Note 1) Diesel fuels are in USA broken up into 3 different classes: 1D, 2D and 4D. The difference between these classes depends on viscosity and boiling point ranges4D fuels tend to be used in low-speed engines. 2D fuels are used in warmer weather and are sometimes mixed with 1D  fuel to create a competent winter fuel.  1D fuel is preferred for cold weather as it has a lower viscosity. It used to be standard to see the fuel number on the pump, but a lot of gas stations do not state the fuel number anymore.

Note 2) European diesel standard from 2005

Note 3) Fuel oil is a kind of product with a lot of classes and under classes as well as varying specifications in different markets. The density ranges given represents the variation, however, some products may be outside these ranges.
