Diesel fuel is classified into several types based on its properties and intended use. The most common types include Diesel #1 (1-D) and Diesel #2 (2-D). Diesel #1 is a lighter fuel, often used in colder climates because it flows more easily at low temperatures. Diesel #2, on the other hand, is a heavier, more energy-dense fuel, commonly used in standard vehicles and heavy machinery. There are also specialized diesel fuels, such as biodiesel, which is made from renewable resources and offers a more environmentally friendly alternative to traditional diesel.
