Stove Oil and kerosene are different specifications of heating fuels and both are typically low-sulfur fuels. Low-sulfur fuels have below 500 parts per million of sulfur. While “ultra-low sulfur” fuels are under 15 parts per million. We aspire to use ultra-low sulfur fuels, however, kerosene often is only available as a low-sulfur formulation. If available we will use ultra-low sulfur kerosene, but cannot guarantee its supply. Our stove oil and kerosene products are essentially the same product.
The big difference between kerosene and #1 stove oil is the ASTM Specifications for use. Kerosene’s ASTM specification requires an ability to be taken up by a wick, like in a wick heater. Stove oil does not require this property but can still work in a wick heater. Both specifications are #1 diesel fuel, on-road #2 diesel fuel having a slightly heavier specific gravity. These names and product differences can be confusing, so we welcome our customers to call us to ensure you’re getting the right product.
