Oilheat is competitively priced, environmentally friendly, extremely efficient, safe and very convenient. Oilheat is also dependable, especially when you call on East Coast.


The American Society for Testing and Materials, (ASTM) classifies fuel oils into five basic grades: Numbers 1 – 6.

NUMBER 2 “distillate fuels” are able to be vaporized or distilled at somewhat low temperatures. Very fluid, they move like water at room temperature.

NUMBER 2 OIL is also called #2 Heating Oil. Usually this type of oil is used in space heating oil for private homes.

NUMBER 4 OIL, a hybrid fuel, is a combination of Number 2 Oil and Number 6 Oil in certain proportions required to meet the specifications of equipment that is designed to burn Number 4 oil. Very often, this fuel is used in heating equipment found in schools and smaller buildings. Number 4 Fuel oil has a higher energy generation (BTU) content than Number 2 Oil. It is less fluid at room temperature than Number 2 heating oil, however, neither a heated storage system nor a preheater are needed to assure proper combustion.

NUMBER 6 OIL is the heaviest oil in our product line. With the highest BTU content, we sell more Number 6 Oil than any other product. Large office complexes, residences and industrial building all depend upon East Coast for this thick, black, oil. It does not pour out at room temperature and needs a heated storage area and preheating in order to ensure proper combustion. It has the highest BTU content of all of our products and has its greatest demand in large office, residential and industrial buildings Number 6 oil is the residual product of the refining process after all the “light” products such as gasoline, diesel oil and lubricants have been extracted and is often referred to as “residual fuel oil.” This oil is often used as asphalt in road paving.

DIESEL: Petroleum processors derive a number of different fuels from each barrel of crude oil. In addition to gasoline and heating oil, petroleum refinement also results in a lighter, low-sulfur oil known as diesel. The U.S. Energy Information Administration estimates that diesel provides as much as 7 percent of the energy used in the U.S. and is the second most popular fuel source after gasoline. Diesel fuel was particularly useful for powering commercial generators during Hurricane Sandy, and East Coast Petroleum was one of the few companies in the Tri-State area with plenty of diesel supply to go around!
