Most Nassau County homeowners don't think about heating oil until the tank is running low or the bill comes in higher than expected. Then the questions start. Why did the price jump? Why does my neighbor seem to pay less? Why am I locked into this delivery schedule I never really understood?
The answers aren't complicated — but they're rarely explained clearly. This page is here to change that. We'll walk through what actually drives heating oil prices on Long Island, what you can do to pay less, and how to choose a delivery model that actually works for your household.
Heating Oil Prices Today: What Moves the Market
Heating oil prices aren't set by your local supplier. They move based on a chain of factors that starts thousands of miles away and ends at your tank. The single biggest driver is crude oil. Since heating oil is a refined petroleum product, when crude oil prices rise — whether because of an OPEC production cut, a geopolitical conflict, or a refinery disruption — your per-gallon price follows.
Beyond crude oil, approximately 37% of what you pay per gallon goes toward distribution and marketing costs, and another 15% covers refinery processing. That's more than half your bill before a single drop of oil is burned. Add in Nassau County's dense suburban delivery infrastructure, and you start to understand why home heating oil prices here run meaningfully higher than the national average.
Heating Fuel Prices in Nassau County: Why Long Island Costs More
The national average for heating oil hit approximately $2.45 per gallon in early 2025, according to the U.S. Energy Information Administration. If you're a Nassau County homeowner, that number probably sounds low compared to what you've been paying. That gap is real, and it's not a coincidence.
Long Island sits in a regional pricing zone tracked separately by NYSERDA — Nassau and Suffolk Counties together — and delivered prices here have ranged from $4.17 to $4.59 per gallon depending on the supplier and order size. The reasons come down to local distribution costs, the density of the delivery market, and the sheer volume of demand concentrated on a relatively small geographic footprint.
Here's the part that often surprises people: roughly 59% of Nassau County homes run on heating oil, compared to less than 9% of homes nationally. That's not a preference — it's a structural reality rooted in when these communities were built. The median year of home construction here is 1955. The Cape Cods, split-levels, and ranch homes that define Levittown, Baldwin, Bellmore, and dozens of other Nassau County communities were built at a time when natural gas infrastructure hadn't reached most of Long Island. Oil-fired heating systems were the default installation, and for millions of homeowners, they still are.
That concentration of demand, combined with the logistics of delivering fuel across a dense suburban grid, keeps Long Island prices above the national average. It's not that suppliers are gouging — it's that the structural costs of serving this market are genuinely higher. Understanding that is important, because it shifts the question from "why are prices so high?" to "how do I make sure I'm not paying more than I have to?"
The Hidden Cost Most Automatic Delivery Customers Don't Know About
Here's something that doesn't get talked about enough: automatic delivery customers on Long Island routinely pay $0.40 to $0.60 more per gallon than will-call customers. That's not a rounding error. At 1,000 gallons per heating season — a reasonable annual figure for a Nassau County home — that gap translates to $400 to $600 per year, paid quietly, without most customers ever realizing it.
Automatic delivery made sense as the default option when it was introduced. The idea was simple: a supplier monitors your usage, models your consumption based on temperature data, and delivers before you run out. No phone calls, no watching the gauge. For busy households, that convenience has real value. But the price premium attached to it is rarely explained upfront, and many homeowners signed up for automatic delivery years ago without understanding what it was actually costing them.
The will-call model — where you order when you want, specify the exact number of gallons, and pay without a contract — puts that money back in your pocket. It requires a bit more attention to your tank level, but for homeowners who are reasonably engaged with their home's systems, it's a straightforward way to pay the lower rate without giving up reliable service.
At OK Petroleum Distribution, we offer both. Our automatic delivery program uses degree-day consumption modeling and predictive algorithms to calculate when your tank will need a refill — not just a fixed calendar schedule that may or may not match how your household actually uses fuel. And our will-call service comes with no contracts and no extra fees, so you can order exactly what you want, when you want it, and pay online through our website or mobile app. The flexibility to choose — and to switch between the two as your situation changes — is something most suppliers on Long Island simply don't offer.
