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 soot loading 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. |
