About Diesel Fuel Additives
and its Importance
Diesel fuel is a highly complex fuel. It
changes chemical structure during the time after it leaves the
refinery to the time it is pumped into holding tanks and
into the fuel station to the time it gets pumped into your vehicle.
Fuel molecules oxidize and change structure and the energy per
unit volume of the fuel can change during this process which can
negatively affect the performance of your engine. By using the
proper type and ratio of fuel additives you can effectively combat
the effects of fuel degradation and increase the cetane value
of the fuel and allows the engine to extract more power from a
gallon of fuel, plus numerous other benefits.
Diesel fuel contains more energy per gallon
than gasoline. The three types of diesel fuel are 1D, 2D and a
blend of the two used during the winter. 1D is a lighter
grade of fuel and provides less energy than 2D. Generally 1D can
be used to reduce/eliminate fuel gelling in cold winter climates
or it can be mixed with 2D.
The ignition quality of diesel fuel is
measured by its cetane rating. The higher the cetane level the
easier the fuel burns evenly and the produces power. Average diesel
fuel is approximately a 40 cetane level. Large diesel trucks and
diesel pickup trucks such as the Powerstroke Diesel, Duramax
Diesel and Cummins Turbodiesel prefer a higher cetane rating in
the 45-50 range which is considered premium diesel. However, just
because a diesel fuel pump says "premium" on it does not necessarily
mean that the cetane level is between 45-50 since different states
have different regulations addressing what constitutes a premium
diesel fuel.
I recommend checking with the particular
fuel station as to exactly what cetane levels the fuel is they
are selling, or if you use the station regularly have the fuel
tested to be assured of quality fuel. Higher cetane numbers produce
improved driveability, reduced emissions and black smoke and the
driver of the vehicle can feel the power difference a quality
fuel with a high cetane number produces. This is why I recommend
AMSOIL Cetane Boost Additive to be used with each tank of fuel.
With the AMSOIL Cetane Boost you can be assured your fuel is of
the optimum cetane level for maximum performance regardless of
where you purchase your fuel.
The AMSOIL Cetane Boost
Additive
Increases the fuel cetane three to seven
numbers. Increased cetane restores power, reduces emissions and
noise and enhances cold starting. Improves combustion efficiency
to increase power in diesel engines and is alcohol-free for seal
and component compatibility. One 16 oz. can treats up to 200 gallons
of fuel and may be mixed with AMSOIL Diesel Fuel Additive Concentrate.
For Powerstrokes, Dodge Cummins and Duramaxes I recommend about
1/3 of a can of the AMSOIL Diesel Fuel Additive Concentrate and
AMSOIL Cetane Boost Additive per thankful. Store the opened bottles
in your truck in a 5 gallon pail with a snap lid in the bed of
your truck or back of your your truck so any leaks will not stink
up your truck.
I recommend the AMSOIL Cetane Boost Additive and the AMSOIL Diesel
Fuel Additive Concentrate instead of the Diesel Fuel Modifier
for Powerstrokes, Dodge Cummins and Duramaxes.
AMSOIL Diesel Fuel Additive Concentrate works to continuously clean the fuel system and provides the following
benefits:
A full spray pattern from clean injectors and efficient fuel
flow through clean passages can maximize power and fuel economy
and minimize emissions and smoke. It also lubricates injector
pumps which inhibits wear, which is a common problem with low
sulfur fuel.
Extends fuels cold temperature range. The inhibition of wax and
ice crystal formation allows fuel to flow at temperatures 20-35
deg. F lower than those at which it would flow untreated.
Stabilizes stored fuel: the inhibition of chemical reactions (such
as oxidation) during storage reduces the rate at which fuel degrades.
As fuel degrades it can form gums and sediments that can block
fuel lines and filters and lead to sludging and rusting.
Controls water contamination and rust: dispersants keep fine water
droplets suspended until they are vaporized during combustion.
Demulsifiers help separate larger columes of water for collection
by the water separator.
AMSOIL Diesel Fuel Additive Concentrate is alcohol-free for seal
and component compatibility. One 16 oz can treats up to 100 gallons
diesel fuel and it may be mixed with AMSOIL Cetane Boost Additive.
