AMSOIL Diesel Concentrate Plus
Cold Flow Improver (DFC) combines the superior
detergency of AMSOIL Diesel Concentrate (ADF) and
the excellent anti-gelling properties of AMSOIL Cold
Flow Improver (ACF) in one convenient package,
without sacrificing performance.
IMPROVES EFFICIENCY
AMSOIL Diesel Concentrate Plus Cold Flow Improver is
formulated with excellent detergency properties to
help keep injectors, rings and piston crowns
lubricated and free of soot. Diesel Concentrate Plus
Cold Flow Improver cleans dirty injectors, improving
fuel economy by up to five percent and restoring
horsepower to like new. Acceleration is improved and
with regular use, Diesel Concentrate Plus Cold Flow
Improver continues to enhance performance by keeping
injectors clean. The net savings on fuel expense can
result in no additional cost to vehicle operation.
ULTRA-LOW-SULFUR DIESEL
FUEL CHALLENGES
The reduced sulfur levels in modern ultra-low-sulfur
diesel fuel (ULSD) result in reduced lubricity, the
property that controls wear in the fuel injectors
and fuel pump. Improving lubricity in ULSD is
difficult because it must be done without adding
sulfur back into the fuel. Additionally, ULSD is
subjected to extensive refining, making it even more
difficult to treat. For these reasons, many
competitive claims are not based on ULSD fuels,
rendering them inaccurate and irrelevant. AMSOIL
Diesel Concentrate Plus Cold Flow Improver is
formulated specifically for modern ULSD fuel. It
improves lubricity, helps maintain engine oil TBN
and prevents soot loading.
REDUCES CYLINDER WEAR,
RETAINS ENGINE OIL TBN LONGER
With high rates of exhaust gas recirculation (EGR)
in modern diesel engines, acids from combustion are
of particular concern. AMSOIL Diesel Concentrate
Plus Cold Flow Improver neutralizes acids during
combustion. It helps reduce acid-caused cylinder
wear and helps extend engine oil TBN, maintaining
engine oil quality longer for better protection.
MINIMIZES SOOT LOADING
AMSOIL Diesel Concentrate Plus Cold Flow Improver is
a powerful cleaner that cleans fuel injectors and
piston rings for improved combustion and better
sealing. It minimizes soot generated from incomplete
combustion and helps keep soot out of the crankcase.
Reduced sootloading controls soot-related wear and
engine oil viscosity increase.
SUPERIOR COLD-WEATHER
PERFORMANCE
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 wax crystals clog the fuel filter is
known as the cold filter-plugging point (CFPP).
AMSOIL Diesel Concentrate Plus Cold Flow Improver
lowers the CFPP by as much as 34°F (19°C) in ULSD.
It also reduces the pour-point
temperature of treated diesel fuel, providing better
fuel delivery to the injectors during cold weather.
It is formulated with a jet-fuel-type deicer that
disperses water to control ice formation in all
sections of the fuel system. Diesel Concentrate Plus
Cold Flow Improver minimizes the need for the use of
#1 diesel fuel, enabling better fuel economy,
performance and lubricity.
POUR POINT VS. CFPP
It is important to distinguish between CFPP and pour
point. Many competitors make great claims regarding
pour point, leading consumers to believe their
products are superior when they actually have an
inferior CFPP. Once fuel surpasses its cloud point,
the wax crystals begin to clog the fuel filter. The
CFPP temperature is a more important characteristic
than pour point because the engine will not run if
fuel cannot pass through the fuel filter.
REDUCED NEED FOR #1 DIESEL
FUEL
One traditional solution to cold weather problems in
diesel engines is the use of #1 diesel fuel, which
is diesel fuel diluted with kerosene. While #1
diesel fuel has an advantage in low-temperature
operability, there are also several disadvantages.
The energy content of #1 diesel fuel is about 95
percent of 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
distributor, increasing the likelihood for wear on
these critical components. AMSOIL Diesel Concentrate
Plus 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.
RECOMMENDATIONS
One 16-oz. bottle of AMSOIL Diesel Concentrate Plus
Cold Flow Improver treats 40 gallons of fuel. Diesel
Concentrate Plus Cold Flow Improver will show no
signs of solidifying in its concentrated state in
the bottle until the temperature reaches -22°F
(-30°C). It will only freeze in its concentrated
state, and AMSOIL recommends storing it at
temperatures above 0°F (-18°C). If Diesel
Concentrate Plus Cold Flow Improver is allowed to
freeze in the bottle it can be thawed and used. When
mixed with diesel fuel, Diesel Concentrate Plus Cold
Flow Improver effectively improves diesel fuel
cold-temperature properties. It is important to
treat fuel before it has reached its cloud point as
Diesel Concentrate Plus Cold Flow Improver will not
dissolve wax crystals which have already formed in
the fuel.
AMSOIL Diesel Concentrate Plus
Cold Flow Improver meets federal regulations for
ULSD fuel. It complies with federal low-sulfur
content requirements for use in diesel motor
vehicles and non-road engines. While Diesel
Concentrate Plus Cold Flow Improver is formulated
specifically for ULSD fuel, it also performs well
with non-ULSD fuels, including biodiesel.
AMSOIL Diesel Concentrate Plus
Cold Flow Improver is specifically formulated to
improve the lubrication of fuel system components,
improve fuel flow, help maintain fuel integrity and
prevent the fuel filter and injectors from clogging.
Diesel Concentrate Plus Cold Flow Improver is
recommended for diesel-powered vehicles, home
heating oil and kerosene heating systems.
