Is it Safe to Replace Home Heating Oil With Diesel Fuel?

Home heating oil and diesel fuel are both fuel products made from the refining of crude oil. Chemically, the two fuels are very similar. Diesel is only slightly more viscous and contains several additives not usually found in home heating oil. This makes it a safe fuel to burn in a boiler or other heat-generating appliance, according to the website Inspectapedia.

It May Clog

Because diesel is slightly more viscous than home heating oil, it has a tendency to catch more easily. This means it may end up clogged in various parts of the furnace, including the fuel filter, the fuel lines or the jets.

Bottom Line

Diesel fuel can be used to replace home heating oil with no danger. However, the increased maintenance may make it more of a hassle. Also, it may not make economic sense, depending on the relative prices of the two fuels.
