Diesel fuel is a type of fuel derived from crude oil, primarily used in diesel engines. It is denser and contains more energy per unit than gasoline, providing better fuel efficiency and higher torque. Diesel fuel is commonly used in trucks, buses, and industrial machinery, as well as in some passenger cars. It is typically classified into two types: diesel #1 (winter use) and diesel #2 (year-round use). Diesel fuel undergoes refining to meet environmental and performance standards.
When winter arrives, diesel engine owners face a common problem: fuel gelling. This happens when the paraffin wax in diesel fuel solidifies in cold temperatures, clogging fuel filters and lines.…
