Diesel fuel, like diesel engines, is changing to meet
emission and other environmental requirements. The
Environmental Protection Agency (EPA) has introduced
major changes in diesel fuel for 2007, including Ultra
Low Sulfur Diesel fuel (ULSD), bringing the sulfur content
to 15 ppm, a staggering drop from the current
requirement of 500 ppm. Lower sulfur means lower
lubricity, the property that controls wear in the fuel
injectors and fuel pump.
New emission regulations have brought on engine
modifications such as exhaust gas recirculation (EGR),
causing rapid TBN depletion due to acid formation and
higher levels of soot loading in the oil. Higher soot and
particulate content has resulted in the introduction of
diesel particulate filters, but they clog easily, lowering
engine efficiency. All of these changes mean that new
diesel fuel needs quality fuel additives to keep equipment
operating efficiently and prevent malfunction. AMSOIL has made some changes to its line of fuel
additives. The changes
reflect the new diesel
fuel regulations and
incorporate the latest in
fuel additive technology.
AMSOIL Diesel Concentrate
AMSOIL Diesel Concentrate has
been reformulated with additional
lubricity properties. The new AMSOIL
Diesel Concentrate (ADF) is a total
system cleaner and lubricity improver
for all types of diesel engines.
AMSOIL Diesel Concentrate compensates
for the quality variances of
different fuels (including biodiesels)
and the deficiencies of today’s ULSD
for better engine operation.
Reduces Cylinder Wear,
Retains TBN Longer
New low-emission engine models
with high rates of exhaust gas recirculation
have inherent lubricant challenges.
These engines dump
excessive amounts of soot and acids
into the oil, accelerating wear on the cylinder walls.
Additionally, new engine oils meeting CJ-4 requirements
will have lower sulfated ash content, which controls
TBN levels. The new mandate only allows enough
sulfated ash content to reach a maximum TBN of 8-9,
making TBN retention even more important. New
AMSOIL Diesel Concentrate controls these issues by
neutralizing acids during combustion. This minimizes
acidic cylinder wear and reduces the rate of engine oil
TBN depletion, maintaining engine oil quality longer
for better protection.
Minimizes Soot Loading
AMSOIL Diesel Concentrate 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.
Fuel Stabilizer
Fuel degradation can cause gums, which increase
deposits and the chance of filter plugging. AMSOIL
Diesel Concentrate significantly improves the oxidation
and thermal stability of diesel fuel. It overcompensates
for ULSD fuel’s potential stability loss caused by
extra processing and sulfur removal. Diesel fuel treated
with AMSOIL Diesel Concentrate easily meets the
requirements of the National Council of Weights and
Measures (NCWM) Premium Diesel Fuel Specification
for resisting diesel fuel degradation.
Improves Fuel Economy and
Restores Horsepower
Diesel engines become less efficient over time. Fuel injector deposits
interrupt spray patterns, causing poor fuel atomization, incomplete
combustion, excessive emissions and smoke. Tests prove that AMSOIL
Diesel Concentrate cleans dirty injectors, not only improving fuel
economy by up to five percent, but also restoring horsepower to like
new. Acceleration is improved, and with regular use, AMSOIL Diesel
Concentrate continues to enhance performance by keeping injectors clean.
No-Cost Additive
High fuel prices are increasing operating costs for
everyone. AMSOIL Diesel Concentrate has proven in
industry standard tests to improve fuel economy in
used diesel engines by up to five percent. At $3.00 per
gallon for diesel fuel, even a modest three percent
improvement in fuel economy equals a savings of $0.09
per gallon. With a treat rate of one oz. of AMSOIL Diesel
Concentrate to five gallons of fuel, at U.S. Retail price
the net treat cost of AMSOIL ADF is $0.083 per gallon,
bringing the total savings to $0.007 per gallon
and negating the cost of AMSOIL Diesel Concentrate
altogether.
Improves Water Tolerance
AMSOIL Diesel Concentrate is an alcohol-free product
that protects fuel systems against water contamination.
It helps prevent fuel/water emulsions and it protects
metal against rust. Water can be drained easier and fuel
filters are less likely to plug, ensuring drivability.
AMSOIL Diesel Concentrate Replaces AMSOIL
Diesel Modifier
AMSOIL Diesel Modifier is discontinued, and
new AMSOIL Diesel Concentrate is applicable
in its place. There are no longer different fuel
additives for heavy- and light-duty diesel
engines, simplifying applications for customers. New AMSOIL Diesel
Concentrate meets and exceeds all catalytic
converter requirements.
AMSOIL Diesel Cold Flow Improver
Combining AMSOIL Diesel Concentrate with
a cold flow improvement property is not cost
effective in the summer months, or to
AMSOIL customers who live in the south. To
keep costs down for customers,
AMSOIL Diesel Concentrate no longer
includes a cold flow improver. Instead,
AMSOIL provides new AMSOIL Diesel Cold
Flow Improver (DFF) for low-temperature applications below 40°F.
Diesel fuel forms wax crystals and gels in cold temperatures,
plugging the fuel filter and affecting engine
operation. AMSOIL Diesel Cold Flow Improver for diesel
fuel is designed for use with ULSD and
conventional fuels. It functions by modifying the wax
crystal formation at low temperatures to depress the
pour point and improve the cold flow filtration properties.
AMSOIL Diesel Cold Flow Improver lowers the
cold filter plugging point by as much as 20°F and
decreases the need for #1 diesel fuel that is diluted with
kerosene. AMSOIL Diesel Cold Flow Improver contains
jet fuel-type deicer to help prevent ice formation in
fuels contaminated with water. It is recommended for
use with diesel engines and is compatible with diesel
exhaust particulate filters (DPFs). AMSOIL Diesel Cold
Flow Improver is excellent for use with AMSOIL Diesel
Concentrate and AMSOIL Cetane Boost Additive.
Recommended mix ratio is one oz. of additive per five
gallons of fuel.
Heating Oil Improver
AMSOIL Diesel Concentrate provides many of the same
benefits in heating oil furnace applications. For this
reason, Home Heating Fuel Extender (AHF) is discontinued.
AMSOIL Diesel Concentrate provides fuel oil
storage stability, water stability, rust protection, fuel
oil filter longevity, and its detergency
properties should help keep fuel oil nozzles clean for
proper spray in the combustion chamber. AMSOIL
Diesel Concentrate promotes trouble-free operation.
AMSOIL Diesel Cold Flow Improver is recommended
where fuel oil is stored outside.
Recommendations
AMSOIL Diesel Concentrate is recommended for use
with all types of heavy and light-duty, on or off-road and
marine diesel engines. The recommended mix ratio is
one oz. of additive per five gallons of fuel. It should be
used with every new tank of fuel for the best performance
and protection against fuel pump wear, injector
wear and injector deposits. It is compatible with all
types of exhaust emission systems such as diesel particulate
filters (DPFs). It is recommended that AMSOIL
Diesel Concentrate be added to fuel before storage.
Diesel Concentrate is excellent for use with AMSOIL
Cetane Boost and AMSOIL Diesel Cold Flow Improver.
Sweeping Changes
All AMSOIL fuel additive products will be sold in 16 oz.
bottles that have 22 ml. openings that fit directly into gas
tanks. The bottles are natural in color with graduations
on the label to ensure correct dosages. All products
have a new mix ratio of one oz. of additive to five gallons
of fuel (one bottle treats 80 gallons of fuel). AMSOIL
Diesel Concentrate and Diesel Cold Flow Improver are
now available in the new, more convenient bottle. |
