Selecting the Viscosity

Ambient temperature is the temperature of the air in the immediate vicinity of the machine. The temperature may differ due to the machine application from the generic ambient temperature for a geographic region. When selecting the proper oil viscosity for use, review both the regional ambient temperature and the potential ambient temperature for a given machine application. Generally, use the higher temperature as the criterion for the selection of the oil viscosity. Generally, use the highest oil viscosity that is allowed for the ambient temperature when you start the machine. Refer to the “Lubricant Viscosities for Ambient Temperatures” tables for guidance. In cold-weather applications, the preferred method is to use properly sized machine compartment heaters and a higher viscosity grade oil. Thermostatically controlled heaters that circulate the oil are preferred.

The proper oil viscosity grade is determined by the minimum ambient temperature (the air in the immediate vicinity of the machine). Ambient temperature is the temperature when the machine is started and while the machine is operated. To determine the proper oil viscosity grade, refer to the “Min” column in the table. This information reflects the coldest ambient temperature condition for starting a cold machine and for operating a cold machine. Refer to the “Max” column in the table to select the oil viscosity grade 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 when you start the machine.

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 higher oil viscosity will maintain the highest possible oil film thickness. Refer to this Special Publication, General Information for Lubricants article, Lubricant Viscosities tables, and any associated footnotes. Consult your Cat dealer if additional information is needed.

Note: SAE 0W and SAE 5W oils, where allowed for use in non-hydraulic system compartments, are not recommended for use in machines that are operated continuously and/or are heavily loaded. Refer to the “Lubricant Viscosities for Ambient Temperatures” tables for guidance. The oils that have the higher oil viscosity will maintain the highest possible oil film thickness. Consult your Cat dealer if additional information is needed.

Note: Oil viscosity grade selection is also machine compartment specific. Some machine models and/or machine compartments do not allow the use of all available viscosity grades. For guidance on selecting oil viscosity, refer to the “Lubricant Viscosities for Ambient Temperatures” tables.

Note: Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.


NOTICE

Proper oil viscosity AND oil type/specification are required to maximize machine compartment performance and life. Do NOT use only oil viscosity, or only oil type to determine the machine compartment oil selection. Using only the oil viscosity or only the oil type to determine a machine compartment oil selection can lead to reduced performance and compartment failure. Refer to the “Lubricant Viscosities for Ambient Temperatures” tables and to ALL of the associated footnotes.



NOTICE

Not following the recommendations found in the “Lubricant Viscosities for Ambient Temperatures” tables and associated footnotes can lead to reduced performance and compartment failure.



NOTICE

In colder ambient conditions a machine warm-up procedure and/or supplemental machine fluid compartment heat may be required. Machine specific warm-up procedures can typically be found in the Operation and Maintenance Manual for the machine. In addition, generic machine warm-up procedures can be found in this Special Publication, "Procedures for Machines that are Used in Cold Weather - (Generic)" topic.


General Information for Lubricants

The information provided in this “Lubricant Viscosities for Ambient Temperatures” article and Tables should be used with the information provided in the “Lubricant Specifications” section (Maintenance Section) of this Special Publication.


NOTICE

Cat does not warrant the quality or performance of non-Cat fluids and greases.



NOTICE

Not following the recommendations found in this Special Publication can lead to reduced performance and compartment failure.



NOTICE

Do NOT use only the oil viscosities when determining the recommended oil for an engine compartment. The oil type (performance requirements) MUST also be used.


Note: Some machine models and/or machine compartments do NOT allow the use of all available oil viscosity grades.

Note: Only use the oil type and the specification that is recommended for the various machine compartments.

Note: Some machine compartments allow the use of more than one oil type. For the best results, do not mix oil types.

Note: Different brand oils may use different additive packages to meet the various machine compartment performance specification recommendations. For the best results, do not mix oil brands.

Note: The availability of the various Cat oils will vary by region.

Note: Cat oils are the preferred oils. All other oil types and specifications that are listed in the applicable section are acceptable oils.

The minimum requirements for commercial oils for machine components are provided in Table 1 of this Special Publication. These requirements apply to all the fluids recommendations given in this Special Publication. Commercial oils are, as a group, second choice oils.

