Cleans and Protects
AMSOIL Diesel Injector Clean removes performance-robbing deposits from diesel fuel injectors to help 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.
Key Benefits
- Cleans dirty injectors
- Lubricates pumps and injectors to reduce wear
- Extends fuel-filter life
- Improves fuel economy up to 8%
- Restores power and torque
- Reduces smoke and emissions
- Helps prolong time between EGR and DPF regenerations
- Combats fuel-system corrosion
- Reduces downtime and maintenance costs
- Safe for use in all diesel fuels, including biodiesel
- Alcohol-free
Proven Performance
Helps Restore Horsepower & Improve Fuel Economy. Fuel injector deposits interrupt spray patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. In high-pressure common-rail systems, injection pressures can be 30,000 psi and higher, and injector clearances are as tight as 1-3 microns (a human hair is typically 70-100 microns thick). AMSOIL Diesel Injector Clean features advanced chemistry that targets internal diesel injector deposits and traditional carbonaceous deposits, helping restore horsepower and operability to like-new condition.
Lubricates Pumps & Injectors. Ultra-low-sulfur diesel fuel (ULSD) provides significantly reduced lubricity. AMSOIL Diesel Injector Clean adds back the lubricity the fuel pump and injectors need, reducing wear and improving service life.
Minimizes Soot-Loading. Diesel Injector Clean 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 engine oil viscosity increase.
Separates Fuel and Water. AMSOIL Diesel Injector Clean is an alcohol-free product that helps prevent fuel/water emulsions so that separating filters can safely remove water before it reaches the injectors, where it can cause corrosion.
Applications
Use AMSOIL Diesel Injector Clean in all types of heavy- and light-duty, on- or off-road and marine diesel engines. For initial use, follow the Clean-Up recommendation; use the 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.
