How to Compare Heating Oil Prices (Apples-to-Apples)

April 2026 · 6 min read

Most homeowners who shop for heating oil make the same mistake: they compare the per-gallon price quoted by one dealer against the per-gallon price quoted by another, call it done, and go with the lower number. This works sometimes. But between delivery fees, fuel surcharges, and minimum quantities, the dealer quoting $3.85/gallon can end up costing you more than the dealer quoting $3.92/gallon. Here's how to compare correctly.

Why Per-Gallon Price Alone Is Misleading

A per-gallon price is only one component of what you actually pay. Common add-on charges include:

Delivery surcharge: A flat fee per delivery ($15–$35) or a per-gallon surcharge ($0.05–$0.20/gallon) added on top of the fuel price
Minimum delivery fee: If you order fewer than the minimum (typically 100–150 gallons), some dealers charge a fee
Service contract fee: If the quote bundles a service plan you didn't ask for, the effective cost is higher
Credit card surcharge: Some dealers charge 2–3% extra for credit card payments vs. check

The only number that matters is your effective cost: total invoice ÷ gallons delivered.

The Effective Cost Calculation

Example: Two dealer quotes for 150 gallons

Dealer A: $3.85/gallon + $25 delivery fee = $577.50 + $25 = $602.50 total → $4.02/gallon effective

Dealer B: $3.95/gallon, no separate delivery fee = $592.50 total → $3.95/gallon effective

Dealer B wins by $0.07/gallon despite the higher listed price.

When getting quotes, always ask: "What will my total invoice look like for a 150-gallon delivery?" That forces the dealer to include all fees in a single number you can compare.

Questions to Ask Every Dealer

"What is your per-gallon price today?" — Get the number before proceeding
"Are there any delivery fees or surcharges on top of that?" — Many dealers don't volunteer this
"What is your minimum delivery quantity?" — Relevant if your tank is low
"Is there a different price for automatic delivery vs. will-call?" — Some dealers offer lower prices for will-call customers; others charge more
"Do you charge extra for credit card payments?" — A 3% surcharge on a $600 bill is another $18
"What is your service area for my address?" — Dealers sometimes quote lower prices and then add an out-of-area surcharge when they arrive

What to Look for Beyond Price

Price is important, but it's not the only thing that matters when choosing a dealer:

Minimum order quantity: A dealer who requires 200 gallons minimum is a problem if your tank is only low by 100 gallons
Delivery window: Is it 1–3 days, or 5–7 days? For a will-call customer ordering in January when prices spike, a week-long wait matters
Emergency delivery availability: Does this dealer have an after-hours emergency line? What do they charge for it?
Service bundling: Some dealers offer lower fuel prices if you commit to their service contract. Worth considering if you need an annual tune-up anyway — run the combined math
Price stability: A dealer who quoted you $3.85 today may charge $4.40 next week. Ask whether they honor quotes for a specific delivery window

The market rate check: Before calling any dealer, look up the current EIA weekly retail heating oil price for New England. That's the public benchmark — any dealer charging more than $0.50/gallon above that is on the expensive side. Most competitive dealers will be within $0.20–$0.40 above EIA retail.

Same Fuel, Different Prices

It's worth stating plainly: all No. 2 heating oil from Connecticut-area dealers meets the same state specifications. The fuel that comes out of one truck is chemically identical to the fuel from a competitor's truck. Price differences between dealers reflect their operating costs, margins, and willingness to compete — not differences in fuel quality. A dealer charging $0.40/gallon more than their competitors is not delivering better oil.

Connecticut requires B5 Bioheat (minimum 5% biodiesel blend) for residential heating — all dealers must meet this standard. There is no "premium" heating oil that justifies a significant price premium for a residential customer.

When to Lock In vs. Shop on Spot Price

If you're comparing prices across multiple dealers, you're implicitly a spot-price buyer — you're evaluating the current market. This is the right approach for will-call customers who monitor the tank and order when the price is right. For customers on automatic delivery, you don't get to price-compare on each delivery — the comparison happens when you choose your dealer, and it should factor in the dealer's track record of pricing over multiple seasons, not just one day's quote.
