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. It 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. Reduced soot loading controls 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.
