Two Additives in One

New Diesel Concentrate Plus Cold Flow Improver (DFC) provides

top performance and convenience.

AMSOIL now offers a premium, year-round diesel fuel additive that provides improved

efficiency and maximum cold-weather performance. AMSOIL Diesel Concentrate Plus

Cold Flow Improver (DFC) combines the superior detergency of AMSOIL Diesel

Concentrate (ADF) and the excellent anti-gelling properties of AMSOIL Cold Flow

Improver (ACF) in one convenient package without sacrificing performance.

Improved Efficiency

AMSOIL Diesel Concentrate Plus Cold Flow Improver is formulated with excellent

detergency properties to help keep injectors, rings, piston crowns and the fuel pump

lubricated. By improving injector performance, combustion becomes more efficient and

less soot is generated. Diesel Concentrate Plus Cold Flow Improver cleans dirty injectors,

improving fuel economy by up to five percent and restoring horsepower to like new.

Acceleration is improved and with regular use, Diesel Concentrate Plus Cold Flow

Improver continues to enhance performance by keeping injectors clean. 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.

Ultra-Low-Sulfur Diesel Fuel Challenges

The reduced sulfur levels in modern ULSD result in reduced

lubricity, the property that controls wear in the fuel injectors and

fuel pump. Improving lubricity in ULSD is difficult because it

must be done without adding sulfur back into the fuel.

Additionally, ULSD is subjected to extensive refining, making it

even more difficult to treat. AMSOIL Diesel Concentrate Plus

Cold Flow Improver is formulated specifically for modern ULSD

fuel. It improves lubricity, helps maintain engine oil TBN and

prevents soot loading.

Recommendations

One 16-oz. bottle of Diesel Concentrate Plus Cold Flow Improver

treats 40 gallons of fuel. Diesel Concentrate Plus Cold Flow

Improver will show no signs of solidifying in its concentrated

state in the bottle until the temperature reaches -22°F (-30°C). It

will only freeze in its concentrated state, and AMSOIL recommends

storing it at temperatures above 0°F (-18°C). If Diesel

Concentrate Plus Cold Flow Improver is allowed to freeze in the

bottle it can be thawed and used. When mixed with diesel fuel,

Diesel Concentrate Plus Cold Flow Improver effectively

improves diesel fuel cold-temperature properties.



Because DieselConcentrate Plus Cold Flow Improver will not dissolve wax crystals

which have already formed in the fuel, it is recommended that

fuel already in the tank be treated at temperatures above 32°F

(0°C). When filling the tank with fuel from an underground tank,

it may be treated with Diesel Concentrate Plus Cold Flow

Improver when temperature is below 32°F (0°C) because the fuel

itself is warmer.



AMSOIL Diesel Concentrate Plus Cold Flow Improver meets

federal regulations for ULSD fuel. It complies with federal lowsulfur

content requirements for use in diesel motor vehicles and

non-road engines. While Diesel Concentrate Plus Cold Flow

Improver is formulated specifically for ULSD fuel, it is also

effective with non-ULSD fuels, including biodiesel.

AMSOIL Diesel Concentrate Plus Cold Flow Improver is specifically

formulated to improve the lubrication of fuel system components,

improve fuel flow, help maintain fuel integrity and prevent

the fuel filter and injectors from clogging. Diesel

Concentrate Plus Cold Flow Improver is recommended for dieselpowered

vehicles, home heating oil and kerosene heating systems.
