AMSOIL DIESEL INJECTOR CLEAN FUEL ADDITIVE

AMSOIL Diesel Injector Clean is a concentrated, alcohol-free fuel additive that removes performance-robbing deposits from diesel fuel injectors, restores horsepower and improves fuel economy by up to 8%. It is formulated for all diesel engines, from Cummins-powered Ram 2500 and 3500 pickups to Ford 6.7L Power Stroke F-250s, Duramax-equipped Chevrolet and GMC trucks, and heavy-duty on- and off-road equipment.

Modern diesel fuel systems are working against you in ways that were not a factor ten years ago. High-pressure common-rail injectors operate at 30,000 psi and higher, with internal clearances as tight as 1 to 3 microns. Ultra-low-sulfur diesel fuel (ULSD) stripped out much of the natural lubricity that once protected fuel pumps and injectors. Meanwhile, the heat generated by these systems causes carbonaceous deposits to form inside injectors and on pintal nozzles, disrupting spray patterns and degrading combustion efficiency. The result is lost power, increased smoke, higher fuel consumption and premature filter plugging.

CLEANS BOTH INTERNAL AND EXTERNAL INJECTOR DEPOSITS
Traditional diesel fuel additives were designed to clean external deposits on conventional injector nozzles. They were not formulated to address the internal diesel injector deposits that form inside modern high-pressure common-rail systems. These internal deposits interfere with injector needle actuation and can lead to sticking or even seizure. AMSOIL Diesel Injector Clean uses advanced chemistry that targets both types of deposits, cleaning internal deposits on high-pressure common-rail injectors used in Ford 6.7L Power Stroke, Ram 6.7L Cummins and GM Duramax engines, as well as traditional carbonaceous buildup on older injector pintal nozzles. Clean injectors restore proper fuel atomization, which directly translates to recovered horsepower and torque.

IMPROVES FUEL ECONOMY UP TO 8 PERCENT
Dirty injectors produce poor fuel atomization, incomplete combustion and excessive emissions. When deposits disrupt spray patterns, unburned fuel goes out the exhaust as smoke instead of producing work. By restoring injectors to like-new condition, AMSOIL Diesel Injector Clean improves combustion efficiency and can improve diesel fuel economy by up to 8%. For trucks running 20,000 or more miles per year, the net savings on fuel can offset the cost of regular treatment entirely.

RESTORES LUBRICITY TO ULSD FUEL
The ASTM D975 diesel fuel standard specifies a maximum wear scar of 520 microns in ASTM D6079 testing. The Engine Manufacturers Association (EMA) sets a tighter limit of 460 microns. Testing of diesel fuels sampled across the United States revealed baseline wear scars ranging from 484 to 551 microns. After treatment with AMSOIL Diesel Injector Clean, those same fuels showed wear scars between 327 and 397 microns, well below both the ASTM and EMA limits. That level of lubricity improvement directly reduces wear on high-pressure fuel pumps and injectors in Bosch, Denso and Delphi common-rail systems, extending component service life and reducing maintenance costs.

MINIMIZES SOOT LOADING AND EXTENDS FILTER LIFE
Incomplete combustion generates excess soot that loads into the crankcase oil and plugs fuel filters. Modern diesel engines run hot, and the fuel returned to the tank carries enough heat to accelerate carbonaceous deposit formation in the fuel filter. AMSOIL Diesel Injector Clean cleans fuel injectors and piston rings for improved combustion and better sealing, which minimizes soot generation. Less soot means reduced soot-related wear, slower engine oil viscosity increase and longer intervals between fuel filter replacements. It also helps prolong the time between EGR and DPF regeneration events.

SEPARATES FUEL AND WATER TO PREVENT CORROSION
Many diesel fuel additives contain alcohol, which can emulsify water into the fuel and carry it through to the injectors, where it causes corrosion. AMSOIL Diesel Injector Clean is completely alcohol-free. It helps prevent fuel and water emulsions so that water-separating filters can safely remove water before it reaches the injectors. This protects the entire fuel system from corrosion-related damage.

COMPATIBILITY AND APPLICATIONS
AMSOIL Diesel Injector Clean is safe for use in all types of diesel fuel, including biodiesel. It is compatible with all exhaust emission systems, including diesel particulate filters (DPFs). Recommended for all heavy- and light-duty, on-road, off-road and marine diesel engines. It pairs well with AMSOIL Diesel Cetane Boost and AMSOIL Diesel Cold Flow for comprehensive fuel system treatment.
