Heating oil prices feel unpredictable, but they're actually driven by a set of identifiable factors — some global, some regional, and one entirely local. Understanding these factors won't let you predict prices, but it will help you recognize the conditions that make prices spike and know which variables you can actually influence.
Crude oil is the raw material that gets refined into heating oil. Roughly half to two-thirds of the retail price of heating oil tracks crude oil prices. When OPEC+ cuts production, a pipeline gets disrupted, or geopolitical tension spikes, crude prices rise — and heating oil follows within days.
WTI (West Texas Intermediate) and Brent crude are the two benchmarks that drive US fuel pricing. The EIA (Energy Information Administration) publishes weekly crude price data, and their weekly petroleum status report is the most reliable tracking tool available to consumers.
The consumer implication: you cannot control global crude prices. What you can control is timing (buying when crude is lower in the seasonal cycle) and dealer competition (capturing the full benefit of low crude prices by not overpaying dealer margin).
Refineries convert crude into usable products: gasoline, diesel, jet fuel, and heating oil. The "crack spread" is the refinery's margin — the difference between the cost of crude and the price of the finished product.
Refinery disruptions — unplanned maintenance shutdowns, hurricanes affecting Gulf Coast refineries, capacity constraints — can spike crack spreads and therefore heating oil prices independent of crude. The Northeast gets much of its refined product from Gulf Coast refineries and Atlantic Basin imports, making regional supply vulnerable to disruptions that don't affect crude prices directly.
The Colonial Pipeline (which delivers refined products from the Gulf to the Southeast and Mid-Atlantic) is a key Northeast supply artery — disruptions have historically caused rapid Northeast price spikes.
The Northeast is the most heating-oil-dependent region in the US, and it has limited regional refining capacity. The EIA tracks Northeast distillate fuel oil stocks weekly — when stocks are low relative to the 5-year average ahead of a cold winter, prices are more vulnerable to spikes during demand surges.
The New England and Mid-Atlantic states are supplied primarily through terminals in New York Harbor and Providence, RI. Marine imports from Europe and Canada supplement domestic supply. When global shipping disruptions, low European production, or weather-related delays restrict imports, the region can experience supply-driven price spikes that exceed what crude oil alone would explain.
Heating demand is the primary driver of winter price volatility. The heating degree day (HDD) is the standard measure — it tracks how far the average temperature falls below 65°F on a given day. More HDDs = more fuel burned = more demand pressure on prices.
Forecast weather affects prices even before demand materializes. If the NOAA 30-day outlook predicts colder-than-normal temperatures for New England, heating oil prices in the futures market often rise in anticipation. This means that even a long-range weather forecast can move your dealer's next-day price.
The most extreme price events typically happen when: cold weather arrives earlier than expected, temperatures are significantly below normal for an extended period, and regional stocks are already below average — all three converging.
Global crude prices are set by markets. Refinery margins are set by industrial economics. Regional supply reflects supply chain logistics. None of these are within a Connecticut homeowner's control.
Local dealer margin is different. In any given town on any given day, multiple dealers are supplying the same product to the same customers. Their upstream costs (rack price from the terminal) are similar. Their margins differ based on operational efficiency, volume, debt service, and competitive pressure.
When dealers know they're competing for your business, margins compress. When a homeowner calls one dealer and never checks alternatives, that dealer has no incentive to sharpen their pencil. The spread between the best and worst dealer price in a given market on a given day is consistently larger than most homeowners realize — often $0.30–$0.50 per gallon or more.
This is the only factor that active, competitive shopping directly addresses. Everything else is background noise you're along for the ride on.
You can't move crude oil markets. You can make dealers compete for your business. OilOutpost does exactly that — one request, multiple competing bids.
