What are Diesel Fuel Additives?
Diesel fuel additives are chemicals that are added to the diesel engine’s fuel to help improve several functions the engine has. There are many different kinds of additives and each delivers benefits that will improve your engine in many ways.

When the injectors are dirty, this affects the uniformity of the mist that is released. This will have effects on gas mileage, idle quality and the output of power to name a few things. Other benefits include the prevention of gelling in cold weather.
If the right additive is not present, diesel engines won’t start reliability when the temperature drops. Add in helping to deal with low fuel filterability, insufficient detergency, protecting fuel that has been standing for a long period of time, water contamination and more and you have a great product on your hands that will bring out the best in your diesel engine.
