Product Details
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. New formula treats double the fuel.
Product Description
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.
- 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

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.

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.

Technical Information
Extra Information
Does AMSOIL Diesel Cold Flow work if diesel fuel is beginning to gel?
AMSOIL Diesel Cold Flow (ADD) is designed to prevent fuel from gelling and clogging fuel lines and filters. If the fuel is beginning to gel, the fuel should be treated with AMSOIL Diesel Recovery Emergency Fuel Treatment (DRC).<<< Link to our products detail page Diesel Recovery disperses the wax crystals and allows the fuel to flow.

30 gallons 
Can Diesel Cold Flow be mixed with other AMSOIL diesel fuel additives?
Yes. Diesel Cold Flow is fully compatible with Diesel Injector Clean (ADF) and Diesel Cetane Boost (ACB). Additionally, the Cold Flow found in Diesel All-In-One (ADB) is the same formula as Diesel Cold Flow
When should Diesel Cold Flow be used?
Diesel Cold Flow is a preventive product and should be used when ambient temperatures fall below 40 degrees F., as some fuels form wax crystals above freezing. Once wax crystals have formed, Diesel Cold Flow will not reverse the effects, so diesel fuel should always be treated at temperatures above which waxes form. 
If diesel fuel wax has already formed, operators should use AMSOIL Diesel Fuel Recovery (DRC) to dissolve waxes in the fuel filter, fuel lines and injectors.
How does Diesel Cold Flow work?
Waxes in diesel fuels are carried over in the refining process and solidify when temperatures fall during winter months. The waxes plug fuel filters and injectors, keeping fuel from reaching the engine. AMSOIL Diesel Cold Flow works by disrupting crystal formation of waxes keeping the wax small enough to flow through the fuel system to the engine. 
Can Diesel Cold Flow be used in home heating fuel?
Yes. AMSOIL Diesel Cold Flow is excellent for use with heating fuels, diesel fuels and kerosene.
Can Diesel Cold Flow be used in any diesel engine?
Yes. Diesel Cold Flow can be used in any diesel engine, and it is recommended for use in all types of heavy- and light-duty, on- and off-road and marine diesel engines.
If refiners make changes to diesel fuel in winter months, why do cold flow improvers need to be used?
During cold weather months, fuel refiners produce a #1 diesel fuel that flows more readily in colder temperatures. Some refiners also produce a product termed a winter blend which is a blend of #2, #1 and potentially cold flow improver additives. Fuel varies significantly in different regions, and refiners estimate how low the temperature will actually drop in these regions. Depending on the fuel source and temperature mix, fuel directly from gas stations may cause issues with wax formation, preventing vehicles from starting and stalling while on the road.
Can Diesel Cold Flow be used in any diesel engine?
Yes. Diesel Cold Flow can be used in any diesel engine, and it is recommended for use in all types of heavy- and light-duty, on- and off-road and marine diesel engines.
