Amsoil Diesel Concentrate plus Cold Flow Improver
Two fuel additives in one bottle adds convenience for diesel owners

Amsoil Diesel ConcentrateAMSOIL now offers a premium, year-round diesel fuel additive that provides improved efficiency and maximum cold-weather performance.AMSOIL Concentrate Plus Cold Flow Improver (DFC) combines the superior detergency of AMSOIL Diesel Concentrate (ADF)and the excellent anti-gelling properties of AMSOIL Cold Flow Improver (ACF) in one convenient package without sacrificing performance.
Improved Efficiency
AMSOIL Diesel Fuel Concentrate Plus Cold Flow Improver is formulated with excellent detergency properties to help keep injectors, rings,piston crowns and the fuel pump lubricated. By improving injector performance, combustion becomes more efficient and less soot is generated.Diesel Concentrate Plus Cold Flow Improver cleans dirty injectors, improving fuel economy by up to five percent and restoringhorsepower to like new. Acceleration is improved and with regular use, Diesel Concentrate Plus Cold Flow Improver continuesto enhance performance by keeping injectors clean. The net savings on fuel expense can result in no additional cost to vehicle operation.
Superior Cold-Weather Performance
As the temperature drops, the wax naturally found in diesel fuel begins to form crystals. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low quality fuels may form wax crystals in temperatures as warm as 40°F (4°C), most fuels have a cloud point near 32°F (0°C). The point at which the wax crystals clog the fuel filter is known as the cold filter-plugging point(CFPP). AMSOIL Diesel Concentrate Plus Cold Flow Improver lowers the CFPP by as much as 34°F (19°C) in ultra-low-sulfur diesel fuel (ULSD). It also reduces the pour-point temperature of treated diesel fuel, providing better fuel delivery to the injectors during cold weather. It is formulated with a jet-fuel type deicer that controls ice formation in all sections of the fuel system. Diesel Concentrate Plus Cold Flow Improver minimizes the need for the use of #1 diesel fuel, enabling better fuel economy, performance and lubricity. Product performance may vary depending on diesel grade and quality.

Pour Point Vs. CFPP
It is important to distinguish between CFPP and pour point. Many competitors make great claims regarding pour point, leading consumers to believe their products are superior when they actually have an inferior CFPP.Once fuel surpasses its cloud point, the wax crystals begin to clog the fuel filter. The CFPP temperature is a more important characteristic than pour point because the engine will not run if fuel cannot pass through the fuel filter.
Ultra-Low-Sulfur Diesel Fuel Challenges
The reduced sulfur levels in modern ULSD result in reduced lubricity, the property that controls wear in the fuel injectors and fuel pump. Improving lubricity in ULSD is difficult because it must be done without adding sulfur back into the fuel. Additionally, ULSD is subjected to extensive refining, making it even more difficult to treat. AMSOIL Diesel Concentrate Plus Cold Flow Improver is formulated specifically for modern ULSD fuel. Itimproves lubricity, helps maintain engine oil TBN and prevents soot loading. To learn more about
