We deliver
Most orders arrive in 1–3 business days. Your price is locked the moment you order.
Why COD heating oil?
COD means you buy oil one delivery at a time. No long-term contract, no automatic deliveries, and no one forcing you to fill the tank.
You decide how many gallons and when — so you stay in control of your budget, and you still get the same quality #2 heating oil a full-service company delivers.

Common questions
Why does checkout say SuffolkOil.com?
SuffolkOil.com is Calderon's secure online ordering system. Your card statement will show SuffolkOil.com.
When will my oil arrive?
Usually within 1–3 business days. No Sunday or holiday deliveries. From Nov 1 to Apr 30, orders placed by 5 PM Friday are delivered Saturday.
My tank didn't take all the oil. When am I credited?
The difference is credited back to the card you used within 15 business days of delivery.
Can I pay the driver in cash?
Yes — someone just needs to be home when the driver arrives.
The price dropped after I ordered. Do I get the lower price?
Prices are locked when you place your order, not at delivery — which also protects you if prices go up.
