Diesel Injector Clean + Cetane Boost
is specially engineered to defend your engine and fuel system against
performance-robbing wear and deposits. Its concentrated formula
provides dependable protection in warm weather. One dose delivers
outstanding detergency, improved lubricity and higher cetane. It is safe
for use in all diesel fuels, including biodiesel.
Restores Horsepower & Improves Fuel Economy
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 can be 30,000 psi and higher to 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.
Diesel Injector Clean + Cetane Boost features advanced chemistry that delivers
concentrated strength to target internal diesel injector deposits and traditional carbonaceous
deposits, helping to restore horsepower and operability to like-new condition.
Acceleration is improved and, with regular use, Diesel Injector Clean + Cetane Boost
continues to enhance performance by keeping injectors clean. The net savings on fuel
can result in no additional cost of ownership.

Lubricates Pumps & Injectors to Reduce Wear
Ultra-low-sulfur diesel fuel (ULSD) provides significantly reduced lubricity – a critical
property in controlling wear in fuel pumps and injectors. Diesel Injector Clean +
Cetane Boost adds back the lubricity the fuel pump and injectors need, reducing wear,
improving service life and saving time and money on maintenance costs.
Improves Fuel Quality for Peak Performance
Fuel with a higher cetane number provides for a more complete burn, resulting in
improved performance. By increasing cetane, Diesel Injector Clean + Cetane Boost
improves the ignition quality of diesel fuel, maximizing available power and improving
starting. It also smooths idle and reduces smoke and emissions.

Extends Filter Life
Modern diesel engines run hot,
raising the temperature of the fuel
returned to the tank and causing
carbonaceous deposits that collect
in the fuel filter (see picture),
plugging it and causing premature
failure issues. AMSOIL Diesel Injector Clean + Cetane Boost
effectively protects against deposits, extending
fuel filter life.
RECOMMENDATIONS
Diesel Injector Clean + Cetane Boost is recommended for
use with all types of heavy- and light-duty, on- or off-road
and marine diesel engines. Add before filling tank. Initial
use: follow clean-up recommendation. Subsequent uses/regular treatment: follow maintenance recommendation.
To prevent cold-weather fuel issues, add AMSOIL Diesel Cold
Flow or switch to AMSOIL Diesel All-In-One.
