Diesel Cold Flow

Combats Fuel Gelling in Cold Weather

Amsoil Diesel Cold Flow (ADD) combats diesel fuel gelling by improving diesel cold-flow ability. It is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures.

Diesel Cold Flow is formulated for a broad range of diesel fuels, including biodiesel and #1 and #2 ultra-low-sulfur diesel (ULSD). Diesel Cold Flow delivers confidence in your diesel’s performance. Its concentrated formula uses unique chemistry to target and eliminate specific performance issues, maximizing diesel power.

Reduces Need for #1 Diesel Fuel

Using #1 diesel fuel is one traditional solution to cold-weather diesel fuel problems. While #1 diesel fuel has an advantage in low-temperature operability, the energy content of #1 diesel fuel is about 95 percent that of #2 diesel fuel, resulting in reduced fuel economy and less horsepower, and it costs more at the pump. Diesel Cold Flow minimizes the need for blending standard #2 diesel fuel with #1 diesel fuel, helping to maintain fuel economy and keep engines functioning normally.

Helps Prevent Gelling

As the temperature drops, the wax naturally found in diesel fuel begins to crystallize. 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 40ºF (4ºC), most fuels have a cloud point near 32ºF (0ºC). The point at which the crystals clog the fuel filter is known as the cold filter-plugging point (CFPP). Diesel Cold Flow lowers the CFPP by up to 40ºF (22ºC) in ULSD.

Additional Benefits

Diesel Cold Flow uses a wax anti-settling component not found in other market-leading products. Wax anti-settling additives effectively modify wax crystals, drastically reducing their size. They resist settling and can pass through the filter more effectively, extending operability to a lower temperature.

Prevents Wax Settling

Wax crystals can settle and clog fuel filters (see picture). Amsoil Diesel Cold Flow is formulated with wax anti-settling additives that drastically reduce the size of wax crystals, preventing them from settling and allowing them to more effectively pass through the filter, improving low-temperature operability.

Diesel Cold Flow Benefits (ADD):

  • Lowers cold filter-plugging point (CFPP) by up to 40ºF
  • Enhances engine reliability in cold temperatures
  • Fights gelling in cold weather
  • Improves low-temperature startability
  • Prevents wax settling during storage
  • Inhibits fuel-filter icing
  • Safe for use in all diesel fuels, including biodiesel
  • Reduces downtime and maintenance costs
  • Alcohol-free

Applications

Diesel Cold Flow is specially formulated for improving the flow of diesel fuel, helping to maintain the integrity of fuel and prevent the clogging of filters and injectors. It is excellent for use with diesel fuels, heating oils and kerosene.

Recommendations

Add before filling tank. Diesel Cold Flow must be added at temperatures above the diesel fuel cloud point (the temperature at which wax begins to crystallize). It will not reverse gel or wax crystals once formed. Do not store at temperatures below 0ºF (-18ºC). Excellent for use with Amsoil Cetane Boost and Amsoil Diesel Injector Clean.
