Most Nassau County homeowners aren't trying to become heating oil experts. They just want to know: what's the price, when can you deliver, and is there anything I'm going to get surprised by later?
That's a reasonable ask. And yet the heating oil industry has a long history of making simple answers hard to find — buried fees, vague quotes, and contracts that look straightforward until they aren't.
This guide is for the Nassau County homeowner who's done comparison shopping and wants a clear, honest picture of what COD oil delivery actually costs. We'll walk through current price ranges, what moves them up or down, and what to watch for when you're evaluating a supplier.
Fuel Oil Prices on Long Island: What the Numbers Actually Look Like
COD heating oil prices on Long Island currently range from roughly $2.89 to $3.49 per gallon, depending on your location within Nassau County, order size, and the supplier you choose. Those numbers move daily — sometimes by several cents — based on wholesale crude oil markets, seasonal demand, and how far your delivery is from the supplier's terminal.
For context, a standard Nassau County home runs a 275-gallon above-ground oil tank. A fill from near-empty at $3.20 per gallon comes out to around $880. That's a meaningful purchase, which is exactly why it's worth understanding what you're actually paying for — and what you're not.
Home Oil Prices Today: Why They Change and What Drives Them
If you checked the price yesterday and it's different today, that's not a glitch. Heating oil is a commodity, and its price at the retail level reflects what's happening in the wholesale market — crude oil futures, refinery output, pipeline availability, and regional supply and demand all play a role.
On Long Island specifically, proximity to wholesale fuel terminals matters too. Suppliers who are closer to their source terminals can pass along lower transportation costs, which is one structural reason why prices vary between companies even on the same day.
Seasonal timing is the other major factor. Historically, Long Island heating oil prices are lowest in the summer and early fall, when demand is at its minimum. Once temperatures drop and furnaces kick on across Nassau and Suffolk Counties, prices climb. During a nor'easter or a sustained cold snap — the kind Long Island sees every few winters — emergency delivery premiums can run as much as 50% above the standard rate.
For COD customers, this dynamic is actually an advantage. Unlike homeowners locked into a full-service contract with a price set months earlier, you can order when the market dips. If October comes in mild and prices soften, you can fill your tank at the lower rate. If you're on a contract, that flexibility doesn't exist.
One more thing worth knowing: NYSERDA — the New York State Energy Research and Development Authority — publishes bi-weekly average residential retail prices for home heating oil, broken down by region. Long Island, meaning Nassau and Suffolk Counties, is tracked as its own reporting region. It's a useful public benchmark if you want to verify whether a quoted price is in line with the market.
Is COD Oil the Same Quality as Contract Oil?
This question comes up more than you'd expect, and the answer is straightforward: yes, it's the same product. COD heating oil and contract heating oil are both standard #2 fuel oil, sourced from the same wholesale terminals. The price difference between a COD supplier and a full-service contract company has nothing to do with the quality of the fuel — it reflects the difference in the service model.
Full-service contract companies bundle in extras: automatic delivery scheduling, service contracts, burner maintenance plans, and administrative overhead. Those things cost money, and that cost gets built into the per-gallon price. COD delivery strips all of that out. You order when you want, pay the current market rate, and that's it.
That said, "COD" doesn't mean cash at the door anymore either. The term originally meant cash on delivery, but in today's market it really just means no annual contract. Most reputable COD suppliers — including us — accept credit cards and online payment. You can place your order from your phone, specify the exact number of gallons you want, and schedule delivery without talking to anyone. The oil that arrives is the same #2 fuel oil your furnace has always run on.
One thing worth noting for Nassau County homeowners interested in eco-friendly options: we also offer low-sulfur heating oil and Bioheat® blends. Bioheat® is a biodiesel-blended fuel that burns cleaner than standard #2 oil, and New York State offers a 20-cent-per-gallon tax credit for homeowners who use it. That's a meaningful offset on the cost side, and it's worth factoring in if you're comparing total annual fuel costs.
