Choosing a delivery plan
The fuel that arrives is the same whichever plan you are on. What changes is how and when you pay for it, and who decides when the truck comes.
Automatic delivery means we track your usage and schedule a fill before you run low, rather than waiting for you to notice.
Pre-buy means paying up front for the season at a rate agreed in advance.
Fixed price means paying as you go at a rate that will not move mid-winter. There are also contract options for clear and dyed diesel, and an annual service contract for heating equipment.

Fuel Product FAQs
Is heating oil the same as diesel?
No, but they’re closely related. Both are middle distillates refined from crude oil, with similar energy content and similar combustion behavior. The differences are in formulation, taxation, and intended use.
Heating oil is formulated for fuel that sits in a tank for months, with additives that resist sludge and maintain stability during long storage. Diesel is formulated for engines, with additives for ignition quality, lubricity, and injector protection. Heating oil is untaxed because it’s an essential heating fuel; on-road diesel carries road tax, which is why the pump price is higher.
Can I put diesel in my heating oil tank if I run out?
In a genuine emergency, yes — but treat it as a short-term bridge, not a plan. Diesel burns acceptably in most oil heating systems and can restore heat until a delivery arrives.
If you do it: add enough to get well above the tank’s pickup line — for most residential tanks that means at least 5 to 10 gallons, since a gallon or two often leaves the burner drawing air. Use clean, approved fuel containers, keep fuel away from any flame or spark, and expect that the system may still need priming and restarting afterward.
Two cautions worth knowing. Diesel from a pump costs meaningfully more per gallon than delivered heating oil because of road tax. And running a tank dry stirs up sediment that can clog the filter or nozzle, so a service call may be needed regardless of what you put in.
Why does heating oil cost less than diesel at the pump?
Tax, mostly. Heating oil is untaxed because it’s classified as an essential heating fuel. On-road diesel carries federal and state road taxes that add substantially to the pump price.
There’s also a delivery-versus-retail difference: heating oil is delivered in bulk to your tank, while diesel is sold through retail stations with their own cost structure. Both prices still move with crude oil, and both rise seasonally as winter demand increases.
