What $6.04 heating oil, up 70% in a year, actually means for a diner, a daycare and an auto shop

The Energy Information Administration's first heating-season survey puts the average U.S. residential price of No. 2 heating oil at $6.042 a gallon for the week of October 5. A year earlier, on October 6, 2025, the same survey showed $3.555. That is $2.487 more per gallon, or 70%. It is also above the $5.566 recorded on March 23, the high of last winter in EIA's weekly history, which was already set after the war with Iran began.

On September 28 we estimated that wholesale prices pointed to roughly $6.21 delivered. The measured number came in about 17 cents lower. That is a smaller miss than it sounds, and the reason is the useful part.

The thing the "price has doubled" headline gets wrong

Wholesale No. 2 heating oil in the same EIA survey is $5.025 a gallon, up from $2.371 a year ago: $2.654, or 112%. The price a building owner pays is up $2.487, or 70%. The difference is that part of the delivered price does not move with oil: the truck, the driver, the dealer's margin and local taxes.

Per gallon	Oct. 6, 2025	Oct. 5, 2026	Change
Wholesale heating oil	$2.371	$5.025	+$2.654 (+112%)
Delivered (residential survey)	$3.555	$6.042	+$2.487 (+70%)
Gap between the two	$1.184	$1.017	-$0.167
Residential propane	$2.417	$2.598	+$0.181 (+7.5%)

So a dealer's quote is a smaller multiple of last year than the wholesale chart suggests, but it is still $2.49 a gallon, and a building burns thousands of gallons. Oil itself rebounded about 2% on Monday on attacks around Saudi Arabia and tankers near the Strait of Hormuz, with Brent near $107 and West Texas Intermediate near $94, OilPrice.com reported. Its quote board showed heating oil futures slightly lower on the day, which is a reminder that crude and the fuel in your tank do not always move together.

Three buildings, three bills

The gallons below are illustrative; use your own delivery tickets. Each applies the year-over-year increase of $2.487 to a six-month season.

The diner: about $4,974 more, or $829 a month

A restaurant building that burns 2,000 gallons a season pays 2,000 times $2.487, or $4,974 more than last winter's pricing. Over six months that is $829 a month. A diner serving 1,500 covers a month would need roughly 55 cents more per cover ($829 divided by 1,500) to absorb it without touching its own margin. CheckThisBiz has 605,380 independent restaurants on file, and our restaurant playbook covers menu pricing.

The daycare: about $8,705 more, and no way to turn it down

A child care center on an oil boiler burning 3,500 gallons faces 3,500 times $2.487, or $8,704.50 more, which is $1,451 a month. A center cannot run the building colder in January the way a shop can. Spread over 40 enrolled children it is about $218 per child for the season, or roughly $36 a month. Tuition is usually set once a year, so the timing matters more than the size: the cost arrives before the next fee schedule does. There are 58,848 independent child care businesses on our file.

The auto shop: about $3,731 more, or 52 cents per billed hour

A repair shop with an oil-fired unit heater using 1,500 gallons pays 1,500 times $2.487, or $3,730.50 more, which is $622 a month. A shop billing 1,200 labor hours a month would need about 52 cents more per hour. That is small against a labor rate, which is the point: for a shop this is a line-item adjustment, not a crisis. We list 224,738 independent auto repair shops, and the auto repair playbook has the rate-setting steps.

And if you heat with propane

Delivered propane is up 18 cents a gallon, 7.5%, though wholesale propane is up 20 cents, or 23%, from $0.854 to $1.054. A greenhouse or nursery using 10,000 gallons is looking at about $1,810 more, or $302 a month. That is roughly a third of what 2,000 gallons of oil adds for the diner. If you are one of the 44,163 landscaping and nursery businesses on our file and you heat with propane, this is a budgeting item, not a pricing event.

What to actually do

• Pull last year's delivery tickets and multiply gallons by $2.49. That is your increase if prices hold where they are. Divide by six for the monthly figure.
• Ask your dealer what a fixed price and a capped price cost today, and compare both against $6.04. A fixed price removes the risk of another spike and also removes the benefit if a ceasefire brings oil down. A cap costs a premium and keeps the downside. Neither is right for everyone; the right one is the one your cash flow can survive being wrong about.
• If you are a landlord on gross leases, check each lease for an operating-cost or fuel escalation clause and its renewal date before the first delivery, not after.
• Do not prepay a full season on a hunch. Delivered prices have moved with the war all year, and nobody can tell you the direction from here. Watch EIA's next release on October 15 for the second weekly reading.
