Too long an ignition delay at high engine loads leads to an excessively rapid increase in pressure within the cylinder before combustion, which in turn, leads to diesel knock, or rough operation, especially on cold starts. Excessive pressure rise rates are theoretically caused by extra chemical reactions occurring before combustion. The products formed by the extra reactions burn rapidly. Rapid burning causes excessively rapid pressure rise in the cylinder. With a shorter ignition delay, the extra reactions don't have a chance to occur, hence the rate of pressure rise is reduced.
By reducing ignition delay, ACB maintains the proper cylinder pressure rise rate. Maintaining the proper pressure rise rate improves drivability. ACB also improves drivability by reducing throttling pintle nozzle coking. Throttling pintle nozzle coking produces noise and emissions. ACB cleans up coke deposits and prevents the formation of new deposits. ACB also reduces varnish formation.
ACB substantially reduces hydrocarbon and carbon monoxide emissions of heavy-duty on-road diesel trucks. By shortening the ignition delay, ACB helps fuel burn more completely, reducing carbon monoxide and hydrocarbon emissions. ACB may also reduce NOx and particulate emissions.
Available in Convenient Size
One 16-oz. can of ACB treats 100 to 200 gallons of diesel fuel and increases the fuel's cetane number three to seven points. Adding one can to 100 gallons of fuel provides maximum benefit.

The net savings on fuel expense can result in no additional cost to vehicle operation.
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 ultra-low-sulfur diesel fuel (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 controls 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. Product performance may vary depending on diesel grade and quality.
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.
Why did AMSOIL decide to reintroduce a combination Diesel Concentrate plus Cold Flow Improver (DFC) additive?
Answer: AMSOIL responded to the need for convenience by providing a product that combined the properties of the Diesel Fuel Concentrate and the Cold Flow Improver in a single package.
What function does AMSOIL Diesel Concentrate plus Cold Flow Improver perform?
Answer: This product combines all the benefits of both the AMSOIL Diesel Fuel Concentrate and the AMSOIL Cold Flow Improver. The diesel fuel concentrate portion of the product performs several important tasks, including keeping injectors, rings and piston crowns lubricated and free of soot buildup. It improves lubricity and minimizes wear throughout the fuel system. It also helps manage water, which enters fuel through condensation from the air inside fuel tanks and demulsifies fuel/water mixtures. The cold flow attributes reduce cold flow filter plugging point and diesel fuel pour point.
What are some key advantages for the AMSOIL Diesel Concentrate plus Cold Flow Improver?
Answer: a. Increases fuel economy up to 5%.
b. Restores horsepower and throttle response to “like new” performance.
c. Cleans injectors and combustion chambers.
d. Provides superior fuel flow to help prevent filter plugging in cold temperatures.
e. Reduces pour point of the fuel, making fuel flow to the engine easier.
f. Improves diesel engine reliability in cold temperatures.
g. Effective in a broad range of diesel fuels, including biodiesel and hard to treat USLD fuels.
h. Minimizes the need for blending standard #2 diesel fuel with lower quality #1 diesel fuel during cold temperatures.
i. Excellent for use with home heating oil and kerosene heat systems.
j. Aids in the retention of the engine oil’s total base number (TBN).
k. Extends fuel filter life.
What is Ultra Low Sulfur Diesel (USLD)?
Answer: USLD is fuel which has been hydro-treated at the refinery to reduce sulfur to no more than 0.0015% by weight (15 PPM). It is a legal specification mandated for environmental reasons and is required for all on-road diesel applications. It does, however, reduce the diesel fuel’s natural lubricating properties.
5. Question: Will DFC adequately treat federally regulated USLD?
Answer: Yes. AMSOIL Diesel Concentrate plus Cold Flow was specifically designed and tested with ultra low sulfur diesel fuels. This fuel is different than traditional diesel fuel in several ways and is more difficult to properly treat. AMSOIL Diesel Concentrate plus Cold Flow also treats traditional high sulfur content diesel fuel.
Does AMSOIL DFC improve engine performance?
Answer: By keeping injectors clean, AMSOIL Diesel Concentrate plus Cold Flow maintains the designed performance of the engine. If injectors become clogged, the spray pattern is affected and AMSOIL additives will clean the injectors to restore the original pattern and performance level.
What is the treat rate for Diesel Concentrate plus Cold Flow?
Answer: The treat rate is 2 ounces of additive per 5 gallons of fuel or one 16 ounce bottle to 40 gallons of fuel. The bottle is natural in color and is graduated for accurate dispensing to ensure proper mixing ratios.
What should be done to adjust for the cold temperatures during the winter months?
Answer: AMSOIL recommends purchasing diesel fuel that has been blended for winter use in that specific region, then adding AMSOIL Diesel Concentrate plus Cold Flow. This will ensure the engine or heating system will function on very cold days when needed most.
