PRODUCT DESCRIPTION
AMSOIL Cold Flow Improver is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter
plugging in cold temperatures. It is formulated for a broad range of diesel fuels, including #1 diesel, #2 diesel,
biodiesel and ultra-low-sulfur diesel (ULSD).
Reduces Need for #1 Diesel Fuel
One traditional solution to cold weather problems in diesel fuel is using #1 diesel fuel, which is diluted with
kerosene. While #1 diesel fuel has an advantage in low-temperature operability, it has several disadvantages. 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 on these critical components. AMSOIL Cold Flow Improver
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.
Superior Cold Filter Plugging Point Depression
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 crystals clog the fuel filter is known
as the cold filter-plugging point (CFPP). AMSOIL Cold Flow Improver lowers the CFPP by as much as 34°F (19°C) in
ULSD.
Additional Benefits
AMSOIL Cold Flow Improver 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 by as much as 58°F (32°C),
allowing fuel to flow to the engine more easily and improving diesel engine reliability in cold temperatures.
Does Not Freeze When Blended With Fuel
AMSOIL Cold Flow Improver will not show any signs of solidifying until the temperature reaches -22°F (-30°C).
Still, AMSOIL recommends storing Cold Flow Improver at temperatures above 0°F (-18°C). AMSOIL Cold Flow Improver
will only freeze in its concentrated state, not when it is mixed with fuel. It is designed to be mixed with diesel
fuel, at which point it dissolves and effectively improves diesel fuel cold-temperature properties. Freezing will
not harm Cold Flow Improver and it can be used after it is thawed.
Applications
AMSOIL Cold Flow Improver is specially formulated for improving the flow of diesel fuel, helping to maintain the
integrity of fuel and preventing the clogging of filters and injectors. It is excellent for use with diesel fuels,
heating oils and kerosene. Two oz. of AMSOIL Cold Flow Improver treats five gallons of fuel, or one 16 oz. bottle
for 40 gallons. The clear bottles feature an easy-to-read graduation label for accurate dispensing, helping to
ensure proper treat ratios.
DANGER: COMBUSTIBLE. HARMFUL OR FATAL IF SWALLOWED. HARMFUL IF INHALED OR
ABSORBED THROUGH SKIN. EYE AND SKIN IRRITANT. KEEP OUT OF REACH OF CHILDREN. Carefully read precautions on label of
AMSOIL Cold Flow Improver container before use. A Material Safety Data Sheet (MSDS) is available online at www.amsoil.com or upon request at
