Most heating oil customers don't read their dealer contracts carefully — or at all. They're presented at the beginning of the relationship, often during a first call when you're focused on getting oil, and the terms don't seem relevant until something goes wrong. But the clauses governing pricing, delivery, cancellation, and service define your rights as a customer. Here's a guide to the terms that matter most.
The most important term in any heating oil contract is how price is determined and when it can change.
"Current posted rate" or "dealer's prevailing price": This means you'll be charged whatever the dealer is posting on the day of delivery — no guaranteed price. This is the default for auto-delivery customers who haven't signed a pre-buy or price cap contract. It exposes you to full market price volatility.
Pre-buy contracts: You pay upfront (or agree to pay at delivery against a pre-established price) for a fixed number of gallons at a fixed price per gallon, usually set before the heating season. Read the "maximum gallons" clause — most pre-buys have a cap, and if you use more, additional gallons are charged at the current rate.
Price cap contracts: You pay a premium (typically $0.10–$0.30/gallon) to lock in a maximum price, while retaining the right to benefit if market prices fall below the cap. The premium is the cost of optionality. Read whether the cap applies to all deliveries or only to a specified quantity.
Budget plans: You pay a fixed monthly amount throughout the year, and the dealer reconciles against actual usage at year-end. The monthly payment is typically based on estimated annual usage at a projected price. Read what happens when actual usage or actual prices exceed the budget projection — the true-up can be significant.
Minimum delivery requirements: Many dealers have minimum delivery quantities — commonly 100–150 gallons. If your tank needs only 80 gallons, you may be charged a small delivery fee for orders below the minimum, or the driver may decline to deliver. Understand the minimum before you call.
Delivery access requirements: Contracts typically include a clause stating that if the driver cannot complete delivery due to inaccessible equipment (blocked fill pipe, locked gate, unpaved road conditions), the customer is responsible for the truck charge. If you have seasonal access issues, document them with the dealer in advance.
Estimated delivery timing (auto-delivery): Auto-delivery clauses typically specify that delivery timing is estimated based on degree day tracking and is not guaranteed. The dealer is not liable for a runout if the algorithm misjudged consumption. This is protection for the dealer, not for you — if you know you use more oil than the model predicts (woodstove, larger-than-average house, unusual patterns), you may need to supplement auto-delivery with manual ordering.
Many dealer invoices include a "fuel surcharge" or "environmental fee" of $0.03–$0.15/gallon that isn't reflected in the advertised per-gallon price. This practice varies by dealer — some roll everything into the per-gallon price and quote all-in, others add surcharges at billing.
When comparing dealer quotes, confirm whether the quoted price is the all-in price or whether there are additional surcharges. A dealer quoting $3.45/gallon with a $0.10 surcharge is effectively $3.55/gallon — higher than a competitor quoting $3.52 all-in.
Some dealers bundle service contracts into the fuel delivery agreement — you commit to buying oil from them and receive a service contract at a reduced price or as part of a package. Read the specifics carefully:
Oil dealer contracts are typically annual agreements with renewal provisions. Key terms to understand:
Pre-buy contracts: If you cancel a pre-buy before using all purchased gallons, most contracts allow a partial refund at current market price (not the pre-buy price). If the market has risen above your pre-buy price — common in winter — you receive a refund below what you paid per gallon. Read the refund formula carefully.
Service contract cancellation: Service contracts often have prorated cancellation terms — you receive a refund for the unused portion of the contract year minus a cancellation fee. Mid-season cancellations typically have less favorable terms than end-of-season cancellations.
Switching dealers: There's no contract preventing you from buying oil from a different dealer unless you've signed an exclusive supply agreement (rare for residential customers). You can call a competing dealer for a single delivery while being an auto-delivery customer with another dealer — though auto-delivery dealers won't appreciate discovering this. If you want to switch, the cleanest approach is to notify your current dealer at the end of the season and start fresh with the new dealer.
Pricing is only part of the dealer selection decision. OilOutpost connects you with competing dealers so you can compare both price and terms.
