Biodiesel in your home heating oil works just like any other home heating oil — only better. It is completely compatible with all #2 oil furnaces. Biodiesel blends are actually better for your furnace, and reduce wear and tear on equipment components. That means they save you money on maintenance, repair and replacement over the long term.

Biodiesel has some solvent properties and will act as a solvent in the fuel. The solvent effect breaks down and cleans the old sludge and debris from the tank housing. The break-down of these deposits will pollute the fuel with particulate, which can cause fuel filters to plug rapidly. Once the pollutants are removed, this may take up to 3 filter changes, subsequent fuel filter service intervals should return to normal as continued use of the biodiesel keeps the system cleaner.

No matter what heating oil you use, it is highly recommended that you get your home heating system serviced once a year, to keep it running efficiently and avoid any need for costly repair.
