Diesel Fuel Additives

AMSOIL Diesel Injector Clean (ADF) removes performance-robbing deposits from diesel fuel injectors to restore horsepower and improve fuel economy. It is formulated for all types of diesel engines, including high-pressure common-rail designs. Diesel Injector Clean is formulated to clean both the tough-to-remove internal diesel injector deposits surfacing in modern high-pressure common-rail diesel engines and traditional carbonaceous deposits. Unlike all-in-one fuel additives that may sacrifice performance in specific areas in the name of convenience, AMSOIL Diesel Injector Clean makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.

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.

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.

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.

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.

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.

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.

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.

The reduced sulfur levels in modern ultra-low-sulfur diesel fuel (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. For these reasons, many competitive claims are not based on ULSD fuels, rendering them inaccurate and irrelevant. 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.

Diesel applications operating in extremely cold environments face some unique challenges. As the temperature drops, 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 can eventually clog the fuel filter and starve the engine of fuel, preventing it from starting or even stalling out a running engine.

AMSOIL Diesel Recovery quickly dissolves gelled fuel to allow the operator to continue driving with minimal downtime. Diesel Recovery separates the molecular bonds of wax crystals that have agglomerated in diesel fuel. It thaws frozen fuel filters and reduces the need for a new filter, saving money and preventing an inconvenient trip to an auto parts store.

The marketplace offers many different diesel fuels, all with varying quality. AMSOIL Diesel Recovery performs well in most diesel fuels, including ULSD, off-road and biodiesel.

Over extended use, alcohol has a tendency to degrade components of some fuel delivery systems. AMSOIL Diesel Recovery contains no alcohol, making it safe for repeated treatments. In addition, Diesel Recovery is non-corrosive and contains no chemicals that interact with fuel system components. Corrosion can damage fuel system components and lead to prematurely-clogged fuel filters.

Diesel fuel quality varies from one filling station to the next, and low-quality fuel can have a cloud point as high as 40°F. A bottle of Diesel Recovery in the glove box is cheap insurance against being towed to a service station or getting stranded somewhere in subzero temperatures.

One 30oz. bottle of Diesel Recovery treats 30 gallons of fuel. When encountering a gelled fuel system, AMSOIL recommends taking the following steps for maximum effectiveness:

AMSOIL Diesel Cetane Boost (ACB) raises the cetane number of diesel fuel up to seven points for maximum horsepower, increased fuel economy and easier starts in all diesel engines. Diesel engines operate best on fuel with cetane values of 50 or higher. Most diesel fuel sold in North America has a cetane value of 40-45. Unlike all-in-one fuel additives that may sacrifice performance in specific areas in the name of convenience, AMSOIL Diesel Cetane Boost makes no sacrifices; it is purpose-built for diesel owners who demand maximum results.
