AMSOIL Diesel Cold Flow (ACF) 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). Unlike
all-in-one fuel additives that may sacrifice performance in specific areas
in the name of convenience, AMSOIL Diesel Cold Flow makes no
sacrifices; it is purpose-built for diesel owners who demand maximum
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. In addition, the kerosene used in #1 diesel fuel
provides less lubrication for the fuel pump and fuel injectors, increasing the likelihood
for wear. AMSOIL Diesel Cold Flow minimizes the need for blending standard #2
diesel fuel with lower-quality #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). AMSOIL Diesel Cold Flow
lowers the CFPP by up to 20ºF (15ºC) in ULSD.
AMSOIL Diesel Cold Flow uses a jet-fuel-type deicer that disperses water to control ice
formation throughout the fuel system. It inhibits wax crystal formation and can improve
diesel pour point as much as 58ºF (32ºC), allowing fuel to flow to the engine more
easily and improving diesel engine reliability in cold temperatures.
- Disperses water to control ice
formation & prevent gelling
- Improves diesel cold flow ability by
up to 20°F (15°C)
- Enhances engine reliability in cold temperatures
- Improves startability
- Reduces downtime & maintenance
AMSOIL 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. AMSOIL 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). If product freezes, rewarm
and shake thoroughly to restore normal functionality. Excellent
for use with AMSOIL Cetane Boost and AMSOIL Diesel