Discount Fuel Oil Prices on Long Island: What You Save With COD
The savings from choosing COD over a full-service contract are real and specific. On Long Island, COD delivery typically runs $0.50 to $0.90 less per gallon than full-service contract pricing. Over a 100-gallon fill, that's $50 to $80 back in your pocket. Over a full heating season — which for a Nassau County home typically means 800 to 1,000 gallons — the difference can be $400 to $900 annually.
But the per-gallon price isn't the only number that matters. The total cost of a heating oil delivery depends on a few other things, and this is where some suppliers make up the margin they gave back on the per-gallon rate.
Hidden Fees in Heating Oil Contracts: What to Watch For
If you've ever been on a full-service heating oil contract and gotten a bill that didn't match what you expected, you're in good company. The industry has a well-documented history of fees that don't surface until after the relationship is established — and by then, getting out can cost you money too.
The most common ones to watch for: cancellation fees (some companies charge $50 or more if you cancel an order after it's placed, or terminate a contract before the season ends), fuel surcharges (a per-delivery fee tacked on separately from the per-gallon price), price protection plan charges (some companies charge a fee to participate in a program that's supposed to cap your price — read the fine print on what that cap actually covers), and automatic renewal clauses (contracts that roll over into the next season unless you actively cancel within a specific window).
None of these fees are inherently illegal, but they're also not always disclosed prominently. The practical effect is that a quoted per-gallon price from a contract company and a quoted per-gallon price from a COD company are not always apples-to-apples comparisons.
With our COD and will-call service, there are no contracts and no extra fees. The price you see when you order online is what you pay. You specify the exact number of gallons you want — you're not locked into a "fill it up" model where the driver decides how much goes in — and you pay online at the time of ordering. No surprises at delivery, no annual renewal to remember to cancel.
How to Evaluate a COD Heating Oil Supplier in Nassau County
Price matters, but it's not the only thing worth checking before you place your first order with a new supplier. Here's what actually separates reliable operators from the ones who give the category a bad reputation.
The first thing to look for is whether the company publishes its price — or at least makes it easy to get a quote — before you have to call or register. A supplier that won't show you a price until you've created an account or spoken to a salesperson is not making your life easier. Transparency at the quote stage is a reasonable baseline expectation.
Second, check the minimum order. The market standard for COD delivery on Long Island is around 100 gallons. Some companies set higher minimums, which can be inconvenient if your tank is half-full and you want to top off before a storm.
Third, look at years in operation and third-party ratings. This is a category where longevity means something. A company that's been operating on Long Island since 1976 — nearly five decades — has weathered fuel crises, price spikes, supply disruptions, and every kind of Long Island winter there is. We hold an A+ rating from the Better Business Bureau, which is a verifiable, third-party signal that complaints get handled and standards are maintained.
Fourth, check whether you can order online and whether a mobile app is available. For homeowners who work full-time, travel frequently, or just don't want to sit on hold to place a fuel order, this matters. We offer online ordering with exact gallon specification and payment, plus a mobile app available on both iOS and Android.
Finally, confirm the service area covers your specific part of Nassau County. Some COD companies only serve portions of the county — central and western Nassau, for instance — which can leave homeowners in Oyster Bay, Hicksville, Bethpage, or eastern Nassau without coverage. We serve all of Nassau County as well as Suffolk County, so wherever you are on Long Island, you're not a geographic edge case for us.
Getting a Fair Price on Heating Oil in Nassau County Starts With Knowing What to Ask
The bottom line for Nassau County homeowners: COD heating oil is the same quality fuel you've always used, at a price that reflects today's market rather than a contract negotiated months ago. Current prices on Long Island run roughly $2.89 to $3.49 per gallon, and choosing COD over a full-service contract can save you $400 to $900 over a full heating season — provided you're comparing total costs, not just the per-gallon headline rate.
The questions worth asking any supplier are simple: What is the per-gallon price today? Are there any delivery fees, surcharges, or cancellation penalties? What's the minimum order? Can I order online and specify exactly how many gallons I want?
If you're ready to place an order or just want to know today's price without any commitment, OK Petroleum Distribution makes it straightforward. You can order online, pay online, and specify your exact gallon amount — or call us at (631) 321-0549 if you'd rather talk it through. We've been doing this on Long Island since 1976, and keeping it simple is part of how we've stayed here.
