Running out of fuel in the middle of winter can be a nightmare, especially for those living in the Northeast or Connecticut, where cold winters are common. While the standard turnaround time for heating oil delivery is three business days, unpredictable weather and road conditions can sometimes delay deliveries. In such situations, diesel fuel can be used as a substitute for heating oil. Diesel and heating oil are similar substances, but diesel is taxed differently, making it more expensive. It also burns hotter than traditional heating oil, which can damage the heating system over time. However, adding 5-10 gallons of diesel fuel for a few days can help keep your home warm until your heating oil refill arrives.
| Characteristics | Values |
|---|---|
| Mixing diesel fuel with home heating oil | Possible |
| Heating oil delivery time | 3 business days, with same-day delivery in some cases |
| Diesel as an alternative | Temporary solution; taxed differently and more expensively than heating oil |
| Steps to add diesel to the heating oil tank | Turn off the system, add up to 10 gallons of diesel, wait for 5-10 minutes, reset the system |

What You'll Learn
Heating oil and diesel can be mixed without issues
Heating oil and diesel are similar substances and can be mixed without any issues. However, diesel is taxed differently and tends to be more expensive. It is best to use diesel only when you are out of heating oil or as a temporary solution.
Before filling your tank with diesel, it is important to verify that your tank is indeed low on fuel. This can be done by checking the floating gauge, which indicates how empty or full your tank is. If the tank is almost empty, it is good to have a bit of oil left to mix with the diesel. This is because a completely empty tank may require bleeding the lines to remove air and sludge from the nozzle, filter, and oil pump.
If you decide to use diesel, locate the fill pipe on the outside of your house and pour in the desired amount, typically 5 to 10 gallons. After adding the diesel, wait for about 5 to 10 minutes to allow any sediment to settle before restarting your heating system.
While diesel is a suitable alternative, it burns hotter than traditional heating fuel. Prolonged use can cause lasting damage to your heating system, which is not designed for higher temperatures. Therefore, it is recommended to limit diesel usage to a few days at a time and not as a long-term solution.

Diesel is a good alternative in emergencies
Diesel fuel can be used as an alternative to home heating oil in emergencies. It is a good option to keep your home warm when you cannot wait for a heating oil delivery. However, it is not a simple fill-and-go solution. Before filling your tank with diesel, you should first verify that you are out of heating oil. This can be done by checking the float gauge on the tank. If the tank is not empty, you can mix diesel with the leftover heating oil. This is better than running the tank completely empty.
If your tank is empty, you will need to remove air from the lines before adding diesel fuel. This process, known as bleeding the lines, can be messy and should be done by a professional. They can also remove any sludge from the nozzle, filter, and oil pump. After adding diesel to the tank, it is important to wait around 10 minutes for any impurities and sediment to settle before turning your heating system back on.
While diesel is a good short-term alternative to heating oil, it is taxed differently and tends to be more expensive. Diesel also burns hotter than traditional heating fuel, which can cause lasting damage to your heating system if used for extended periods. Therefore, it is recommended to use no more than 5-10 gallons of diesel per day for a few days at a time until you can get a refill of heating oil.

Diesel is taxed differently, making it more expensive
Diesel fuel can be used as an alternative to home heating oil. However, diesel is not a simple fill-and-go alternative. It is important to note that diesel is taxed differently from heating oil, making it more expensive.
Before filling your tank with diesel, it is recommended to verify that you actually require an alternative fuel source by checking your oil tank. This can be done by examining the floating oil tank gauge, which indicates the amount of fuel present. If your tank is not completely empty, mixing diesel with the leftover fuel is possible without any problems. However, if the tank is empty, you may need to conduct line bleeding to remove any sludge from the nozzle, filter, and oil pump.
Diesel should only be used as a temporary solution, as it burns hotter than traditional heating fuel. While this is not a major issue for short-term use, prolonged use can cause lasting damage to your heating system, which is not designed to withstand higher temperatures. To preserve your tank's longevity, it is recommended to limit diesel use to 5-10 gallons per day for a few days.
Additionally, consider the turnaround time for heating oil delivery, which is typically three business days, with some local companies offering same-day emergency deliveries. The need for diesel as an alternative may arise during unpredictable weather conditions or when waiting for a delivery is not feasible, especially if the safety and well-being of your family are at risk.

Diesel burns hotter and can damage systems over time
Diesel and heating oil are similar substances, and they can be mixed without any problems. However, diesel fuel burns hotter than heating oil and can damage systems over time.
The average diesel engine should run between 190 and 220 degrees Fahrenheit. It is not uncommon for heavy haulers to reach 230 degrees Fahrenheit in mountain grades, but anything over 220 degrees Fahrenheit can be a cause for concern. When the engine runs hotter than usual, the excess heat causes the gaskets and cylinder heads to expand where the fuel enters the combustion chamber. This leads to blown gaskets and warped cylinders, which can cause leaks and injection failure.
Once the engine oil reaches 240 degrees Fahrenheit, it will start to break down, damaging the oil system, including the high-pressure oil pump and fuel injectors. The hot oil can also damage the HPOP that sends oil to the injectors. Additionally, hot air from the engine can damage the turbocharger, weakening the spring and wastegate over time. This can result in reduced acceleration and the need to replace the turbo actuator.
To prevent damage to your system, it is important to regularly check the radiator hose to ensure coolant is running to and from the engine. Keep an eye out for leaks in the coolant tank and check your levels to ensure you are not running through more coolant than usual. A properly functioning engine should automatically reduce power when coolant runs low, but it is important to address this issue promptly to prevent further damage.

Diesel should only be used as a short-term solution
While diesel fuel can be used in home heating oil tanks, it should only be used as a short-term solution. Diesel and heating oil are similar substances, but diesel is taxed differently, making it more expensive. This higher cost means that diesel is not ideal for regular use.
Additionally, diesel burns hotter than traditional heating oil, which can cause lasting damage to a heating system if used for extended periods. Over time, the higher temperatures can damage a system not designed to withstand them. Therefore, it is recommended to limit diesel usage to 5-10 gallons per day for a few days at a time.
Another reason to use diesel sparingly is that it requires careful handling. When adding diesel to a heating oil tank, it is important to ensure that the tank is not completely empty, as this can cause issues with sludge in the oil pump, nozzle, and filter. Mixing diesel with leftover heating oil can help avoid these problems. However, even when mixed, diesel can still leave sediment that needs to settle before the system is restarted.
In summary, while diesel can be a useful short-term solution when heating oil is unavailable, it is more expensive, burns hotter, and requires careful handling. These factors make it less suitable for long-term use, and it is recommended to switch back to heating oil as soon as possible.
