What You'll Learn
Diesel fuel and heating oil are very similar
While diesel fuel can be used as a substitute for home heating oil in emergency situations, it is not suitable for long-term use. Diesel fuel and heating oil are indeed very similar, as they are both derived from crude oil and have similar boiling points. They are both classified as distillate fuel oils, meaning they are cleaner and contain fewer contaminants than the residual heavy fuel oils used in industry and power generation.
The term "diesel" refers to the combustible that powers diesel engines, which are frequently used in automobiles, trucks, buses, and other motorized equipment. Diesel has a higher density and more efficient combustion than gasoline, and it is also less flammable, making it a popular choice for industrial and commercial applications. Similarly, heating oil, also known as "fuel oil", is a combustible derived from crude oil that is often used for residential heating. In Quebec, "fuel oil" is specifically referred to as "mazout" in French.
The main difference between diesel fuel and heating oil lies in their specific additives and intended applications. Heating oil contains additives to prevent sludge formation during extreme cold weather, making it suitable for residential and commercial heating systems. On the other hand, diesel fuel contains additives to improve its performance in diesel engines. Additionally, tax regulations differentiate the uses and taxation of heating oil and diesel fuel. Heating oil enjoys a reduced tax status and is tinted with red dye to distinguish it from higher-taxed diesel fuel.
It is important to note that diesel burns hotter than conventional heating fuel, which can result in lasting damage to a heating unit if used for extended periods. Therefore, while diesel fuel can be a temporary solution in an emergency, heating oil is still the better choice for long-term use in a home heating system.

Diesel is more expensive than heating oil
While diesel fuel can be used as an emergency substitute for heating oil, it is not suitable for long-term use. This is because diesel is more expensive than heating oil.
Firstly, diesel and heating oil are both derived from crude oil and are physically similar. However, they are distinguished by key differences in use, regulation, and environmental impact. Diesel is primarily used for transportation, construction machinery, agricultural vehicles, and off-road vehicles. On the other hand, heating oil is optimised for residential and commercial heating systems.
Secondly, the taxation of diesel and heating oil differs. Heating oil enjoys reduced tax status due to its essential role for consumers. It is tinted with red dye to distinguish it from higher-taxed diesel fuel. This higher tax on diesel fuel contributes to its higher price compared to heating oil.
Thirdly, the demand for diesel and heating oil can also impact their relative prices. During the winter, the demand for heating oil increases, which can make diesel the more expensive option. Conversely, the demand for diesel may be higher during other seasons, affecting its availability and price.
Finally, while diesel can be used as a temporary heating oil alternative, prolonged use can damage the heating unit as it burns hotter than conventional heating fuel. Therefore, it is recommended to limit diesel usage to 5-10 gallons per day for several days until heating oil can be obtained.

Diesel burns hotter than heating oil
While diesel can be used as a substitute for home heating oil in an emergency, it is not recommended for long-term use as it burns hotter than conventional heating oil. Diesel fuel lacks dye and is taxed for on-road use, while heating oil is dyed red and is exempt from on-road taxes. This tax difference makes diesel more expensive than heating oil.
Diesel has a higher combustion temperature than heating oil. This means that while short-term use of diesel won't damage your heating unit, prolonged use will cause lasting damage to the system as it was not built to endure higher temperatures. Diesel also has a lower flashpoint than heating oil, making it easier to catch fire.
Heating oil systems are designed to shut down at critical levels before the tank completely runs out of oil. This is a safety feature to protect the furnace from working without oil, which can cause significant damage. Running on low or no oil occasionally or for a short time may not damage the furnace, but running without oil frequently or for a long time can damage the filter, oil pump, and oil line.
If you are considering using diesel as a substitute for home heating oil, it is important to follow proper safety procedures to prevent accidents. Diesel should be stored in correctly coloured containers—usually yellow gas cans. It can be safely stored for up to six months before it degrades and becomes unsafe to use. Additives can help extend the lifespan of diesel, but they have limitations and required treatments.

Diesel is a good short-term alternative
If you are running low on heating oil, diesel can be a good stop-gap solution. First, you should verify that you are actually out of heating oil by checking the float gauge on the tank. If you are out of heating oil, you can locate the fill pipe on the outside of your house and pour 5-10 gallons of diesel down the pipe. You should wait 5-10 minutes for any sediment to settle and then press the reset button on your burner.
Diesel is a good short-term solution because it can be safely stored for up to six months before it degrades. However, it is more expensive than heating oil and is taxed differently, so be sure to check that you actually require an alternative before purchasing.
There are other ways to prevent your heating oil from running out. For example, replacing the fuel oil line with a larger one can help to keep the oil flowing during cold weather. You can also add anti-gel treatments to your heating oil to prevent the wax from plugging up the filters and restricting the amount of fuel available for combustion.

Diesel anti-gel additives are useful
Diesel anti-gel additives are extremely useful in preventing clogged fuel filters and fuel lines during the winter months. They are a must for treating diesel fuel for winter. Diesel anti-gel additives work by lowering the cold filter-plugging point (CFPP) of diesel fuel. As the temperature drops, wax crystals in the diesel fuel drop out of suspension, solidify, and stick together, clogging fuel lines and causing issues for diesel engines. Diesel anti-gel additives prevent this by significantly reducing the point at which wax in diesel fuel solidifies and keeping the wax dispersed.
Diesel anti-gel additives are also useful in improving the quality of standard diesel fuel. They improve detergency, stability, lubricity, and winter operability, and boost the fuel's cetane number. They also act as a fuel conditioner, providing lubricity, preventing deposits, and eliminating smoking and rough idling. Diesel anti-gel additives are safe to use in all diesel engines, including marine, semi-truck, construction, agriculture, RV, and racing engines.
In addition to their use in vehicles, diesel anti-gel additives can also be used in home heating oil systems. Home heating oil and diesel fuel are similar, both classified as #2 distillate fuel oils. Diesel anti-gel additives can help prevent gelling issues in home heating oil systems during cold weather, keeping the wax dispersed and out of the trouble zone. This is a cost-effective preventive maintenance measure, as it is cheaper than the old-school solution of using kerosene with the heating oil.
Overall, diesel anti-gel additives are a useful and essential tool for preventing fuel gelling issues in both vehicles and home heating oil systems during cold weather. They improve the performance and longevity of diesel engines and heating systems, making them a valuable investment for anyone relying on diesel fuel or heating oil during the winter months.
