DEO-ULS ____________________ Diesel Engine Oil-Ultra Low SulfurCat DEO-ULS
Cat DEO-ULS is developed and tested in order to provide superior protection and life for your Caterpillar industrial engines.
Better Detergents
Advanced Additive Package
Enhanced Dispersants
Improved Protection from Thermal breakdown and Oxidation BreakdownDue to significant variations in the quality and in the performance of commercially available oils, Caterpillar makes the following recommendations:
Cat DEO-ULS (SAE 10W-30)
Cat DEO-ULS (SAE 15W-40)Cat DEO Multigrade oil is available in various viscosity grades that include SAE 10W-30 and SAE 15W-40. To choose the correct viscosity grade for the ambient temperature, see illustration 1. Multigrade oils provide the correct viscosity for a broad range of operating temperatures. Multigrade oils are also effective in maintaining low oil consumption and low levels of piston deposits.Consult your Caterpillar dealer for part numbers and for available sizes of containers.Note: Cat DEO in SAE 15W-40 passes the following proprietary tests: sticking of the piston ring, oil control tests, wear tests and soot tests. Proprietary tests help ensure that Caterpillar multigrade oil provides superior performance in Caterpillar Diesel Engines. In addition, Cat DEO Multigrade oil exceeds many of the performance requirements of other manufacturers of diesel engines. Therefore, this oil is an excellent choice for many mixed fleets. True high performance oil is produced with a combination of the following factors: industry standard tests, proprietary tests, field tests and prior experience with similar formulations. The design and the development of Caterpillar lubricants that are both high performance and high quality are based on these factors. Commercial Oils
Note: Non-Caterpillar commercial oils are second choice oils.
Caterpillar Strongly Recommend the use of the following specification of engine oil. Failure to use the appropriate specification of engine oil will reduce the life of your engine. The life of the aftertreatment system will also be reduced.

Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Note: Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" for additional information that relates to lubrication for your engine.Lubricant Viscosity Recommendations
The proper SAE viscosity grade of oil is determined by the minimum ambient temperature during cold engine start-up, and the maximum ambient temperature during engine operation. Refer to illustration 1 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.Refer to illustration 1 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated.Note: Generally, use the highest oil viscosity that is available to meet the requirement for the temperature at start-up.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-20 or SAE 0W-30.
Illustration 1 g01918619
Supplemental heat is recommended for cold soaked starts below the minimum ambient temperature. Supplemental heat may be required for cold soaked starts that are above the minimum temperature that is stated, depending on the parasitic load and other factors. Cold soaked starts occur when the engine has not been operated for a period. This action will allow the oil to become more viscous due to cooler ambient temperatures.
S O S Oil Analysis
Caterpillar has developed a tool for maintenance management that evaluates oil degradation and the tool also detects the early signs of wear on internal components. The Caterpillar tool for oil analysis is called S O S Oil Analysis and the tool is part of the S O S Services program. S O S Oil Analysis divides oil analysis into three categories:
Wear Analysis
Oil condition
Additional testsThe wear analysis monitors metal particles, some oil additives, and some contaminants.Oil condition uses infrared (IR) analysis to evaluate the chemistry of the oil. Infrared analysis is also used to detect certain types of contamination.Additional tests are used to measure contamination levels from water, fuel, or coolant. Oil viscosity and corrosion protection can be evaluated, as needed.Refer to Special Publication, SEBU6251, "Caterpillar Commercial Diesel Engine Fluids Recommendations" or contact your local Caterpillar dealer for additional information concerning the S O S Oil Analysis program.Lubrication System
The refill capacities for the engine crankcase reflect the approximate capacity of the crankcase or sump plus standard oil filters. Auxiliary oil filter systems will require additional oil. Refer to the OEM specifications in order to find the capacity of the auxiliary oil filter.

(1) The minimum value is the approximate capacity for the crankcase oil sump (aluminum) which includes the standard factory installed oil filters. Engines with auxiliary oil filters will require additional oil. Refer to the OEM specifications for the capacity of the auxiliary oil filter. The design of the oil pan can change the oil capacity of the oil pan.