Should DFC be used in the diesel fuel to keep already gelled fuel from clogging the delivery system?
Answer: No. As temperatures drop, the wax, which is naturally found in the fuel, begins to form crystals. This is called the cloud point. These wax crystals will eventually clog the fuel filter and starve the engine of fuel or prevent it from starting. AMSOIL Diesel Concentrate plus Cold Flow must be added to the fuel before it gets cold enough for the wax crystals to begin forming. AMSOIL Diesel Concentrate plus Cold Flow will not dissolve wax or improve diesel fuel once wax crystals form. Low quality fuels may form wax crystals in temperatures as warm as 40°F. AMSOIL recommends Diesel Concentrate plus Cold Flow be added to fuel when temperatures approach 32°F, which is above the cloud point of most diesel fuel.
What type of performance can be expected from the new AMSOIL Diesel Concentrate plus Cold Flow?
Answer: AMSOIL Diesel Concentrate plus Cold Flow Improver inhibits wax crystal formation and can improve diesel fuel pour point. With the incorporation of DFC into ULSD, pour point decreased 31°F (17°C) and Cold Flow Filter Plugging Point (CFPP) was decreased by 36°F (20°C). Product performance depends on fuel type and quality.
Competitive products claim better cold temperature properties than AMSOIL DFC. Are these claims legitimate?
Answer: AMSOIL Diesel Concentrate plus Cold Flow was tested against a leading diesel fuel cold flow improver as part the development. The AMSOIL product outperformed competitive products particularly with B20 biodiesel and ULSD. Competitor claims can be misleading. It is important to distinguish between cold filter plugging point (CFPP) and pour point. Many competitive products make great pour point claims, leading consumers to believe their products are superior, when in reality the CFPP is inferior. The CFPP depression temperature is more important because fuel will not make it to the engine if the fuel filter is clogged.
What about using #1 diesel fuel instead?
Answer: AMSOIL Diesel Concentrate plus Cold Flow Improver minimizes the need for #1 diesel fuel in cold weather which reduces overall costs and lessens the impact from loss of lubricity with #1 diesel fuel. While #1 diesel fuel has an advantage in low temperature operability, there are several disadvantages as well. The energy content of #1 diesel fuel is about 95% that of #2 diesel fuel, resulting in reduced fuel economy and horsepower. #1 diesel fuel contains kerosene which provides less lubrication for the fuel pump and fuel distributor, increasing the chances of wear on these critical parts. In addition, #1 diesel fuel is more expensive.
Does AMSOIL DFC meet the federal regulations for ULSD fuel?
Answer: Yes. The statement found on the back label of AMSOIL DFC states, “This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.”
EPA regulation for diesel fuel additives went into effect on June 1, 2006. This regulation requires that all diesel fuel additives sold after June 1, 2006 with a sulfur content not exceeding 15 ppm sold in containers for use by the ultimate consumer must have the following statement:
“This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.'' For more information consult: http://www.aspalliance.org/dieselfuel/index.htm
Will using Diesel Concentrate plus Cold Flow void engine warranties?
Answer: The use of Diesel Concentrate plus Cold Flow will not void engine warranties and it is designed to help decrease engine fuel system wear from poor lubricity ULSD fuels.
Diesel Cold Flow Improver (ACF)
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 (ADF) no longer includes a cold flow improver. Instead, AMSOIL provides new AMSOIL Diesel Cold Flow Improver (ACF) for low-temperature applications below 40°. Designed for automotive, light truck, heavy duty and marine applications.
AMSOIL Cold Flow Improver (ACF) 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 distributor, 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 40ºF (4ºC), most fuels have a cloud point near 32ºF (0ºC). 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 34ºF (19ºC) in ULSD.
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 58ºF (32ºC), allowing fuel to flow to the engine more easily and improving diesel engine reliability in cold temperatures.
Concentrated ACF vs. ACF Blended with Fuel
AMSOIL Cold Flow Improver will not show any signs of solidifying until the temperature reaches -22ºF (-30ºC). Still, AMSOIL recommends storing Cold Flow Improver at temperatures above 0ºF (-18ºC). 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 ACF dissolves and effectively improves diesel fuel cold-temperature properties. Freezing will not harm ACF and it can be used after it is thawed.
AMSOIL Cold Flow Improver is specially formulated for improving the flow of 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 (715) 392-7101.
AMSOIL Diesel Recovery (DRC) is an emergency diesel
fuel treatment that quickly dissolves the wax crystals that form when diesel fuel has surpassed its cloud point. It liquefi es gelled diesel fuel and thaws frozen fuel fiters, avoiding costly towing charges and getting
diesel vehicles back on the road. Diesel fuel quality
varies from one fi lling station to the next, and lowquality fuel can have a cloud point as high as 4.4°C (40°F), making Diesel Recovery a necessity for
diesel operators in cold-weather climates.
