Why heating oil prices change

Two neighbors fill their tanks a month apart and pay noticeably different prices, and both are convinced somebody got taken. Usually nobody did. The price on a heating oil ticket is built in layers — a global market at the bottom, an Ohio winter in the middle, and a truck route on top. Here are the layers, in the order they stack.

Layer 1: crude oil, the base of everything

Heating oil is refined from crude oil, and crude trades on world markets around the clock. Wars, OPEC decisions, a refinery fire on another continent, a weak or strong dollar — all of it moves the base cost of every gallon before any Ohio company touches it. This is the layer no local company controls, and it's the biggest reason prices drift up or down over a season. When crude swings sharply, delivered prices follow within days to weeks, because the company is refilling its own storage at the new price constantly.

Layer 2: the heating season itself

Heating oil demand is brutally seasonal. Almost everybody needs it in the same sixteen weeks, and the whole Northeast and Midwest bid for supply at once. Cold snaps tighten it further: a forecast that drops ten degrees can move wholesale prices before the cold even arrives, because every distributor in the region is topping off storage at the same time. The same gallon is simply worth more in the third week of January than in the second week of September — which is the practical thinking behind filling your tank in the fall and behind pre-buy and cap plans.

Layer 3: getting it to Ohio, and to your street

Between the refinery and your basement tank sit pipelines, terminals, and a loading rack where the delivery company fills its trucks. Each step adds cost, and each can add friction: a terminal allocation during a cold snap, a long haul from the rack, winter road conditions. Your local company's own layer — trucks, insurance, drivers, the office — is real too, and it's why the same day's price differs between a lean rural operation and a full-service company with 24-hour burner service. You're not only buying oil; you're buying the machine that brings it. (That machine's math is also why minimum deliveries exist.)

What this means for you, practically

• Timing beats shopping. The difference between companies on the same day is usually smaller than the difference between September and January for the same company.
• Don't judge a company by one ticket. A fair test is its price against the market over a whole season — which is exactly what budget and cap plans are designed to smooth out.
• Small fills cost more per gallon in any market, because the delivery cost is spread over fewer gallons. Fewer, fuller deliveries are the cheapest habit a homeowner can build.
• Nobody honest can promise you next month's price. If a salesperson guarantees where the market is going, that's a reason to walk away, not sign up.
