Diesel fuel can be used in a fuel oil furnace, but only as a temporary solution. While diesel and heating oil are chemically similar, diesel burns hotter than traditional heating oil, which can cause lasting damage to a heating unit if used for longer than a few days at a time. Diesel also produces more soot, which can lead to increased buildup and frequent maintenance. Additionally, diesel is typically more expensive than heating oil due to different taxation.

What You'll Learn
Diesel is a good short-term substitute for heating oil
Diesel fuel can be used as a substitute for heating oil in emergencies. However, it is not suitable for long-term use. Heating oil, also known as a "kerosene mix" or "home heating oil winter blend", is a combination of No. 2 and No. 1 fuel oil. It has a lower viscosity, making it more efficient for home heating. It is also taxed at a lower rate than diesel fuel.
Diesel and heating oil are derived from the same distillation process, but they are not identical. Diesel burns hotter than heating oil, which can be beneficial for extremely cold nights. However, over time, this additional heat can wear down components more quickly, shortening the lifespan of your furnace. Diesel also produces more soot than heating oil, which can lead to increased soot buildup and more frequent maintenance.
Due to these differences, it is important to understand when and how to use diesel fuel as a substitute for heating oil. Firstly, ensure that your furnace is turned off before adding any fuel. Locate the fill pipe, which is where you will add the diesel fuel. Use a clean container to pour the diesel fuel into, and then carefully pour it into the fill pipe. Once you have added the diesel, turn your furnace back on and check for proper operation.
It is also important to note that diesel fuel is typically more expensive than heating oil. Therefore, while diesel can be a reliable substitute in an emergency, it is not a cost-effective long-term solution.

Diesel burns hotter than heating oil, which can damage the furnace over time
While diesel fuel can be used as a substitute for heating oil in a fuel oil furnace, it is not recommended as a long-term solution. This is primarily because diesel burns hotter than heating oil, which can damage the furnace over time.
Diesel fuel and heating oil are chemically similar, and diesel can be used to keep your furnace running in an emergency. For instance, if you run out of heating oil and need heat fast, diesel is one of the most common heating oil substitutes. However, it should only be used as a temporary solution, as prolonged use can lead to wear and tear on your furnace.
Diesel burns slightly hotter than heating oil, which can be beneficial on extremely cold nights. However, over time, this additional heat can wear down components and shorten the lifespan of your furnace. Diesel also produces more soot than heating oil, which can lead to increased soot buildup and the need for more frequent maintenance.
In addition, diesel is typically more expensive than heating oil, and it is taxed differently, making it a less economical long-term option. Therefore, it is important to return to regular heating oil as soon as possible.
If you need to use diesel fuel in your furnace temporarily, be sure to follow the proper safety procedures. Turn off your furnace, locate the fill pipe, and use a clean container to pour the diesel fuel into the tank.

Diesel is more expensive than heating oil
While diesel fuel can be used as a substitute for heating oil in emergencies, it is not designed for long-term use. Diesel burns hotter than heating oil, which can be beneficial for extremely cold nights, but this additional heat can also wear down components more quickly, shortening the lifespan of your furnace. Diesel also produces more soot than heating oil, leading to more frequent maintenance.
In terms of cost, diesel is typically more expensive than heating oil. This is partly due to tax regulations. Heating oil, also known as a "kerosene mix" or "home heating oil winter blend", has a reduced tax status due to its essential role for consumers. To distinguish it from higher-taxed diesel fuel, heating oil is tinted with red dye. Diesel fuel used for public road vehicles remains untinted and has a light green colour. Diesel fuel may be more expensive than heating oil at certain times, but this can change during the winter when the demand for heating oil increases.
To illustrate the cost difference, one user in Connecticut reported that their contract price for heating oil was $1.93 per gallon, while diesel fuel in the same state was $5.50 per gallon. Another user in the same state noted that heating oil was about $4 per gallon back in 2008.
In summary, while diesel can be used as a substitute for heating oil in a pinch, it is not a cost-effective long-term solution. The higher cost of diesel, combined with its potential to wear down furnace components more quickly, makes it a less economical choice compared to heating oil.

Diesel may produce more soot than heating oil
Diesel fuel can be used in a fuel oil furnace in emergencies or as a short-term substitute when you are out of heating oil. However, it is important to note that diesel burns hotter than heating oil, which can cause wear and tear on your furnace over time, shortening its lifespan. Diesel also tends to be more expensive than heating oil.
One of the key differences between diesel and heating oil is that diesel can produce more soot than heating oil. This increased soot buildup can lead to more frequent maintenance of your furnace. Therefore, it is crucial to ensure proper ventilation when using diesel fuel to keep your heating system well-ventilated. Regularly checking your furnace for correct and safe operation is essential.
The additional heat produced by diesel fuel can be beneficial during extremely cold nights, but it can also accelerate the wear and tear of your furnace components, making it a less economical long-term solution. Diesel fuel is typically more expensive than heating oil due to different taxation, and it may not be readily available in large quantities.
In summary, while diesel fuel can be a temporary solution when you run out of heating oil, it should not be used as a long-term substitute due to the potential for increased soot buildup, higher costs, and possible damage to your furnace over time. Returning to regular heating oil as soon as possible is recommended.

Diesel can be safely stored for up to six months
Diesel fuel can be safely stored for up to six months without any additives. However, it is important to note that diesel fuel begins to degrade as soon as it leaves the refinery due to oxidation, a chemical reaction that occurs when diesel fuel is introduced to oxygen. This reaction results in the formation of high acid values and the development of unwanted gum, sludge, and sediment, which can corrode the storage tank and clog filters.
To prolong the shelf life of diesel fuel and prevent contamination, it is recommended to use biocides to inhibit bacterial and fungal growth, which thrive at the water-diesel interface. Additionally, preventing or eliminating biofilm, a sludge-like mass that forms at the diesel-water interface, is crucial as it can reduce the effectiveness of biocides.
While diesel fuel can be stored for up to six months, it is not recommended as a long-term substitute for heating oil in a fuel oil furnace. Diesel burns hotter than heating oil, causing components to wear down faster and shortening the lifespan of the furnace. It also produces more soot, leading to increased maintenance requirements. Furthermore, diesel fuel is typically more expensive than heating oil.
Therefore, while diesel can be safely stored for up to six months and used as an emergency substitute for heating oil in a fuel oil furnace, it is not advised for prolonged use due to potential damage to the furnace and higher costs. It is essential to return to regular heating oil as soon as possible to ensure the optimal performance and longevity of the furnace.
