What You'll Learn
Diesel is a safe, temporary heating oil substitute
If you've run out of heating oil and need to get your furnace up and running, diesel is a safe, temporary substitute. Diesel is chemically similar to home heating oil and can be used to keep your furnace running in an emergency.
Before you switch to diesel, it's important to check your oil tank to ensure you actually need an alternative. The most common way to check the level of oil in your home oil system is to inspect the floating gauge. This gauge floats on the oil, indicating how full (or empty) your tank is. You can ensure your float works properly by removing its plastic covering and pushing it down with your hand. If your tank contains oil, the gauge will return to its original position at the proper oil level. If it doesn't, your tank has run out of oil. You can also manually check your tank's oil level using a yardstick. Place the yardstick down the fill tube of the tank to get a reading.
Once you're sure your tank is out of oil, you can begin using diesel as a heating oil alternative. Locate your oil tank's fill pipe and pour in your desired amount of diesel. A good rule is about 5-10 gallons for a day. Close your tank fill pipe and wait about 15-20 minutes to give the diesel time to settle and allow any sediments to sink back to the tank's base. Giving everything time to settle ensures sediment stays out of your fuel pipes and reduces the risk of blockages.
While diesel is a safe, temporary heating oil substitute, it's important to remember that it's not a long-term solution. Diesel burns hotter than standard heating oil, which can lead to increased wear on your furnace's components over time. It's also taxed differently, so it tends to be more expensive. Therefore, it's recommended to switch back to heating oil as soon as possible.

Diesel burns hotter than standard heating oil
Diesel fuel can be used as a substitute for standard heating oil in a home heating furnace. However, it should only be used as a short-term solution, as it burns hotter than standard heating oil. This additional heat can be beneficial for extremely cold nights, but over time, it can wear down the components of your furnace, shortening its lifespan.
Diesel burns slightly hotter than standard heating oil, which can lead to increased wear and tear on your furnace's components over time. This is because diesel has a higher flashpoint than heating oil, making it easier to ignite. As a result, it produces more heat without burning as much fuel. This makes diesel a good option for quickly heating your home, but it may not be the best choice for long-term use due to the potential for increased wear and tear on your furnace.
The difference in heat output between diesel and heating oil is relatively small. Common heating oils can produce 138,500 Btu (British Thermal Units) per gallon, while diesel typically produces around 137,500 Btu per gallon. This makes heating oil slightly more efficient than diesel, as it produces more heat with less fuel. However, it's important to note that the Btu of heating oil can vary depending on its type, and in some cases, it may have a lower Btu than diesel.
In addition to burning hotter, diesel also tends to be more expensive than heating oil. This is because diesel is taxed differently, as it has a road tax levied on it, while heating oil is untaxed and considered an essential fuel. The base cost of diesel is also typically higher than heating oil, and you will likely need to purchase it from a gas station, which can add to the expense. Therefore, it's important to consider the potential costs and benefits before choosing to use diesel as a substitute for heating oil in your furnace.

Diesel is more expensive than heating oil
While diesel can be used as an emergency substitute for heating oil in a furnace, it is not recommended for long-term use. This is because diesel is more expensive than heating oil.
Diesel and heating oil are both derived from crude oil and have similar boiling points. However, they are taxed differently. Heating oil is considered an essential fuel and is therefore untaxed. On the other hand, diesel has a road tax levied on it because it is primarily used for transportation. This makes the base cost of diesel higher than that of heating oil.
The price of both fuels fluctuates depending on supply and demand. The demand for heating oil increases during the winter, which can affect its availability and price.
Using diesel in a heating oil furnace as a short-term solution is possible, but it is important to follow the correct procedure. You should turn off the furnace and locate the oil tank's fill pipe before pouring in the desired amount of diesel, usually about 5-10 gallons per day. It is also important to use the correct yellow diesel containers to distinguish between the different fuels.
In summary, while diesel can be used as a temporary substitute for heating oil in a furnace, it is more expensive and should not be considered a long-term solution.

Diesel can be stored for six months
Diesel can be used as a substitute for heating oil in a fuel oil furnace. However, it is not a long-term solution as it burns hotter and cleaner than standard heating oil, which can lead to increased wear on your furnace's components. Diesel also costs more than heating oil due to the way it is taxed.
If you are using diesel as a substitute for heating oil, it is important to note that diesel can be stored for up to six months at a time before it degrades and is no longer safe to use. Additives can be used to extend the lifespan of diesel, but they have limitations and required treatments. Therefore, it is not advisable to store diesel for prolonged periods.
- Use biocides to prevent the growth of bacteria and fungus that can thrive in the water-diesel interface.
- Prevent or eliminate biofilm, a thick, sludge-like mass that can grow at the diesel-water interface.
- Use fuel treatment with demulsifying properties to separate water from fuel.
- Store diesel in an underground storage tank to keep it safer and cooler, and to extend its lifespan.
- Establish a monitoring and maintenance plan for your diesel storage system.
- Regularly remove water from your diesel storage and monitor it for microbes.
By following these tips, you can safely store diesel for up to six months and use it as a temporary substitute for heating oil in a fuel oil furnace.

How to check your oil tank levels
While diesel can be used as an alternative fuel for your furnace, it is not a long-term solution. Diesel burns hotter than standard heating oil, which can lead to increased wear on your furnace's components. It is also more expensive than heating oil. Therefore, it is essential to check your oil tank levels to ensure you are not using diesel unnecessarily. Here is a step-by-step guide on how to check your oil tank levels:
Step 1: Check your oil tank gauge
Most fuel oil tanks are equipped with a traditional float-style gauge. This gauge features an arm with a float attached to one end and a hinge. There is also a plastic vial with a disc that indicates the oil level in the tank. As the float lowers, the disc moves down accordingly. To read the level, look for the tick marks on the plastic vial. However, please note that the gauge may not always be accurate due to factors such as malfunction, oil buildup, or the shape of the tank.
Step 2: Manually check the oil level
If you want a more precise measurement, you can manually check the oil level using a yardstick or a gauge stick (also known as a "tank stick" or "dipstick"). First, locate the fill pipe or valve cap. Then, gently lower the yardstick or gauge stick into the tank until it touches the bottom. Bring it back up and read the depth of the oil. You can then compare this measurement to a tank chart to determine the exact amount of oil in your tank.
Step 3: Convert measurements and calculate remaining space
If your measurements are in inches, you will need to convert them to gallons using a fuel oil tank chart. Find your tank size on the chart and compare it to your inch measurement. To calculate the remaining space in your tank, subtract the total number of gallons from the tank's capacity.
Step 4: Consider a Smart Oil Gauge
For even more precise measurements, you may want to invest in a Smart Oil Gauge. This device can report your oil level to within a couple of gallons and can account for the geometry of your tank. It can also provide statistics on your oil usage over time, helping you adjust your thermostat accordingly.
Remember to check your oil tank levels regularly to ensure you don't run out of fuel unexpectedly. By following these steps, you can accurately determine your oil tank levels and make informed decisions about alternative fuel sources, such as diesel.
