What You'll Learn
Diesel fuel is more expensive than heating oil
Diesel fuel can be used as an alternative to heating oil in emergency situations, but it is not a suitable long-term substitute. One of the biggest setbacks of using diesel fuel in your home heating oil tank is that it is taxed differently from heating oil, making it more expensive. Diesel fuel used for public road vehicles is untinted, whereas diesel and heating oil are both tinted with red dye for tax purposes. Heating oil enjoys reduced tax status due to its essential role for consumers.
Heating oil and diesel fuel are derived from crude oil and have similar boiling points. However, heating oil is a combination of No. 2 and No. 1 fuel oil, giving it a lower viscosity that makes it more efficient for home heating. Diesel fuel, on the other hand, is primarily used for construction machinery, agricultural vehicles, and off-road vehicles.
The costs of heating oil and diesel fuel can vary depending on supply and demand. While diesel fuel may be more expensive than heating oil at certain times, this can change during the winter when demand for heating oil increases. Purchasing heating oil ahead of the cold weather can help manage fluctuating prices.
It is important to note that diesel has hotter combustion than conventional heating fuel, which can result in lasting damage to your heating system over time as it is not built to withstand higher temperatures. Diesel fuel can be safely stored for up to six months before it deteriorates, and you can use additives to extend its life. However, there are limitations and necessary treatments associated with using additives.

Diesel is a good temporary alternative to heating oil
Firstly, check if your tank is at a critical level or empty. Many tanks have feed lines that run from the top downwards, so you may run out of fuel even before the tank is fully empty. Once you've verified that your tank is below critical levels or empty, you can start using diesel as a short-term replacement.
Secondly, diesel is taxed differently and is more expensive than heating oil. So, before switching to diesel, it is recommended to inspect your oil tank to ensure that you need an alternative fuel. You can check the oil level by inspecting the floating gauge, which floats on the oil and indicates how empty or full your tank is.
Thirdly, diesel burns at a higher temperature than heating oil. This isn't an issue if used for a few days, but prolonged use can cause lasting damage to your heating system as it is not designed to withstand higher temperatures. To preserve your tank's service life, limit your diesel consumption to 5 to 10 gallons per day for several days until your heating oil delivery arrives.
Finally, when it comes to storing diesel, it can be safely stored for up to six months before it deteriorates. Additives can extend the life of diesel, but they come with limitations and necessary treatments. Proper disposal of diesel can be done through local recycling or hazardous waste collection centers.

Diesel fuel is flammable and requires careful storage
Diesel fuel is a flammable liquid that requires careful storage to mitigate potential hazards. Its flammability is determined by its flash point—the minimum temperature at which the vapours emitted by the liquid can be ignited at its surface. Diesel fuel generally has a flash point between 52°C and 93°C, with some sources stating a narrower range of 60°C to 93°C. According to the National Fire Protection Association (NFPA), diesel fuel is considered a Class II combustible liquid, with a flash point between 100°F and 140°F (38°C and 60°C).
When diesel fuel is blended with ethanol (E-diesel) to reduce emissions, the flash point can drop to around 20°C, classifying it as a flammable liquid and requiring additional precautions to manage fire and explosion hazards.
To ensure safe storage, diesel fuel must be kept in approved containers, cabinets, and handling equipment. Type II safety cans feature two openings: one for filling and the other for dispensing, providing a safer and more controlled pour. For construction or transportation purposes, DOT safety cans feature roll bars that ensure safe closure and spout protection. Additionally, safety cabinets are available to protect flammable and combustible materials from ignition sources. These cabinets feature self-latching doors to secure their contents and provide maximum protection in the event of a fire.
It is crucial to adhere to storage regulations and size bulk diesel storage tanks appropriately. The sizing depends on factors such as the classification of the emergency power supply system (EPSS) and the associated standards outlined by organizations like the National Fire Protection Association. For example, a Class 48 EPSS is expected to operate for at least 48 hours without refilling the bulk tank.
While diesel is less flammable than gasoline, it still poses a fire risk if not properly stored and handled. By understanding the flash point of the specific type of diesel fuel and following the recommended storage guidelines, the hazards associated with diesel fuel can be effectively managed.

Diesel fuel temperature must be controlled to prevent damage
Diesel fuel can be used as an alternative to heating oil in an indoor tank. However, it is more expensive and has a higher combustion temperature, which can cause damage to the heating system over time. Therefore, it should only be used for a short period, with a recommended limit of 5 to 10 gallons of diesel per day for several days.
Diesel fuel has a flash point, the minimum temperature at which it emits sufficient vapours to be ignited. The flash point determines whether diesel will burn or explode. Diesel fuels generally have a flash point between 52 °C and 93 °C. Diesel fuels with a flashpoint below 60 °C are classified as flammable liquids, while those above 60°C are combustible liquids. Flammable liquids have a lower flash point and boiling point than combustible liquids, making them more volatile. However, both types of liquids can burn and explode, so controls must be implemented when handling and storing diesel fuel.
The flash point of diesel fuel is important for understanding its storage requirements. Diesel fuel blending affects its classification and tank vent design. When blended with ethanol (E-diesel) to reduce emissions, diesel fuel has a low flash point of about 20°C, making it a flammable liquid that requires careful management of fire and explosion hazards.
Overall, diesel fuel temperature control is crucial for safe and efficient usage. By understanding its flash point, blending characteristics, and temperature limits, potential hazards can be mitigated, ensuring the fuel's compatibility with storage tanks and injectors.
