Can you mix Kerosene and Heating Oil?

Updated: Mar 11


Fuel Oil



Have you ever wondered if you can mix Kerosene and Heating Oil(Fuel Oil)?? To answer this question, I did a little bit of research on defining characteristics of both. As you read below, you will see there are differences that will support our findings.



"Kerosene, also called paraffin or lamp oil, has a few defining characteristics. Its flashpoint is lower than home heating oil due to its higher viscosity and lower density. A flashpoint is the temperature at which a substance gives off flammable gasses that increase the risk of fire or explosion. Kerosene's flashpoint is around 100 degrees Fahrenheit, while home heating oil's flashpoint is around 140 degrees Fahrenheit.

Home heating oil, also called fuel oil, is less explosive than kerosene. Because of this, it is slightly safer for at-home use, and since it is readily available, it costs less money. It is safe to store, though you should be extra careful in low temperatures. Home heating oil can gel during the colder winter months, and it may not be the best option for homes with outdoor furnace fuel tanks.

However, kerosene does not gel during the cold winter months. In fact, people have used kerosene as an anti-gel agent in other oils, though most oil providers do not condone this. Both kinds are best used for heating systems in homes with great ventilation. "




So can you mix Kerosene and Fuel Oil?? The short answer is no, it would be too dangerous. Mixing the two could cause unsafe emissions, the potential for combustion, appliance damage, and unpredictable heat. Unsafe emissions could be toxic fumes released in your home which could lead to impacts on your health. The potential for combustion could lead to fire and explosions, very dangerous!!! Because Kerosene and Fuel Oil have different ignition temperatures and different outputs, the mixing could lead to unsafe heating environments in your home. So please take it from us, do not mix the two!! You should use compatible furnace systems and fuel types for the safest heating experience. If you are ever in doubt, please contact your local service provider!!
