Diesel Plus diesel fuel conditioner is a multipurpose fuel additive that will solve year-round problems associated with diesel fuel systems. Its L-10 Superior Detergency rating cleans fuel system components, keeping diesel engines running smoothly and at peak efficiency. Diesel Plus replaces the necessary lubrication for fuel system components that is lost with the use of ultra-low sulfur diesel fuel (ULSD). ULSD is also less stable than low sulfur diesel fuel (LSD). Diesel Plus contains anti-oxidants to improve the stability and lengthen the storage life of ULSD. Its moisture-scavenging properties help remove moisture and aids in preventing bacteria from growing in the fuel. When used at the winter treat rate, Diesel Plus has the ability to lower the fuel’s cold filter plugging point (CFPP) as much as 22°F, providing quick cold-weather starts along with improved combustion.
