Improves Fuel Economy and Restores Horsepower

Fuel injector deposits interrupt spray patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. High-pressure common-rail fuel systems are becoming commonplace as vehicle manufacturers attempt to produce more power while still meeting tightening emissions standards. In high-pressure common-rail systems, injection pressures near 30,000 psi atomize the fuel into a fine mist for more efficient combustion, yielding increased power and fuel economy while reducing emissions. To maintain these high pressures, injector assemblies are highly engineered, with clearances as tight as 1-3 microns (a human hair is typically 70-100 microns thick). Even minimal internal diesel injector deposits on the injector pintal or other components can lead to sticking and even seizure, reducing power, fuel economy and operability. Traditional additive chemistry is not designed to address these tough-to-remove deposits.

AMSOIL Diesel Injector Clean features advanced chemistry that delivers concentrated strength to target internal diesel injector deposits and traditional carbonaceous deposits, restoring horsepower and operability to like-new condition and improving fuel economy up to 4.5 percent. Acceleration is improved and, with regular use, AMSOIL Diesel Injector Clean continues to enhance performance by keeping injectors clean. The net savings on fuel can result in no additional cost of ownership.

Traditional Fuel Injector Pintal & High-Pressure Common-Rail Injector Pintal
Fuel injectors in high-pressure common-rail diesel engines use smaller, highly engineered components to produce the higher fuel pressures needed for improved combustion. The tighter clearances invite internal diesel injector deposits that interfere with injector needle actuation, reducing performance. External deposits can also form on the injector nozzle (the typical trouble spot for traditional injectors). While many other fuel additives have yet to catch up to the internal diesel injector deposit problem, AMSOIL Diesel Injector Clean targets deposits wherever they form, maximizing power, fuel economy and performance in high-pressure common-rail and traditional diesel engines.

Lubricates Fuel Pump and Injectors

Ultra-low-sulfur diesel fuel (ULSD) has significantly reduced lubricity - a critical property in controlling wear in fuel pumps and injectors. AMSOIL Diesel Injector Clean adds back the lubricity the fuel pump and injectors need, improving service life and saving time and money on maintenance costs.

  • Formulated for all diesel fuel systems, including highpressure common-rail designs
  • Cleans dirty injectors
  • Adds lubricity to reduce fuel-pump & injector wear
  • Improves fuel economy up to 4.5 percent
  • Improves power & torque

Reduces Cylinder Wear, Retains Engine Oil TBN Longer

With high rates of exhaust gas recirculation (EGR) in many diesel engines, acids from combustion are of particular concern. AMSOIL Diesel Concentrate 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 Injector Clean's powerful formula 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, reducing soot-related wear and motor 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 ultra low sulfur diesel 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 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.

Recommendation:
AMSOIL Diesel Injector Clean is recommended for use with all types of heavy- and light-duty, on- or off-road and marine diesel engines. For initial use, follow the Clean-Up recommendation; use Maintenance dose for regular treatment. Use with every tank of fuel for best performance and protection against fuel pump wear, injector wear and injector deposits. Compatible with all types of exhaust emission systems, including diesel particulate filters (DPFs). Add to fuel before storage. Excellent for use with AMSOIL Diesel Cetane Boost and AMSOIL Diesel Cold Flow. This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.

Heating Oil Improver
AMSOIL Diesel Concentrate provides many of the same benefits in heating oil furnace applications. It provides fuel oil storage stability, water stability, rust protection, fuel oil filter longevity, and in certain applications, can keep fuel oil nozzles clean for proper spray in the combustion chamber. AMSOIL Diesel Concentrate promotes trouble-free operation. AMSOIL Cold Flow Improver is recommended where fuel oil is stored outside.

Added rust protection is a bonus. Have you seen a fuel tank after 100,000 miles with improper warer seperation? It happens and we help you prevent the damage.

Special Question and answer section:

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 an 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 eight, 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.

 

1. Question:
AMSOIL Home Heating Fuel has been discontinued; can the new Diesel Concentrate be used in its place?
Answer:
Yes, AMSOIL Diesel Concentrate delivers fuel storage stability, rust protection, water separation, and its exceptional cleaning properties are expected to help keep fuel oil nozzles clean. AMSOIL Diesel Concentrate promotes trouble-free operation. AMSOIL Diesel Cold Flow Improver should be recommended when fuel oil is stored outside.

2. Question:
Does the new AMSOIL Diesel Concentrate meet the federal regulations for ultra low sulfur for diesel fuel?
Answer:
Yes, and the packaging label states so as regulated by law.

3. Question:
The old Diesel Concentrate worked well. Why did AMSOIL come out with a new Diesel Concentrate?
Answer:
The federal government mandated the use of ultra low sulfur diesel (ULSD) by June 2006 for the year 2007. ULSD contains <15 parts per million (ppm) sulfur where the previous content was <500 ppm sulfur. Sulfur acts as a lubricity agent that helps protect pumps and injectors from wear. As the sulfur content is lowered, so is the lubricity of the fuel. As a result of lower sulfur content, refiners or fuel distribution depots have been forced to add back some lubricity with the use of additives. This additive is expensive and is only blended in the fuel at the lowest additive concentration (LAC).
The fuel manufacturers have no incentive to add extra additive, which increases costs, so there is inherent risk of unnecessary wear on injectors and pumps. The new AMSOIL Diesel Concentrate Additive adds back all the lubricity and then some to properly protect diesel fuel components.

