#2 fuel oil is a crucial heating oil for home heating needs. It is the most commonly used fuel oil because it generates the largest amount of heat. It is chemically similar to diesel fuel but is stained with a reddish dye. The colour of the oil in your heating oil tank can vary depending on the type of oil you use. For instance, untaxed diesel fuel is often dyed red, while taxed diesel fuel has a natural light green tone. Kerosene, another common heating oil, is the lightest fuel oil and has a clean burn, making it safe for indoor use.

What You'll Learn
No. 2 fuel oil is dyed red
No. 2 fuel oil is a product of the refinement of crude oil. It is the most commonly used fuel oil because it generates the largest amount of heat. This is why it is the industry standard for home heating oil.
The red dye in No. 2 fuel oil also distinguishes it from taxed diesel fuel, which does not contain any dye and has a natural light green colour. Untaxed diesel fuel, which is dyed red, is used in off-road vehicles and construction equipment.
No. 2 fuel oil is chemically similar to diesel fuel, and both are structurally comparable to oils commonly used for heating buildings. They share similar molecular structures, being made up of elaborate combinations of aromatic and aliphatic hydrocarbon molecules.

Home heating oil vs on-road diesel fuel
Home heating oil and on-road diesel fuel are both derived from crude oil, but they have distinct characteristics and applications. Understanding these differences is crucial for selecting the appropriate fuel for your heating system or vehicle.
Home heating oil, also known as No. 2 fuel oil, is the most common type of oil used in homes for heating purposes. It is specifically designed for furnaces, boilers, or water heaters. This oil has a high viscosity and boiling point, allowing it to generate a large amount of heat. To distinguish it from higher-taxed diesel fuel, it is tinted with red dye and enjoys reduced tax status due to its essential role for consumers. Heating oil is crucial for keeping homes warm during winter, especially in regions with cold climates, such as the Northeastern United States.
On-road diesel fuel, on the other hand, is primarily used for vehicles driven on public roads, such as cars and trucks. This type of diesel remains untinted and typically has a light green colour. It is also used in construction machinery, agricultural vehicles, and off-road vehicles. Untaxed diesel fuel, which is often used in off-road capacities, is dyed red to differentiate it from fuel intended for on-road use. This untaxed diesel is more expensive due to the included taxes, but it is considered eco-friendly because of its low sulfur content.
While home heating oil and on-road diesel fuel share some similarities, they are not interchangeable. Using diesel fuel as a long-term substitute for heating oil or vice versa is not recommended due to differences in additives and intended applications. Heating oil, with its high sulfur content, can harm vehicles or equipment if used in place of diesel fuel. Additionally, it is illegal to use home heating oil in a car or truck with a diesel engine.
In summary, home heating oil and on-road diesel fuel serve different purposes. Home heating oil is essential for residential heating systems, especially during winter, while on-road diesel fuel is designed for vehicles driven on public roads and certain off-road applications. It is important to select the appropriate fuel for your specific needs to ensure the safe and efficient operation of your heating system or vehicle.

No. 2 fuel oil is the most common
No. 2 fuel oil is the industry standard for home heating and is widely used in the country. It generates the largest amount of heat, as can be seen from its British Thermal Unit (BTU) rating. This makes it crucial for home heating needs, especially during the winter season in certain parts of the US. When it comes to stocking up on home heating oil, many homeowners will need a reliable heating system to stay comfortable and safe during the cold months.
No. 2 fuel oil is also used in combination with other fuel oils. For example, it can be blended with No. 1 fuel oil to create a mixture that is less likely to form sludge in aboveground tanks installed outdoors and exposed to extremely cold weather. The ratio of the blend will depend on various factors, and it is recommended to consult an oil provider for the appropriate mixture. Additionally, No. 2 fuel oil can be mixed with kerosene to produce a cleaner burn.
While No. 2 fuel oil is commonly used for home heating, it is not suitable for indoor use in portable stoves and heaters due to its impure burn. The exhaust fumes it emits can be toxic when breathed in. Therefore, it is typically used outdoors, where the impurities are diluted in the air, making it safer. Kerosene, on the other hand, is derived from the refinement and filtration of No. 1 fuel oil, resulting in a cleaner burn that is safe for indoor use. It is also commonly used during camping trips and power outages for lighting and heating.

Kerosene is a derivative of No. 1 fuel oil
#2 fuel oil is the most commonly used fuel oil. This is because it generates the largest amount of heat. During fuel oil delivery, companies send trucks filled with #2 fuel oil. However, they may inform customers if they have other blends that may be more suitable for their heating oil tank or the current temperatures. For instance, in extremely cold weather, it is best to use a blend of #1 and #2 fuel to create less sludge. Alternatively, #2 fuel oil can be mixed with kerosene, resulting in a fuel that produces a cleaner burn.
Kerosene is a derivative of #1 fuel oil. It is made through the refinement and filtration of #1 fuel oil. As a result, kerosene has a clean burn and is safe to use indoors. It has a low viscosity and boiling point. Kerosene is often used for portable heat sources outdoors or indoors. It is commonly used during power outages or camping trips, as kerosene lamps can provide lighting that can last for long hours.
Kerosene is also the lightest fuel oil. It has a lower viscosity and higher efficiency levels than #1 fuel oil. Kerosene is frequently used as a power source for portable heating units. For example, it is used in new construction sites and other places without furnaces.
#1 fuel oil has a higher viscosity and more impurities than kerosene. It is often used for portable heaters and outdoor heating materials like stoves. However, it cannot be used indoors as it does not produce a clean burn. The exhaust fumes from #1 fuel oil can be harmful when breathed in.

No. 2 fuel oil is chemically similar to diesel
No. 2 fuel oil is widely used for home heating and is considered the industry standard for home heating oil. It is derived from crude oil and is known to generate a large amount of heat when burned. No. 2 fuel oil is chemically similar to diesel, and in some cases, diesel fuel can be used as a substitute for No. 2 fuel oil in home furnaces.
No. 2 fuel oil and diesel fuel have the same chemical composition, but they are typically used for distinct functions. While diesel oils usually have a consistent purpose, No. 2 fuel oil can be used for different reasons in various locations and environments. Diesel fuel is commonly used in vehicles and trucks, while No. 2 fuel oil is primarily used for heating buildings.
In cases of emergency or shortage of No. 2 fuel oil, diesel fuel can be temporarily used in furnaces instead. However, it is important to follow proper procedures when using diesel oil in furnaces. Additionally, diesel fuel is usually more expensive than No. 2 fuel oil, so using it as a substitute should be limited to urgent situations.
The primary difference between No. 2 fuel oil and diesel lies in their intended use and taxation. No. 2 fuel oil is tax-free to keep prices low, as it is considered a vital need for home heating during winter. On the other hand, diesel fuel has road taxes included in its price. This distinction makes No. 2 fuel oil more affordable for homeowners.
While No. 2 fuel oil and diesel have similar chemical compositions, it is important to understand their differences and use them for their intended purposes. Using No. 2 fuel oil in vehicles is illegal, and using diesel oil in furnaces should be done with caution and only when necessary.
