How to Read Heating Oil Prices (And What Affects Them)

You check prices online and see one dealer at $3.29 and another at $3.89 — for the same fuel, in the same town. What gives?

Heating oil pricing isn't random, but it's not straightforward either. Here's what actually drives the number on your receipt.

The Global Layer: Crude Oil

Heating oil is refined from crude oil, so global crude prices set the baseline. When you hear about OPEC production cuts, Middle East tensions, or changes in U.S. oil output, those events ripple through to your local price within days or weeks.

Crude oil typically accounts for about 40–50% of the retail price of heating oil. The rest is refining, distribution, and the dealer's margin.

The Refining Layer

Crude oil has to be refined into heating oil (which is essentially the same as diesel fuel, technically called No. 2 fuel oil). Refining capacity, seasonal demand shifts, and maintenance shutdowns at refineries all affect the "crack spread" — the difference between crude oil cost and refined product cost.

In the Northeast, most heating oil comes from refineries along the Gulf Coast and East Coast. When those facilities have issues, regional supply tightens and prices jump.

The Distribution Layer

Heating oil moves from refineries to regional terminals via pipeline and barge, then from terminals to dealers by truck. Each step adds cost. Distance from major terminals matters — a dealer in rural Vermont pays more for distribution than one near the New Haven terminal in Connecticut.

The Dealer Layer: Where the Variance Lives

This is where that $0.60 spread between dealers in the same town comes from. Factors include:

• Volume: Larger dealers buy in bulk at lower wholesale prices and can pass savings on.
• Overhead: A family operation with two trucks has very different costs than a company with a fleet of 20 and a sales office.
• Business model: Cash/COD dealers who don't extend credit typically offer the lowest prices. Full-service companies with payment plans and service contracts charge more.
• Competition awareness: Dealers in competitive markets price more aggressively. In areas with fewer options, prices tend to be higher.

What About Volume Pricing?

Most dealers offer tiered pricing based on how many gallons you order. A common structure looks like this: 100 gallons at $3.69, 150 gallons at $3.59, 200+ gallons at $3.49. The more you buy, the lower your per-gallon cost.

If your tank can hold it, ordering a larger quantity usually saves money. But don't order more than your tank can hold or more than you'll use before prices might drop further.

When Prices Say "Call for Price"

Some dealers don't post prices publicly. This is often a signal that their prices are higher than competitors — if they had the lowest price, they'd want you to see it. It can also mean they adjust pricing frequently based on market conditions.

Dealers who post transparent pricing are usually the most competitive. That's exactly what OilOutpost helps you find.

Bottom Line

The price of heating oil is driven by forces largely out of your control — crude markets, refining, and distribution. But the dealer margin — often the biggest variable in what you actually pay — is entirely within your control. Compare prices, order smart volumes, and don't assume your current dealer is giving you the best rate.