Diesel Fuels Changing
to Meet New Standards
Diesel engine technology is rapidly
evolving to meet new emissions standards set by the U.S. Environmental
Protection Agency that will go into effect in 2006. Substantial
reductions in particulate matter and nitrogen oxides are required
of newer engines, resulting in the use of exhaust aftertreatment
devices. These devices are easily poisoned by sulfur, so the pressure
is on to further reduce the level of sulfur in diesel fuels.
The EPA has proposed a cap of 15 parts per million (ppm) of sulfur
in diesel fuel beginning in 2006. Currently the level is 500 ppm.
This has led to a new class of ultra-low-sulfur diesel fuels (ULSD)
with levels of 50 ppm sulfur or lower.
New emission standards for heavy-duty truck and bus engines begin
with the model year 2004 and reflect the provisions of the Statement
of Principles (SOP) signed in 1995 by the EPA, The California
Air Resources Board (CARB) and the manufacturers of heavy-duty
diesel engines. The goal was to reduce nitrogen oxide (NOx) emission
levels from highway heavy-duty engines to approximately 2 grams
per brake horsepower per hour beginning in 2004.
Further, in May 2000, the EPA announced proposed emission standards
for model year 2007 and later heavy-duty highway engines to regulate
diesel fuel and to create emissions standards.
The ultra-low-sulfur diesel fuel has been proposed as a "technology
enabler" to pave the way for advanced, sulfur-intolerant exhaust
emission control technologies such as diesel particulate filters
and De-Nox catalysts, which will be necessary to meet the 2007
emission standards.
To get the ultra-low-sulfur levels, refiners perform additional
hydroprocessing and higher-severity hydrotreating. While these
processes reduce sulfur levels, they also affect other fuel properties.
These fuels lost the natural lubricity provided by some of the
polar compounds present naturally in the fuel. Low-lubricity fuels
can result in premature wear and failure of fuel system components.
Additionally, severely hydrotreated fuels can suffer from loss
of natural antioxidants that help prevent the fuel from forming
gums and sludges. A fuel's antioxidation properties are especially
important in today's fuel systems, where the fuel is exposed to
high temperatures. The ultra-low-sulfur fuels also can be more
corrosive than conventional fuels, requiring corrosion-inhibiting
additives. These fuels also can have very low electrical conductivity,
causing a safety concern with components such as high-velocity
pumps, where fuel can be exposed to significant static electrical
charges.
Because of these challenges, some new diesel fuel blending options
are being introduced. Gas to liquid (GTL) technology yields diesel
blend stocks from stranded gas reserves that might not otherwise
make it to market. GTL diesel fuels are desirable blending components
because they have the very low sulfur levels as well as high cetane
numbers.
A major percentage of all problems with diesel engines are related
to fuel quality, according to Wards Auto World, an e-magazine
that offers consumers free auto advice on the Internet.
Diesel fuel can vary from one shipment to another and from one
area to another. Changing vendors or changes suppliers sometimes
make to the fuel they sell also bring different qualities of diesel
fuel to the market.
Three important components that vary the most in diesel fuel are
cetane, weight and viscosity.
Cetane defines the susceptibility of the fuel to self-ignite.
Acceptable cetane levels are between 40 and 45, but few fuel distributors
advertise this since each batch may be different. Cetane influences
both starting and combustion roughness on an engine. High altitudes
and low temperatures call for a greater cetane number of the fuel.
The weight of the fuel of its gravity plays a role in the heat
content of the fuel. Number one is a "lighter" grade and number
two is "heavier," or weighs more per gallon. Number one provides
better starting in cold temperatures, but number two has better
lubricating qualities and contains more heat units (BTUs) per
volume.
The number one fuel is less dense so it becomes thinner when heated
than the number two fuel. As the fuel temperature continues to
rise, fuel begins to leak through the high-pressure parts of the
injection pump causing it to pump less fuel, and that leakage
results in a power loss of between one percent and seven percent.
Diesel fuel treatments increase fuel quality and extend the lives
of engines. The only way to be sure of fuel quality is to treat
it with fuel additives.