Heating Oil vs. Natural Gas vs. Propane: The Honest Comparison
A lot of Nassau County homeowners are asking whether they should stay on oil or make a switch. It's a fair question, and it deserves a straight answer — not a sales pitch in either direction.
The short version: each fuel has real advantages, and the right choice depends on your home's infrastructure, your budget for conversion, and what's actually available in your neighborhood. Here's what the comparison actually looks like.
Oil Heating vs. Natural Gas: What the Numbers Actually Show
Natural gas is often cheaper per BTU than heating oil in markets where it's readily available. On a per-unit cost basis, gas frequently comes out ahead — and modern gas furnaces can reach efficiency ratings of up to 98% AFUE, compared to approximately 87% AFUE for the best oil furnaces. Those are real differences worth acknowledging.
But here's what the straightforward comparison leaves out: many Nassau County neighborhoods don't have natural gas lines running to individual homes. Converting from oil to gas isn't just a matter of swapping out your furnace. It can require new gas mains at the street level — an infrastructure investment that depends on the utility, not you — plus a home-level conversion that typically runs $5,000 to $15,000 or more, covering a new furnace or boiler, piping, and installation. For homeowners in areas where gas is already available at the curb, the conversion math may eventually work out. For the large portion of Nassau County where it isn't, the question is largely moot.
Heating oil also carries a meaningful energy density advantage. A gallon of No. 2 heating oil contains approximately 138,500 BTU of energy. That's a significant figure when you're trying to heat a 1,500-square-foot split-level through a Long Island winter. The efficiency gap between oil and gas systems is real, but oil's BTU density partially offsets it — meaning a direct per-gallon price comparison doesn't capture the full picture. When you factor in what each fuel actually delivers in usable heat, the gap narrows.
Oil vs. Propane: Home Heating Costs Compared
Propane is sometimes pitched as a cleaner, simpler alternative to heating oil — and it does burn more cleanly, which matters for furnace maintenance and indoor air quality. But the cost of propane vs. heating oil is more complicated than it appears at first glance.
Propane contains approximately 91,500 BTU per gallon, compared to 138,500 BTU for heating oil. That's roughly 34% less energy per gallon. So even when propane's per-gallon price looks competitive, you're buying less heat per dollar spent. To produce the same amount of warmth as a gallon of heating oil, you need more propane — which closes the apparent price gap considerably.
There's also the question of seasonal price volatility. Propane prices tend to spike sharply in winter when demand surges, sometimes dramatically. Heating oil prices are also seasonal, but the Long Island market has a deeper, more established supply infrastructure that tends to moderate the worst swings. And with a price cap plan — which locks in a maximum per-gallon rate for the season — oil customers can protect themselves against winter spikes without giving up the benefit if prices fall below the cap.
Modern propane furnaces can reach high efficiency ratings, and propane does produce fewer particulates than older oil systems. If you're weighing the switch, those are legitimate factors. But the conversion costs are real, and the per-BTU economics often look less favorable once you run the actual numbers. For Nassau County homeowners with a well-maintained oil system and access to low-sulfur or bioheat blends — which burn significantly cleaner than older fuel formulations — staying on oil frequently makes more financial sense than the marketing around propane alternatives suggests.
How to Get the Best Price on Heating Oil in Nassau County
The homeowners who consistently pay less for heating oil aren't doing anything exotic. They understand the delivery model they're on, they know what drives prices, and they've chosen a supplier that gives them flexibility rather than locking them in. Buying earlier in the season — before peak winter demand pushes prices up — helps. So does knowing the difference between automatic delivery and will-call, and making a deliberate choice between the two rather than defaulting to whatever you signed up for years ago.
