Any questions please give us a call 631-924-4030


You can expect your delivery in 1-3 business days. We do not deliver on Sundays or Holidays. During the cold and winter months (11/1 to 4/30) orders placed before 5 PM on Friday, will be delivered on Saturday. We do not make Saturday deliveries during the summer months (5/1 to 10/31).

You can expect a credit to be posted back to the card you used to place your order within 15 business days from the date of your delivery.

Prices are set at the time you place your order not when fuel is delivered. You wouldn’t want us to raise the price if it went up after you placed your order, would you?

SuffolkOIL has partnered with Donlon Brothers Heating & Cooling Inc. 631-599-2990 to provide for your heating system needs.

If you elect to pay cash, someone must be home when the driver arrives.

COD fuel is simply purchasing heating oil on a delivery-to-delivery basis. You as the consumer can choose the fuel oil company of your choice and order at your own convenience. With today’s high cost of living, most consumers are on a tighter budget than ever before. It makes economic sense to be in control of your own oil deliveries. You decide how many gallons to order and when you want it.

COD fuel is the same principle as filling up your car at the gas station. Certainly, with all of the choices of gas stations out there, you wouldn’t want to commit yourself to a long term contract with only one. Plus, when you go to the gas station, they don’t force you to top off your tank. You simply stop the pump at your convenience or at a dollar amount that suits your budget at the time COD fuel gives you the same flexibility.

No. In fact, all fuel companies purchase their oil from the same places regardless of how large or small the company is. If you were to visit an oil terminal where fuel companies purchase the oil, you would see a variety of different companies (large and small) waiting in line to load the same oil onto their trucks.

Every oil truck has a meter that prints out the amount of gallons delivered. These meters are inspected and sealed by the County Department of Weights & Measures. Meters are inspected frequently and resealed annually.

SuffolkOil’s fuel prices are less expensive because they do not include a repair service contract or hidden finance charges for monthly billing cycles. Most large companies that offer “free” service contracts must factor in the costs for repair technicians, repair vehicles, truck fuel, burner parts and a myriad of other factors and then add them to the fuel price. Unfortunately, if you do not have burner problems of your own, your hard-earned money is paying to have someone else’s burner repaired.

No. You do not need a service contract to purchase COD fuel, but the choice is yours. Most COD companies have their own service department or work directly with a reliable service company that can offer you a service contract. Some consumers feel that a service contract can offer peace of mind, yet some consumers would rather pay for service as needed just like their oil deliveries.  Please contact Donlon Brothers for any Heating and Cooling needs at 631-599-2990

No. The oil industry is closely monitored by the state. All oil companies must be licensed and properly insured or they will not be able to load their trucks at the oil terminal. Also, the state performs a background check on all applicants prior to receiving a license to deliver oil.

You should have your heating system tuned up once a year by a professional. A properly-serviced system can pay for the price of the tune-up over the course of the heating season in fuel savings and also help prevent untimely breakdowns or other major problems.

I can’t say enough about this company. They go above and beyond to do the right thing. I buy my heating oil as I need. I ran out today and ordered a refill online. After placing the order I called to see if I could get same day delivery. The women that answered the phone already knew my order and address. She said she could not give me an exact time but insured me that I would get my delivery the same day. As promised I had it before the end of the day. These guys are great. I’ve been a happy customer for almost 10 years and will not go anywhere else. They have competitive prices and delver you order quickly.
