list of Cat engine oils and for detailed information. This manual may be found on
the Web at Safety.Cat.com.

The footnotes are a key part of the tables. Read ALL footnotes that pertain to the
machine compartment in question.

Selecting the Viscosity

To select the proper oil for each machine compartment, refer to the “Lubricant
Viscosity for Ambient Temperature” table. Use the oil type AND oil viscosity for
the specific compartment at the proper ambient temperature.

The proper oil viscosity grade is determined by the minimumambient

temperature (the air in the immediate vicinity of the machine). Measure the
temperature when the machine is startedand while the machine is operated. To
determine the proper oil viscosity grade, refer to the “Min” columninthe table.
This information reflects the coldest ambient temperature condition for startinga
cold machine and foroperating a cold machine. Refer to the “Max” column in the
table for operating the machine at the highest temperature that is anticipated.

 Unless specified otherwise in the “Lubricant Viscosities for Ambient
Temperatures” tables, use the highest oil viscosity that is allowed for the ambient
temperature.

Machines that are operated continuously should use oils that have the higher oil
viscosity in the final drives and in the differentials. The oils that have the higheroil
viscosity will maintain the highestpossible oil film thickness. Refer to “General
PPT
Information for Lubricants” article, “Lubricant Viscosities” tables, and any

202 -4000
associated footnotes. Consult your Cat dealer if additional information is
needed.

Cat oils have been developed and tested to provide the full performance and life

Cat DEO-ULS multigrade and Cat DEO multigrade oils are formulated with the
correct amounts of detergents, dispersants, and alkalinity to provide superior
performance in Cat diesel engines where recommended for use.

Note: SAE 10W-30 is the preferred viscosity grade for the 3116, 3126, C7, C-9,
and C9 diesel engines when the ambient temperature is between -18° C (0° F)
and 40° C (104° F).

Grease
To use a non-Cat grease, the supplier must certify that the lubricant is compatible
with Cat grease.

Each pin joint should be flushed with the new grease. Ensure that all old grease

Diesel Fuel Recommendations

Diesel fuel must meet “Caterpillar Specification for Distillate Fuel” and the latest
versions of "ASTM D975" or "EN 590" to ensure optimum engine performance.

https://sis2.cat.com/?_ts=1718182329133#/print-preview/service/fa3f1d81-516f-41c9-b848-e3838d2ecfdf 28/07/2024 09 55

 Refer to Special Publication, SEBU6250 , "Caterpillar Machine Fluids
Recommendations" for the latest fuel information and for Cat fuel specification.
This manual may be found on the Web at Safety.Cat.com.

The preferred fuels are distillate fuels. These fuels are commonly called diesel
fuel, furnace oil, gas oil, or kerosene. These fuels must meet the “Caterpillar
Specification for Distillate Diesel Fuel for Off-Highway Diesel Engines”. Diesel
Fuels that meet the Caterpillar specification will help provide maximum engine
service life and performance.

Misfueling with fuels of high sulfur level can have the following negative
effects:

Reduce engine efficiency and durability

Increase the wear

Increase the corrosion

Increase the deposits

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. 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 D975-09a" includes up to B5 (5

percent) biodiesel. Currently, any diesel fuel in the U.S. may contain up to B5
biodiesel fuel.

PPT
European distillate diesel fuel specification "EN 590" includes up to B5 (5

202 -4000
percent) and in some regions up to B7 (7 percent) biodiesel. Any diesel fuel in

4 637
Europe may contain up to B5 or in some regions up to B7 biodiesel fuel.

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

Cat
oxidation stability. Follow the guidelines and requirements for engines that are

seasonally operated and for standby power generation engines.

To reduce the risks associated with the use of biodiesel, the final biodiesel blend

and the biodiesel fuel used must meet specific blending requirements.

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 Cat diesel engines:

Preferred - Cat ELC (Extended Life Coolant)

Acceptable - Cat DEAC (Diesel Engine Antifreeze/Coolant)

NOTICE
Never use water alone as a coolant. Water alone is corrosive at
engine operating temperatures. In addition, water alone does
not provide adequate protection against boiling or freezing.