ULSD fuel has also shown to create more deposits within combustion chambers than previous diesel fuels. Deposits are detrimental to fuel economy, throttle response, and horsepower. AMSOIL Diesel Concentrate is a powerful detergent that cleans fuel system deposits and keeps the system clean with regular use. By cleaning deposits, AMSOIL Diesel Concentrate has shown to increase fuel mileage up to 5%. Consider that 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 only $0.083 per gallon, bringing the total savings to $0.007 per gallon and negating the cost of AMSOIL Diesel Concentrate altogether.
AMSOIL Diesel Concentrate is an alcohol-free product that also 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. In addition, 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. These are some key advantages of the new Diesel Concentrate among others identified on the data sheet (G-2236). Diesel equipment is expensive and owner/operators prefer to control the quality of the diesel fuel going into their engines rather than rely on the fuel producers. AMSOIL Diesel Concentrate provides outstanding performance in today’s ULSD fuel as well as the former 500 ppm version fuel and biodiesel. ULSD problems solved!

4. Question:
The claims state that the new Diesel Concentrate helps engine oil maintain TBN. How does it do this?
Answer:
TBN depletion is the result of combustion acids. AMSOIL Diesel Concentrate is designed to neutralize acids during combustion to prevent the acids from attacking the TBN reserve in the engine oil. Additionally, acids from combustion cause acidic cylinder wear. By neutralizing acids during combustion, AMSOIL Diesel Concentrate helps control acidic cylinder wear. These features are particularly important on exhaust gas recirculation (EGR) equipped engines (2002 and newer). By recirculating the exhaust back into the combustion chamber, more acids are introduced, wear increases, and TBN is rapidly depleted. For model year 2007 vehicles, the amount of EGR is being further increased compounding the problem.


Cetane Boost Diesel Fuel Additive

Amsoil Cetane BoostImproves combustion efficiency to increase power in diesel engines. Raises cetane three to seven numbers. Also improves low-temperature starting, fuel ignition quality and reliability. Treats up to 80 gallons. Product Code: ACB

Increases Cetane Number and Ignition Quality

Cetane number is the measure of a diesel fuel's ignition quality. Ignition quality is measured by ignition delay, the time between the start of fuel injection and the start of fuel combustion. Fuels with good ignition quality give short ignition delays and are assigned high cetane numbers.

Store Link for AMSOIL ACB

Data Sheet PDF for ACB (CETANE Boost Additive)

Cetane, the colorless, oily hydrocarbon on which the cetane number scale is based, has extremely good ignition quality and is assigned a cetane number of 100. The cetane numbers of North American diesel fuels may be as low as 37, which may cause startability and drivability problems.

AMSOIL Cetane Boost, ACB, increases a fuel's cetane number and improves its ignition quality. ACB encourages timely, uniform fuel ignition, discourages high pressure rate rise during the combustion cycle and solves startability and drivability problems associated with low cetane number diesel fuels.

FEATURES BENEFITS
Increases fuel economy up to 2%. Reduces operating costs.
Improves the spontaneous auto-ignition point of diesel fuel, which shortens ignition lag time. Diesel fuel ignites earlier in the cycle. More complete combustion for better performance, power and drivability.
Controls rapid pressure rise within the cylinder. Quieter, smoother operation.
Reduces cranking time to start. Extends battery and starter life.
Reduces white smoke, emissions and objectionable odors. Reduces environmental impact and makes diesel operation more pleasant.
Improves cold temperature starting. Better reliability and reduces maintenance costs.
Reduces misfiring during warm-up and at low temperatures. Saves on engine wear and tear. Helps prevent cracked pistons and rings.

 

Smoothes Operations
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.

Reduces Emissions
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.
Compatible with AMSOIL Diesel Fuel Additive Concentrate
ADC improves fuel efficiency, lengthens component life and aids cold temperature fuel flow. ACB contains no ethanol, methanol, MTBE or other alcohol.
Increase Performance, Profits

AMSOIL Diesel Fuel Additive Concentrate and AMSOIL Cetane Boost decrease expenses for fuel, injector cleanings and replacements. Even costly road service for cold temperature related failures.

ADC increases fuel economy and injector life, promotes reliable cold temperature operations and reduces emissions and black smoke. ACB increases cetane number and ignition quality for smooth, powerful operation, reliable cold starting and decreased emissions and white smoke.

Store Link for AMSOIL DFC

Data Sheet PDF for DFC (Diesel Concentrate w/ Cold Flow)

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.

1. Question:
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.

2.Question:
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.

3. Question:
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.

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.

4. Question:
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.

6. Question:
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.

7. Question:
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.

8. Question:
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.

9. Question:
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.

10. Question:
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.

11. Question:
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.

12. Question:
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.

14. Question:
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

15. Question:
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.

 


Improved Amsoil Cold Flow ImproverDiesel 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.

Store Link for AMSOIL ACF

Data Sheet PDF for ACF (Cold Flow - for Diesel Fuel)

PRODUCT DESCRIPTION
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.

Additional Benefits
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.

Application Information
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.
