What You'll Learn
Diesel is a good emergency substitute for home heating oil
Diesel fuel can be used as an emergency substitute for home heating oil in your oil furnace. Diesel and heating oil are chemically similar, with diesel being slightly more refined. This makes diesel a suitable alternative if you suddenly find yourself without heating oil.
If you are getting low on heating oil, you can use diesel as a substitute until you can get a heating oil refill. Diesel burns hotter than conventional heating oil, which can lead to increased wear and tear on your furnace if used for extended periods. However, for short periods, this is not an issue. It is recommended to use 5-10 gallons of diesel per day for a few days at most.
To use diesel in your furnace, first, turn off your furnace and locate the fill pipe on the outside of your house. Remove the cap and pour the diesel down the fill pipe. Wait 5-10 minutes for any sediment to settle, then press the reset button on your burner. If it does not start, you may need to bleed the lines to release any air in the system, which can be a messy process.
It is important to note that diesel is typically more expensive than heating oil due to different taxation. It is also important to ensure proper ventilation when using diesel, as it can produce more soot than heating oil. Additionally, always use clean containers to avoid contaminants, which can damage your furnace.

Diesel is more expensive than heating oil
In an emergency, diesel fuel can be used as a substitute for heating oil in a home furnace. However, it is not suitable for long-term use. While diesel and heating oil are chemically similar, there are some key differences.
Firstly, diesel is taxed differently from heating oil, which enjoys a reduced tax status due to its essential role for consumers. This means that diesel tends to be more expensive. Secondly, diesel burns hotter and cleaner than standard heating oil, which can lead to increased wear and tear on a furnace's components.
To avoid using diesel fuel as a substitute, it is recommended to check your tank gauge regularly during the colder months, as oil is used more quickly during this time. Ordering smaller amounts of heating oil more frequently can also help to avoid running out.
If you do need to use diesel fuel in an emergency, locate your oil tank's fill pipe on the outside of your house and pour in around 5-10 gallons of diesel fuel. Allow 5-20 minutes for any sediment to settle before restarting your furnace.

Diesel burns hotter than heating oil
Diesel can be used as a substitute for home heating oil in a pinch. While chemically similar, diesel burns hotter and cleaner than standard heating oil. This can lead to increased wear and tear on a furnace's components over time.
Diesel and heating oil are nearly identical, except for the addition of dye in heating oil, which makes it exempt from road taxes. This is why diesel tends to be more expensive. Diesel also has a lower flashpoint than heating oil, making it easier to ignite.
If you are running low on heating oil, diesel can be purchased at a gas station and poured into your oil tank's fill pipe, which is usually located outside the house. It is important to wait around 15-20 minutes after pouring to allow any sediment to settle at the bottom of the tank.
While diesel can be used in a home oil furnace, it is not recommended for long-term use due to the increased wear on the furnace. It is a good temporary solution in an emergency, but it is better to plan ahead and ensure you do not run out of heating oil in the first place.

Diesel can be stored for six months
In an emergency, diesel fuel can be used as a substitute for home heating oil in your furnace. However, it is not recommended for long-term use as it burns hotter and cleaner than standard heating oil, which can lead to increased wear on your furnace's components.
If you are considering using diesel fuel in your home oil furnace, it is important to note that diesel fuel can be stored for up to six months without any additives. However, if you are planning to store diesel fuel, there are a few things you should keep in mind.
Firstly, diesel fuel should be stored in a well-sealed container to prevent air and water from getting in. Water can accumulate in the fuel over time, and if your engine is less than 20 years old, it may not be able to handle water in the fuel. Additionally, water can provide a breeding ground for microbes, which can destroy fuel quality.
Secondly, diesel fuel should be monitored and treated to prevent the growth of microbes. Biodiesel, in particular, increases the chances of microbial growth as microbes feed on it. Therefore, it is important to regularly remove water from your diesel fuel storage and treat it with fuel stabilizers to prevent microbial contamination.
By following these steps, you can safely store diesel fuel for up to six months and use it as an emergency substitute for home heating oil in your furnace. However, it is important to use diesel fuel sparingly in your furnace and only when necessary, as long-term use may void your warranty.

Diesel may void your furnace warranty
While diesel fuel can be used in a home oil furnace, it is important to note that doing so may void your furnace warranty. This is because diesel burns hotter and cleaner than standard heating oil, which can lead to increased wear and tear on your furnace's components over time. As a result, using diesel as a long-term fuel source for your home oil furnace could potentially damage the system, leading to costly repairs that would not be covered under warranty.
It is crucial to understand the terms and conditions of your warranty before making any modifications to your furnace, as different manufacturers have varying policies. Most manufacturers provide detailed information on their websites, including downloadable PDFs outlining the specific warranty terms and conditions. By familiarizing yourself with this information, you can make informed decisions about your furnace's fuel source while ensuring warranty coverage.
In some cases, warranties may be voided due to specific circumstances, such as relocating the furnace unit or using off-brand replacement parts. Additionally, certain actions, such as failing to perform annual tune-ups and regular maintenance, can also invalidate your warranty. Therefore, it is essential to carefully review the warranty requirements and maintain proper documentation of any maintenance or repairs performed by licensed professionals.
To avoid voiding your warranty, it is recommended to use the fuel type specified by the manufacturer. While diesel may be a suitable short-term substitute in emergencies, it is not advisable for long-term use due to the potential for increased wear and tear on your furnace. By following the manufacturer's guidelines and seeking professional assistance when needed, you can help ensure that your furnace remains under warranty protection.
Furthermore, it is worth noting that the cost of diesel, due to different taxation, tends to be higher than that of heating oil. While diesel may be a convenient option in emergencies, regularly using it as a substitute for heating oil can become expensive over time. Therefore, it is advisable to prioritize maintaining adequate levels of heating oil and only resort to diesel in urgent situations where your comfort and safety are at stake.
