What drives heating oil prices

Why the price moves

Heating oil is a refined petroleum product, so its price generally follows the wholesale fuel market, which tracks crude oil and refined-fuel supply and demand. Cold weather, refinery issues and world events can all push prices up or down.

Because that market moves every day, our posted price can change daily. That is why the live prices on this page are the only number worth trusting. Our post on why home heating oil prices change daily goes deeper.

Demand matters too. When a cold snap hits, more people order at once and the market tends to feel it. For a fuller look, see what really drives heating oil prices on Long Island.

Why bigger orders cost less per gallon

More gallons, lower price per gallon

Larger orders get a lower per-gallon price. Online you can order 50, 100, 150, 200, 250, 300 or 500 gallons, and the price per gallon generally drops as the order grows.

As a dated snapshot, on October 26, 2026 our posted price was about $5.39 to $6.15 a gallon depending on order size. That is not today's price, so check the live grid on this page before you order.

One bigger delivery is usually cheaper to make, per gallon, than several small ones, which is the common reason suppliers price this way. If your tank has the room, a larger order is worth a look. If cash is tight, a smaller order still comes with free delivery.
