NOTICE
Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or consum-
ables (filters, additives) which are made by other
manufacturers are used on Perkins products, the
Perkins warranty is not affected simply because of
such use.
However, failures that result from the installation
or use of other manufacturers devices, accesso-
ries, or consumables are NOT Perkins defects.
Therefore, the defects are NOT covered under the
Perkins warranty.
Supplemental diesel fuel additives are not generally
recommended. This recommendation is due to
potential damage to the fuel system or the engine.
Your fuel supplier or the fuel manufacturer will add
the appropriate supplemental diesel fuel additives.
Perkins recognizes the fact that additives may be
required in some special circumstances.
Note: Some anti-corrosion additives can lead to
injector fouling, this fouling can cause the injector to
operate incorrectly.
Contact your fuel supplier for those circumstances
when fuel additives are required. Your fuel supplier
can recommend the appropriate fuel additive and the
correct level of treatment.
Note: For the best results, your fuel supplier should
treat the fuel when additives are required. The
treated fuel must meet the requirements that are
stated in table 17 .
Perkins Diesel Fuel System Cleaner
Perkins T40-0012 Fuel Cleaner is the only fuel
cleaner that is recommended by Perkins.
If biodiesel or biodiesel blends of fuel are to be used,
Perkins require the use of Perkins fuel cleaner. The
use of the fuel is to remove deposits within the fuel
system that is created with the use of biodiesel. For
more information on the use of biodiesel and
biodiesel blends refer to "Recommendation for
Biodiesel and Using B20".
Perkins fuel cleaner will remove deposits that can
form in the fuel system with the use of biodiesel and
biodiesel blends. These deposits can create a loss of
power and engine performance.
Once the fuel cleaner has been added to the fuel, the
deposits within the fuel system are removed after 30
hours of engine operation. For maximum results,
continue to use the fuel cleaner for up to 80 hours.
Perkins fuel cleaner can be used on an on-going
basis with no adverse impact on engine or fuel
system durability.
Details instruction on the rate of which the fuel
cleaner must be use are on the container.
Note: Perkins fuel cleaner is compatible with existing
and U.S. EPA Tier 4 nonroad certified diesel engine
emission control catalysts and particulate filters.
Perkins fuel system cleaner contains less than 15
ppm of sulfur and is acceptable for use with ULSD
fuel.
Contamination Control
Recommendations for Fuels
Fuels of "ISO 18/16/13" cleanliness level or cleaner
as dispensed into the engine or application fuel tank
should be used. This will reduce risk of power loss,
fuel system failures, and related down time of
engines. This cleanliness level is important for new
fuel system designs such as common rail injection
systems and unit injectors. These fuels systems
utilize higher fuel injection pressures and have tight
clearances between moving parts to meet required
stringent emissions regulations. Peak injection
pressures in current fuel injection systems may
exceed 2000 bar (29000 psi). Clearances in these
systems are less than 5 µm. As a result, particle
contaminants as small as 4 µm can cause scoring
and scratching of internal pump and injector surfaces
and of injector nozzles.
Water in the fuel causes cavitation, corrosion of fuel
system parts, and provides an environment where
microbial growth in the fuel can flourish. Other
sources of fuel contamination are soaps, gels, or
other compounds that may result from undesirable
chemical interactions in the fuels, particularly in
ULSD. Gels and other compounds can also form in
biodiesel fuel at low temperatures or if biodiesel is
stored for extended periods. The best indication of
microbial contamination, fuel additives, or cold
temperature gel is rapid filter plugging of bulk fuel
filters or application fuel filters.
To reduce downtime due to contamination, follow
these fuel maintenance guidelines.
• Use high-quality fuels per recommended and
required specifications
• Fill fuel tanks with fuels of "ISO 18/16/13"
cleanliness level or cleaner, in particular for
engines with common rail and unit injection
systems. When you refuel the tank, filter the fuel
through a 4 µm absolute filter (Beta 4 = 75 up to
200) to reach the recommended cleanliness level.
This filtration should be installed at the device that
dispenses the fuel to the fuel tank. In addition,
filtration at the dispensing point should remove
water to ensure that fuel is dispensed at 500 ppm
water or less.
