update this page.

How much motor oil should a household keep?

No official list tells households to keep a supply of motor oil. Ready.gov's car page says: "Have a mechanic check the following on your car before an emergency," and its list includes "Oil", "Antifreeze levels" and "Fuel and air filters". It also says: "Keep your gas tank full in case of evacuation or power outages." The Red Cross says to keep your car gas tank at least half full.

Our reading, not an official figure: keep up with your car's normal oil changes, and if you like to top up between changes, one container of the grade in your owner's manual is enough. Our winter car kit guide covers what's worth keeping in the car.

What to do with used oil

If you change your own oil, EPA says to "place it in a leak-proof can or container" and to check with local automobile maintenance facilities, waste collectors and government waste officials about where to drop it off for recycling. It also says to drain and recycle used oil filters.

EPA says "used oil from one oil change can contaminate one million gallons of fresh water." It also says motor oil "does not wear out" and that recycling it "saves a valuable resource."

What not to do

Don't bulk-buy motor oil because of a search trend or a headline. In 2020, FEMA said that buying weeks or months of supplies in advance "leads to shortages and makes it difficult for other families to take care of themselves." Ready.gov's pandemic page says: "Buy supplies slowly to ensure that everyone has the opportunity to buy what they need."

Don't pour used oil down a drain or onto the ground. EPA calls used motor oil "insoluble, persistent" and says it can contain toxic chemicals and heavy metals.