If you haven't compared prices or revisited your delivery arrangement recently, it's worth doing. The $0.40 to $0.60 per-gallon gap between automatic delivery and will-call pricing is real, and it compounds over an entire heating season.

FREQUENTLY ASKED QUESTIONS
What is the heating oil cost per gallon right now on Long Island?
Delivered heating oil prices in Nassau and Suffolk Counties have ranged from approximately $4.17 to $4.59 per gallon depending on the supplier, order size, and payment method. Prices shift frequently based on crude oil markets and seasonal demand, so the best way to get today's rate is to check directly with your supplier or use a local price comparison tool. Will-call customers who order on-demand typically pay $0.40 to $0.60 less per gallon than those on automatic delivery programs.
Is propane cheaper than oil?
Not necessarily — and the comparison is more nuanced than it looks. Propane contains about 91,500 BTU per gallon versus approximately 138,500 BTU for heating oil, which means you need more propane to produce the same amount of heat. Even when propane's listed price per gallon appears lower, the per-BTU cost often comes out comparable or higher. Propane prices also tend to spike sharply in winter. For most Nassau County homeowners with an existing oil system, the economics of switching to propane rarely pencil out as clearly as the pitch suggests.
Is propane better than oil for home heating?
It depends on what you mean by "better." Propane burns more cleanly and produces fewer particulates, which can reduce furnace maintenance over time. Modern propane systems can also reach higher efficiency ratings than oil furnaces. But heating oil has superior energy density, a well-established Long Island supply infrastructure, and — with today's low-sulfur and bioheat blends — burns significantly cleaner than older formulations. For homes already set up for oil in Nassau County, the combination of conversion costs and per-BTU economics makes propane a less clear-cut upgrade than it's often presented as.
Is oil heating cheaper than gas?
In markets where natural gas is readily available, gas tends to be cheaper per BTU — especially with high-efficiency gas furnaces. But in Nassau County, natural gas access is limited in many neighborhoods, and the cost of converting a home from oil to gas typically runs $5,000 to $15,000 or more. For homeowners where gas isn't available at the curb, the comparison is largely academic. For those where it is, the conversion math depends heavily on current fuel prices, your home's energy consumption, and how long you plan to stay in the house.
Is oil heat more expensive than gas?
On a straight per-BTU comparison in areas with gas access, oil heat often runs somewhat higher. But heating oil's energy density — approximately 138,500 BTU per gallon — means you're getting a lot of usable heat per delivery. And the cost of converting to gas, combined with the installation timeline and neighborhood infrastructure requirements, means the breakeven point for switching is often further out than homeowners expect. If you're in Bellmore, Baldwin, Mineola, or another Nassau County community where oil heat is the established norm, the real question is less about oil vs. gas and more about which oil supplier and delivery model is actually working in your favor.
Is gas or oil heat better?
Neither is universally better — it depends on your home, your neighborhood's infrastructure, and your priorities. Gas systems can achieve higher efficiency ratings and tend to have lower per-BTU fuel costs where gas is available. Oil systems deliver more energy per gallon, have a mature Long Island supply chain behind them, and don't require the infrastructure investment that gas conversion demands. For Nassau County homeowners in post-war homes that were built for oil, the more practical question is often how to get the most out of the system you already have — through better fuel quality, smarter delivery options, and a pricing arrangement that doesn't quietly cost you hundreds of dollars a year.
Where can I find domestic heating oil suppliers near me in Nassau County?
Several local and regional suppliers serve Nassau County, ranging from large discount-focused operations to full-service companies with multiple delivery and payment options. When comparing domestic heating oil suppliers, price per gallon is the obvious starting point — but delivery reliability, contract terms, payment flexibility, and how long a company has been operating in the area all matter. A supplier offering a slightly lower per-gallon rate but with a contract that locks you in for the season may not actually be the better deal once you factor in the lack of flexibility. We've been serving Nassau County since 1976, and we're happy to discuss how our automatic and will-call options compare to what you're currently getting.