The factory fill oils for standard configuration machines are indicated in the lubricant recommendations tables, where pertinent. Factory fill information is general and exceptions may exist. For example, machines that are shipped to cold climates may have other factory fill oils.

When you are operating the machine in temperatures below −20°C (−4°F), refer to Special Publication, SEBU5898, "Cold Weather Recommendations". This publication is available from your Cat dealer.

For cold-weather applications where transmission oil SAE 0W-20 is recommended, Cat TDTO Cold Weather is the first choice oil. Second choice oils for cold-weather transmission applications are commercial oils of full synthetic basestock that do not have viscosity index improvers. These oils do meet the Cat TO-4 performance requirements. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Oils of lubricant viscosity grade SAE 0W-20, SAE 0W-30, or SAE 5W-30 that contain a Cat TO-4 additive package are a last choice.

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

Table 3 is for all Cat machine hydraulic systems and machine hydrostatic transmissions. This table applies to all oils that are recommended for the machine hydraulic systems, pumps, and valves. This table applies to all oils that are recommended for the machine hydrostatic transmissions.

All other tables are listed in the product line categories. These tables contain information about other machine and Expanded Mining products compartments and the lubrication recommendations for each compartment. Some machine compartments allow the use of more than one oil type. Some machine and Expanded Mining products compartments restrict the use of some oil types. These tables contain any exceptions to tables 9 and 3. Consult your Cat dealer if additional information is needed about any of the exceptions.

Special applications are included at the end of this section. Special applications include starting engine and variable pitch fan. If you do not find a compartment in the product category, check this table. Consult your Cat dealer if additional information is needed about special applications.

Note: Exceptions to any information in the common tables are listed in the tables in the product line sections.

All Cat Machine and Expanded Mining Products Engines

Refer to the “General Information for Lubricants” article for important lubricant information.

Supplemental heat is recommended for cold-soaked starts below the minimum ambient temperature. The parasitic load and other factors will determine if supplemental heat is required for cold-soaked starts that are above the minimum temperature that is stated. Cold-soaked starts occur when the engine has not been operated for a time. The oil becomes more viscous due to cooler ambient temperatures.

For oil recommendations for Tier 4 EPA certified engines, EU stage IIIB and IV type approved engines, and Japan Step IV approved engines refer to the “Recommendation for Tier 4 Engines” section, the “Cat Engine Lubricants Recommendations/Requirements” table, and the “TBN recommendations for applications in Cat engines” table in Special Publication, SEBU6250, "Engine Oil".

Refer to the “Lubricant Information” section in this Special Publication for a list of all Cat engine oils.

Cat ECF refers to Engine Crankcase Fluid specifications. Refer to the “Maintenance” section of this Special Publication, "Lubricant Information", and to the “Cat Engine Crankcase Fluids (ECF) Definitions” table in this Special Publication, "Engine Oil" for details. Commercial alternative diesel engine oils must meet one or more of these Cat ECF specifications. Refer to the “Cat Engine Lubricants Recommendations/Requirements” table in Special Publication, SEBU6250, "Engine Oil".

The minimum requirements for commercial diesel engine oils are provided in Special Publication, SEBU6250, "Engine Oil (Cat Machine Diesel Engines)". These requirements apply to all the fluids recommendations given in this Special Publication. Commercial alternative diesel engine oils are, as a group, second choice oils.

Note: Cat Special Application Engine Oil (SAEO), API CF oil of SAE 30 and SAE 40 viscosity grades is recommended for use in 3116 and 3126 marines engines.

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).

Note: C175 Series diesel engines require the use of multigrade SAE 40 oil. For example: SAE 0W-40, SAE 5W-40, SAE 10W-40, or SAE 15W-40. In ambient temperatures of −9.5° C (15° F) or above, SAE 15W-40 is the preferred oil viscosity grade

If ambient temperature conditions at engine start-up require the use of multigrade SAE 0W oil, SAE 0W-40 viscosity grade is preferred over SAE 0W-30.

All Cat Machine Hydraulic Systems and Machine Hydrostatic Transmissions

Refer to the “General Information for Lubricants” article for important lubricant information.

