Lubricant Viscosities

Usage:

2290 P2D

The proper oil viscosity grade is determined by the minimum outside temperature when the machine is started. The proper oil viscosity grade is also determined by the maximum outside temperature while the machine is operated. Use the column that has the title of "Min" on the table to determine the oil viscosity grade that is required for starting a cold machine. Use the column that has the title of "Max" on the table to determine the oil viscosity grade for operating the machine at the highest temperature that is anticipated. Use the oil with the highest viscosity that is allowed for the ambient temperature when you start the machine.

Machines that are continuously operated should use the oils with the higher viscosity in the final drives and differentials in order to maintain the highest possible oil film thickness. Consult your Caterpillar dealer if additional information is needed.

The oil viscosity grade is specific to the machine compartment. Some machine models and/or machine compartments do not allow the use of all available viscosity grades. For guidance on selecting the oil viscosity, refer to the "Lubricant Viscosities for Ambient Temperatures" table and the associated footnotes in the table. Refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for detailed information.

NOTICE

In selecting oil for any engine application, both the oil viscosity and oil performance classification/specification as specified by the engine manufacturer must be defined and satisfied. Using only one of these parameters will not sufficiently define oil for an engine application.

Note: Some machine compartments allow the use of more than one oil type. For the best results, do not mix oil types. Different brands of oils may use different additive packages. For the best results, do not mix oil brands.

^( 1 )	CAT DEO-ULS oil is Ultra Low Sulfur (15W-40)
^( 2 )	API CI-4, API CI-4 PLUS, and API CH-4 oils are acceptable if the requirements of Caterpillar ECF-1 (Engine Crankcase Fluid specification -1) are met. API CI-4, API CI-4 PLUS, and API CH-4 oils that have not met the requirements of Caterpillar ECF-1 specification may cause reduced engine life.
^( 3 )	SAE 10W-30 is the preferred viscosity grade for the C-9 diesel engines when the ambient temperature is between −18 °C (0 °F) and 40 °C (104 °F).
^( 4 )	Cat HYDO Advanced 10 is the preferred oil for use in most Caterpillar machine hydraulic and hydrostatic transmission systems when ambient temperature is between −20 °C (−4 °F) and 40 °C (104 °F). Cat HYDO Advanced 10 has an SAE viscosity grade of 10W. Cat HYDO Advanced 10 has 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.
^( 5 )	Second choice oils are Cat HYDO, Cat MTO, Cat DEO, Cat DEO-ULS, Cat TDTO, Cat Arctic TDTO, Cat TDTO-TMS, Cat DEO SYN, Cat Arctic DEO SYN. Third choice oils are commercial oils that meet Cat ECF-1-a, Cat ECF-2, Cat ECF-3, Cat TO-4, or the Cat TO-4M specifications, and that have a minimum zinc additive level of 0.09 percent (900 ppm). Commercial biodegradable hydraulic oil must meet the Cat BF-1 specification. Refer to the machine Operation and Maintenance Manual and/or contact your local Caterpillar dealer before using commercial oils that meet Cat BF-1 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").
^( 6 )	Commercial biodegradable hydraulic oil (HEES) must meet the Caterpillar BF-1 specification.
^( 7 )	SAE 15W40 is the recommended viscosity grade for the hydraulic hood tilt system.
^( 8 )	Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the Cat TO-4M multigrade specification requirements)
^( 9 )	Cat MTO is the preferred viscosity grade for the hydraulic hood tilt system when the ambient temperature is below −15 °C (+5 °F) and does not go above 40 °C (104 °F).
^( 10 )	First Choice: Cat Arctic TDTO synthetic blend SAE 0W-20. Second Choice: Oils of full synthetic basestock that do not have viscosity index improvers and do meet the performance requirements of the Cat TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Third Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
^( 11 )	First Choice: Oils of full synthetic basestock that do not have viscosity index improvers and do meet the performance requirements of the Cat TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Second Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
^( 12 )	Cat Engine Crankase Fluid Specifications.
^( 13 )	First Choice Oil: Full synthetic oils are recommended. Synthetic oils may provide longer service life for the fan. Synthetic oils allow for increased service intervals over non-synthetic oils.
^( 14 )	Second Choice Oil: Cat TDTO or commercial oils that meet the Cat TO-4 specification. Cat TDTO is non-synthetic. Commercial TO-4 oils are typically non-synthetic.
