Lubricant Viscosities and Refill Capacities
• Lower fuel economy
• Shorten the time period between oil drain intervals
(more
frequent oil drain intervals).
• Increase overall operating costs.
Failures that result from the use of improper fuels
are
not Cat factory defects. Therefore the cost of
repairs would not be covered by a Cat warranty.
Caterpillar does not require the us
e of ULSD in of
f
road and machine applications that are not Tier 4/
Stage IIIB certified engines. ULSD is not required in
engines that are not equipped with after treatment
devices. For Tier 4/Stage IIIB/Stage IV certified
engines always follow operating instructions. Fuel
tank inlet labels are installed in order to ensure that
the correct fuels are used.
Refer to Special Publication
, SEBU6250, “
Caterpillar
Machine Fluids Recommendations” for more details
about fuels, lubricants, and Tier 4 requirements. This
manual may be found on the Web at Safety.Cat.com.
Fuel Additives
Cat Diesel Fuel Conditioner and Cat Fuel System
Cleaner are available for use when needed. These
products are applicable to diesel and biodiesel
fuels. Consult your Cat dealer for availability.
Biodiesel
Biodiesel is a fuel that can be made from various
renewable resources that include vegetable oils,
animal fat, and waste cooking oil. Soybean oil and
rapeseed oil are the primary vegetable oil sources.
In order to use any of these oils or fats as fuel, the
oils or fats are chemically processed (esterified).
The water and contaminants are removed.
U.S. distillate diesel fuel specification “ASTM D975-
0
9a
” includes up to B5 (5 percent) biodiesel.
Currently, any diesel fuel in the U.S. may contain up
to B5 biodiesel fuel.
European distillate diesel fuel
specification “EN 590
”
includes up to B5 (5 percent) and in some regions
up to B7 (7 percent) biodiesel. Any diesel fuel in
Europe may contain up to B5 or in some regions up
to B7 biodiesel fuel.
Note: The
diesel portion used in the biodiesel blend
must be Ultra Low Sulfur Diesel (15 ppm
sulfur or
less, per “ASTM D975”). In Europe the diesel fuel
portion used in the biodiesel blend must be sulfur
free diesel (10 ppm sulfur or less, per “EN 590”). The
final blend must have 15 ppm sulfur or less.
Note: Up to B20
biodiese
l blend level is acceptable
for use in the engine.
When biodiesel fuel is used, certain guidelines
must
be followed. Biodiesel fuel can influence the engine
oil, aftertreatment devices, non-metallic, fuel system
components, and others. Biodiesel fuel has limited
storage life and has limited oxidation stability. Follow
the guidelines and requirements for engines that are
seasonally operated and for standby power
generation engines.
In order to reduce the risks associated with the use
of
bi
odiesel, the final biodiesel blend and the
biodiesel fuel used must meet specific blending
requirements.
All the guidelines and requirements are provided in
th
e late
st revision of Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations”. This
manual may be found on the Web at Safety.Cat.com.
Coolant Information
The information provided in this “Coolant
Recommendation” section should be used with the
“Lubricants Information” provided in the latest
revision of Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations”. This
manual may be found on the Web at Safety.Cat.com.
The following two types of coolants may be used in
Ca
t die
sel engines:
Preferred – Cat ELC (Extended Life Coolant)
Acce
ptable – Cat D
EAC (Diesel Engine Antifreeze/
Cool
ant)
NOTICE
Never use water alone without Supplemental Coolant
Additiv
es (SCA) or without inhibited coolant. Water
alone is corrosive at engine operating temperatures.
In addition, water alone does not provide adequate
protection against boiling or freezing.
