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.
Package sizes include:
16-oz. Bottle
5-Gallon Pail
55-Gallon Drum
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.
• Lowers cold filter-plugging point (CFPP) by up to 40°F
• 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
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.
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.
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 40°F (4°C), most fuels have a cloud point near 32°F (0°C). 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 40°F (22°C) in ULSD.
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.
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.
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 0°F (-18°C). Excellent for use with AMSOIL Cetane Boost and AMSOIL Diesel Injector Clean.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Diesel Cold Flow has kept our diesel fuel working great during the freezing temps that we have in Nevada. We use it in our tractors and everyday vehicles.

Cold weather keeps its hands off my diesel fuel
I add the proper amount to fuel tank capacity prior to filling up , so I get a good mixing action as diesel enters tank. No gelled diesel down to 5 degrees F.
