Product Description
AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency. It compensates for the variances in
quality of different fuels (including biodiesel) and the deficiencies of today’s ultra-low-sulfur diesel fuel
(ULSD) for better engine operation. New engine technology, tighter tolerances and emission regulations require
high-quality diesel fuel for long-term engine operability. AMSOIL Diesel Concentrate meets the low-sulfur mandate
and improves diesel fuel quality to exceed today’s stringent performance requirements. AMSOIL Diesel Concentrate
extends equipment life, lowers operating costs and improves diesel performance.
Improves Fuel Economy and Restores Horsepower
As diesel engines are used, they become less efficient over time. Fuel injector deposits interrupt spray patterns,
causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. Tests prove that AMSOIL Diesel
Concentrate cleans dirty injectors, improving fuel economy by up to 5 percent and restoring horsepower to like-new
condition. Acceleration is improved and with regular use, AMSOIL Diesel Concentrate continues to enhance
performance by keeping injectors clean. The net savings on fuel expense can result in no additional cost to vehicle
operation.
Lubricates Fuel Pump and Injectors
Ultra low sulfur diesel fuel has significantly reduced lubricity – a critical property in controlling wear in fuel
pumps and injectors. AMSOIL Diesel Concentrate adds back all the lubricity properties needed and more. Fuel pump
and injector service life is extended, saving time and money on maintenance costs.
Reduces Cylinder Wear, Retains Engine Oil TBN Longer
With high rates of exhaust gas recirculation (EGR) in modern diesel engines, acids from combustion are of
particular concern. AMSOIL Diesel Concentrate neutralizes acids during combustion. It helps reduce acid-caused
cylinder wear and helps extend engine oil TBN, maintaining engine oil quality longer for better protection.
Minimizes Soot Loading
AMSOIL Diesel Concentrate is a powerful cleaner that 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, resulting in reduced soot-related wear and engine oil viscosity increase.
Fuel Stabilizer
Fuel degradation can cause gums, which increase deposits and the chance of filter plugging. AMSOIL Diesel
Concentrate significantly improves the oxidation and thermal stability of diesel fuel. It overcompensates for
ultra-low-sulfur diesel fuel’s potential stability loss caused by extra processing and sulfur removal. Diesel fuel
treated with AMSOIL Diesel Concentrate easily meets the requirements of the National Council of Weights and
Measures (NCWM) Premium Diesel Fuel Specification for resisting diesel fuel degradation.
Separates Fuel and Water
AMSOIL Diesel Concentrate is an alcohol-free product that protects fuel systems against water contamination. It
helps prevent fuel/water emulsions and it protects metal against rust. Water can be drained easier and fuel filters
are less likely to plug, ensuring drivability.
Heating Oil Improver
AMSOIL Diesel Concentrate provides many of the same benefits in heating oil furnace applications. It provides fuel
oil storage stability, water stability, rust protection, fuel oil filter longevity, and its exceptional cleaning
properties are expected to keep fuel oil nozzles clean for proper spray in the combustion chamber. AMSOIL Diesel
Concentrate promotes trouble-free operation. AMSOIL Cold Flow Improver is recommended where fuel oil is stored
outside.
Recommendations
AMSOIL Diesel Concentrate is recommended for use with all types of heavy- and light-duty, on- or off-road and
marine diesel engines. Recommended mix ratio is one oz. of additive per five gallons of fuel. Use with every new
tank of fuel for the best performance and protection against fuel pump wear, injector wear and injector deposits.
Compatible with all types of exhaust emission systems such as diesel particulate filters (DPFs). Add Diesel
Concentrate to fuel before storage. Excellent for use with AMSOIL Cetane Boost and AMSOIL Cold Flow Improver. This
diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and
non-road engines.
Health and Safety
DANGER: COMBUSTIBLE. HARMFUL OR FATAL IF SWALLOWED. HARMFUL IF INHALED OR ABSORBED THROUGH
SKIN. EYE AND SKIN IRRITANT. KEEP OUT OF REACH OF CHILDREN. Read carefully precautions on label of AMSOIL Diesel
Concentrate container before use. For further information, a Material Safety Data Sheet (MSDS) is available upon
