It is important to note that these specifications can vary based on several factors, including the source of the crude oil, the refining process used, and the specific fuel type. It is also important to note that the specifications for HFO can change over time, as the refining process and regulations evolve.

Standard MDO

The specifications of Standard MDO may vary depending on the supplier and region, but in general, it typically contains:

• Pour Point: Typically, below -15℃

These specifications are subject to change, and it is always important to consult the product data sheet from the supplier for the exact specifications of the fuel you are using. It is also important to note that while standard MDO may meet the minimum fuel quality requirements set by international regulations, the fuel quality can vary depending on the refining process and the crude oil used to produce it.

• Sulfur Content: The most important specification for ULSD is its sulfur content, which is typically required to be less than 15 parts per million (ppm). This low sulfur content is what makes ULSD a cleaner-burning fuel compared to other diesel fuels with higher sulfur content.
• Density: ULSD is typically required to have a specific density, measured in kilograms per liter (kg/l) or pounds per gallon (lb/gal). The exact density requirement can vary depending on the location and regulations, but it is typically in the range of 0.820 kg/l to 0.865 kg/l (or 6.7 lb/gal to 7.2 lb/gal).
