Product Highlights View Full Description

Formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures. AMSOIL Cold Flow Improver is formulated for a broad range of diesel fuels, including #1 diesel, #2 diesel, biodiesel and ultra-low-sulfur diesel (ULSD).

AMSOIL Diesel Cold Flow (ACF) combats diesel fuel gelling by improving diesel cold-flow ability. It is formulated with an advanced deicer to enhance fuel flow and help prevent fuel filter plugging in cold temperatures. Diesel Cold Flow is formulated for a broad range of diesel fuels, including biodiesel and #1 and #2 ultra-low-sulfur diesel (ULSD). Unlike all-in-one fuel additives that may sacrifice performance in specific areas in the name of convenience, AMSOIL Diesel Cold Flow makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.

Reduces Need for #1 Diesel Fuel
Using #1 diesel fuel is one traditional solution to cold-weather diesel fuel problems. While #1 diesel fuel has an advantage in low-temperature operability, 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 injectors, increasing the likelihood for wear. AMSOIL Diesel Cold Flow 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.

Helps Prevent Gelling
As the temperature drops, the wax naturally found in diesel fuel begins to crystallize. 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 Diesel Cold Flow lowers the CFPP by up to 20ºF (15ºC) in ULSD.

Additional Benefits
AMSOIL Diesel Cold Flow 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 as much as 58ºF (32ºC), allowing fuel to flow to the engine more easily and improving diesel engine reliability in cold temperatures.

  • Disperses water to control ice formation & prevent gelling
  • Improves diesel cold flow ability by up to 20°F (15°C)
  • Enhances engine reliability in cold temperatures
  • Improves startability
  • Reduces downtime & maintenance costs

APPLICATIONS
AMSOIL Diesel Cold Flow is specially formulated for improving the flow of diesel fuel, helping to maintain the integrity of fuel and prevent the clogging of filters and injectors. It is excellent for use with diesel fuels, heating oils and kerosene.

RECOMMENDATIONS
Add before filling tank. AMSOIL Diesel Cold Flow must be added at temperatures above the diesel fuel cloud point (the temperature at which wax begins to crystallize). It will not reverse gel or wax crystals once formed. Do not store at temperatures below 0ºF (-18ºC). If product freezes, rewarm and shake thoroughly to restore normal functionality. Excellent for use with AMSOIL Cetane Boost and AMSOIL Diesel Injector Clean.

Vehicle: 2008 Ford F-250 XLT 4X4; 6.4L diesel. Work and play. 105k miles.
A new engine runs about $17K. I believe in ultimate lifespan (500K miles) and I use Amsoil products to achieve that goal. The Cetane Boost delivers both a smooth and more efficient power, plus improved mileage. Ford recommends No.1 diesel fuel, but that is not available where I live. Cetane Boost brings my engine to the performance level I did not receive factory new. Does it add to the cost of operation, yep, but you get what you pay for. Remember that $17K mentioned earlier? You can buy a lot of engine care for a fraction of a new engine.

It is very hard to pour fro the 64oz.bottle without spilling. I suggest a different style of bottle easier to pour without spilling.

Another Great Amsoil Product

By 

from Florida

Verified Buyer

Comments about Diesel Injector Clean:

The Diesel injector cleaner works well best I can tell. I have a Golf TDI 2012. I drive a lot. I have 78K miles as of this review. I use Amsoil Oil and change every 5K miles. I use the injector cleaner and so far I have not had one issue with the car. No joke 78K miles. It runs like when I bought it. The 0-60 time has not changed so I assume that the cleaner has kept my cars injectors clean. I am very please with Amsoil products.

Great Product

By 

from Alberta, Canada

Verified Buyer

Comments about Diesel Cetane Boost:

I am using this product in 2 older diesel engines, a 1984 Toyota Landcruiser 3B diesel with 520,000 km and a 1992 Dodge with a 5.9 ltr Cummins with 230,000 km. Mixing for a 7 point increase has given the Toyota a "seat of the pants" felt increase in power with overall fuel mileage up 1 mpg. The Dodge always had good power but with a 7 point increase mix I have gained a gear on hills and overall mileage is up 1.5 mpg. all while moving 5.5 tons of truck and load. Overall I am very satisfied with the product.

Ford did a lot of truck owners wrong.

By 

from Brandon, Fl.

Verified Buyer

Comments about Diesel Injector Clean:

I'll be brief. Injector Cleaner keeps my engine running smooth with excellent power delivery. A bigger plus is that my DPF cycles much less frequently meaning less wasted fuel and lessens the prospect of an expensive failure of theDPF. In conjunction with the Cetane Boost, Injector Cleaner should help me see my goal of 500k miles. You can pay for caring for your engine now or you can buy a new engine later. Oh, that'll be around $17k plus labor.

Cheap protection

By 

from NC

Verified Buyer

Comments about Diesel Injector Clean:

When I bought my 2015 duramax a good friend of mine recommended using the amsoil injector cleaner, he owns a welding company and regularly puts 75k each on his fleet of three trucks. We all know how expensive injector falior is. I have only put 28k on my truck so far and I expect to put another 300k without a single injector issue. I recommend using this cleaner/lubricant the day you buy your truck to protect and prevent buildup.
