Can You Put Diesel In An Oil Furnace?

Can You Put Diesel In An Oil Furnace?

As winter approaches, many homeowners turn to kerosene furnaces for heating. But what if the oil runs out and you cannot fill the furnace as planned? Can you use diesel as a temporary alternative? We have researched, and here is the answer.

Diesel is available at gas stations and can be used in place of fuel oil in almost any furnace. Diesel and #2 kerosene are both medium-heavy petroleum distillates that produce approximately the same amount of heat and can be burned in the same system. Because of this, diesel can be used as first aid in an emergency.

The potential use of kerosene furnaces and diesel fuel requires further consideration. Continue reading to learn why this fuel may be beneficial to you.

Is diesel fuel the same as kerosene?

As diesel oil burns similarly to the oil used to heat your home, it is acceptable as a temporary fill in your kerosene furnace. It is critical to recognize this.

Diesel is not a permanent substitute for kerosene in heating systems. The continued use of the furnace will eventually compromise its functionality. Diesel burns slightly hotter than fuel oil and will ultimately damage furnace components.

Recognize that diesel should only be used as a last resort. It should be noted that diesel is only an acceptable substitute for #2 kerosene. #2 refers to the weight and grade of oil, and this grade of fuel oil is used in almost all fuel oil furnaces.

If you’re using a different grade of oil in your heater, diesel is unlikely to work. Please ensure that the oil type used in your furnace is No. 2 kerosene.

Can I run my kerosene furnace on off-road diesel?

Off-road diesel is red, indicating that it is tax-free and suitable for use as off-road fuel. Examples include construction fuels, equipment never used on public roads, agricultural services, and kerosene boiler fuels. Can you, however, use these types of diesel fuel in your home furnace to heat it?

In general, the answer is yes. Tinted off-road diesel is a viable substitute for fuel oil. Today, most colored and off-road diesel is ultra-low sulfur diesel.

The EPA and most state laws classify kerosene as low, medium, or high sulfur. This means that while some fuel oils cannot be colored diesel (if used for off-road equipment or agricultural applications), colored diesel or off-road diesel can.

What factors influence the price of kerosene and diesel?

You might notice a difference if you buy diesel and kerosene in exact amounts. This is true even if the state taxes diesel but not heating oil. The price of crude oil at any given time is the primary determinant of both fuel costs.

In many ways, kerosene and diesel fuel are similar fuels. The fact that the prices are the same demonstrates this. However, each of these fuels has an inherent cost that sometimes makes one more expensive than the other.

Diesel is produced to meet stringent sulfur standards that fuel oil does not have to meet, which drives its price. Some taxes are expressly imposed. Kerosene, unlike diesel, has to bear the costs of transportation. You can get the diesel at your local gas station, but you’ll need to have the fuel oil delivered.

To add to the cost, trucks transporting fuel oil are much smaller than diesel trucks. This means that less fuel will be delivered per truck. All of these factors are reflected in the price of oil.

While the products are very similar, differences in handling affect the price. Diesel may appear a low-cost alternative but remember that it will cause damage and be costly to repair later.

Five gallons of diesel will last how long in an oil tank?

Furthermore, 5-10 gallons of diesel or kerosene will last approximately 1-2 days. Keep this in mind as you decide how much diesel to buy between now and your next kerosene delivery.

Consider adding more fuel to your 10-gallon diesel fuel if you have a larger home. This will keep your home warm until your next delivery arrives.

Advice on using other fuels in your home furnace

In the short term, diesel is an acceptable alternative to kerosene. However, it is not gasoline. Gasoline is easily distilled and, if placed on the furnace, can cause damage and other operational issues. Under no circumstances should you run your furnace on gas for an extended period.

Please keep the following in mind if you store diesel fuel at home for heating purposes:

Fuel should be stored in yellow containers that are clearly labeled.

Diesel should not be stored for more than six months because it will degrade and become potentially dangerous. Diesel can have additives added to it to extend its shelf life.

Within one year, treated fuel must be used or disposed of. Finally, diesel furnace oil can only be replaced in one direction. This means that vehicles cannot use heating oil instead of diesel fuel. It lacks the lubrication required to keep the engine running correctly without causing damage or being potentially dangerous.

Know If An Oil Furnace Run On Diesal!

Diesel is accepted as a first-aid solution when you run out of kerosene to keep your home comfortable and warm. Understanding its limitations and what it can do could be an excellent temporary solution to a bad situation. We hope this guide has helped you better understand what Diesel can do for you as an Oil Heater user.
