All-season fuel additive
Equilon Lubricants has added a diesel fuel additive (DFA) to its line of Shell Rotella engine oil and lubricant products. The all-season DFA is designed to keep diesel engine injectors clean, prevent fuel gelling down to minus 40 deg. F, and help with cold-weather starts. In addition, it is said to reduce black smoke and soot, and disperse any water that gets into a truck's diesel fuel supply. According
