According to the search results, the density of diesel varies depending on the type and temperature. The density of petroleum diesel is about 0.85 kg/l, which is equivalent to 850 kg/m3. However, diesel fuels are broken up into three different classes in the USA: 1D, 2D, and 4D, and the density of each class varies. For example, the density of 1D diesel is 875 kg/m3. The density of diesel fuel is also affected by temperature, and volume correction factors are used to adjust for temperature differences.