Cat HYDO Advanced 10 SAE 10W, Cat HYDO Advanced 20 SAE 20W, Cat HYDO Advanced 30 SAE 30W, or Cat BIO HYDO Advanced are the preferred oils for use in most Cat machine hydraulic and hydrostatic transmission systems. Cat HYDO Advanced fluids have at least a 50% increase in the standard oil drain interval for machine hydraulic systems (3000 hours versus 2000 hours) over second and third choice oils - when following the maintenance interval schedule for oil filter changes and for oil sampling that is stated in the Operation and Maintenance Manual for your particular machine. 6000 hour oil drain intervals are possible when using S·O·S Services oil analysis. Consult your Cat dealer for details. To gain the most benefit from the improved performance designed into Cat HYDO Advanced fluids, when switching to Cat HYDO Advanced fluids, cross contamination with the previous oil should be kept to less than 10%.

Second choice oils are Cat MTO, Cat DEO, Cat DEO-ULS, Cat TDTO, Cat Cold Weather TDTO, Cat TDTO-TMS, Cat Cold Weather DEO-ULS.

Third choice oils are commercial oils that meet Cat ECF-1-a, Cat ECF-2, Cat ECF-3 (which can include viscosity grades not given in Table3), Cat TO-4, or the Cat TO-4M performance requirements, and that have a minimum zinc additive level of 0.09 percent (900 ppm). Commercial biodegradable hydraulic oil must meet the Cat BF-2 specification. Refer to the machine Operation and Maintenance Manual and/or consult your local Cat dealer before using commercial oils that meet Cat BF-2 in Cat Hydraulic Excavators.

The minimum viscosity for commercial alternative oils used in most Cat machine hydraulic and hydrostatic transmission systems is 6.6 cSt at 100 °C (212 °F) ("ASTM D445").

Note: Industrial hydraulic oils are not recommended for service fill in AVSpare hydraulic systems.

Note: For machines equipped with hydraulic hammers, do not use viscosity grades SAE 0W or SAE 5W oils. Refer to the “Special Applications” section in this article.

For applications requiring the use of Fire-Resistant hydraulic fluids or Food-Grade hydraulic fluids, refer to the information on these two types of fluids given in the Hydraulic Oil Section of this Special publication.

Commercial oils of viscosity grades that are not included in Table 10 may be used if the oils are per Cat ECF specifications. Refer to the  "Cat Engine Crankcase Fluids (ECF) Definitions " table in the "Engine Oil" section of this Special Publication. Commercial oils are second choice.

If noise is a problem in the hydraulic system, 1U-9891 oil additive may be used in the hydraulic system. This additive is a friction modifier that helps reduce the noise level.

Table 3 describes the hydraulic system recommendations for all Cat machines. Some machines require different temperature ranges or specific hydraulic fluids. The recommendations for those machines are given in the respective machine Lubricant Viscosity Table.

Off Highway Trucks

Refer to the “General Information for Lubricants” article for important lubricant information.

This section includes, but not limited to the following models:

  • 769 through 797

  • MT4400D AC, 794 AC, 796 AC, and 798 AC

Some Off-Highway Truck torque converters have a common sump with the transmission. These torque converters will use the same fluid recommendations as the transmission. The affected Off-Highway Truck models include 769D, 770, 771D, 772, 773D, 773E, 773F, 775D, 775E, 775F, 793C-F, and all 797 models.

Cat FDAO SYN and Cat FDAO SAE 60 are preferred in Differential, Front Wheel, and Final Drive applications. Cat FDAO SYN is the preferred oil for extremely cold or hot environments, for maximum component life, and for extending the rear axle oil change intervals. If the ambient temperature is below −10°C (14°F) for FDAO SAE 60 or below −35°C (−31°F) for FDAO SYN, warm up the oil prior to operation by performing the procedures in the Operation and Maintenance Manual, "Differential Warm-up and Break-in" prior to operation. Failure to warm up the oil prior to operation can damage the machine.

Note: The minimum acceptable viscosity for commercial alternative oils in most Cat machine hydraulic and hydrostatic transmission systems is 6.6 cSt at 100 °C (212 °F) ("ASTM D445").

For hydraulic systems that are not given in Table 10, refer to the hydraulic system recommendations given in Table 3.
