Modern, compact and sophisticated engines are especially sensitive to certain problems such as fouling, which reduces engine performance and longevity, increases fuel consumption and the emission of carbon dioxide and pollutants. High-quality fuels with additives are probably the most effective in countering the negative effects of fouling, thanks in particular to the detergent additives they contain . A premium fuel with additives can be used for both curative and preventive purposes.
Diesel fuel attracts moisture, which is bad news not just for an engine's operation, but also introduces the potential for corrosion inside the fuel system. To assist the mechanical water separator installed on almost every diesel engine, it's possible to use additives that reduce the risk presented by moisture.Some diesel additives combine lubrication and detergents in order to remove engine deposits, while making up for ultra-low sulfur or biodiesel's lack of lube.
Diesel stabilizers work to curb any algae growth in the fuel, as well as prevent sludge from forming in the tank. It further helps fight against gelling when stored at low temperatures.One of the most common diesel additives in some regions that deal with
cold winter weather is anti-gel treatment. Due to the presence of paraffin in diesel fuel, the fuel has a tendency to get cloudy and eventually solidify into a gel at lower temperatures. Biodiesel also has this issue
