Cat SAEO (Special Application Engine Oil)
Caterpillar recommends the use of Cat SAEO in Cat Marine Diesel Engines covered by this Operation and Maintenance Manual.The factory-fill for these engines is Cat SAEO with the following properties:
Meets all requirements of API CF-4 category
Viscosity grade of SAE 30Caterpillar recommends the following engine oil for maximum performance:
Cat SAEO (SAE 30)
Cat SAEO (SAE 40)Note: Caterpillar recommends the use of single grade oils that pass all API CF-4 category requirements unless crankcase blowby has been routed away from the air cleaner inlet.Commercial Oils
Cat does not warrant the quality or performance of non-Cat fluids.
When Cat SAEO is not used, use the following commercial oils:
Single grade oil with a viscosity of SAE 30 or SAE 40 that meets all API CF category requirements is preferred.
Single grade oil with a viscosity of SAE 30 or SAE 40 with an API CF additive package and no viscosity improvers is acceptable oil.For an acceptable commercial single grade oil, consult your Cat dealer.Some commercial oils that meet the requirements API CF-4 category may require reduced oil change intervals. To determine the oil change interval, closely monitor the condition of the oil and perform a wear metal analysis. Cat S O S Services oil analysis program is the preferred method.
Failure to follow these oil recommendations can cause shortened engine service life due to deposits and/or excessive wear.
Refer to Special Publication, SEBU6251, "Cat Commercial Diesel Engine Fluids Recommendations" in order to obtain additional information about S O S Services oil analysis. You can also contact your local Cat dealer.Total Base Number (TBN) and Fuel Sulfur Levels
The use of Cat S O S Services oil analysis is strongly recommended for determining oil life.Note: The following information concerning oil life relative to used oil TBN level is provided for general information only, and is not the recommended method for determining oil life. If the one half of new oil TBN guideline that is stated below is used for determining oil life it must only be used in conjunction with a complete S O S Services oil analysis program.Note: TBN is also commonly referred to as Base Number (BN).The minimum required Total Base Number (TBN) for oil depends on the fuel sulfur level. For direct injection engines that use distillate fuel, the minimum new oil TBN must be ten times the fuel sulfur level. The TBN for new oil is typically determined by the "ASTM D2896" procedure.Note: The minimum TBN of the new oil is 6.5 regardless of the fuel sulfur level. Reaching one half of new oil TBN is one of the condemning factors for diesel engine oil but, in order to help provide the best protection for your engine, Cat S O S Services oil analysis is the preferred method of determining oil life. For best results when determining oil life using the one half new oil TBN method, determine the new and used oil TBN using both the "ASTM D2896" and the "ASTM D4739" test methods. Change the oil when reaching one half of new oil TBN with either respective TBN test method using the results from which ever respective test method shows reaching one half of new oil TBN first.Excessive piston deposits can be produced by oil with a high TBN and/or high ash. These deposits can lead to a loss of control of the oil consumption and to the polishing of the cylinder bore.
Depending on application severity and localized environmental conditions, and also depending on maintenance practices, operating Direct Injection (DI) diesel engines and operating PC (Precombustion Chamber) diesel engines on fuel with sulfur levels over 0.1 percent (1000 ppm) may require significantly shortened oil change intervals in order to help maintain adequate wear protection.
Consult with your Cat dealer regarding the testing that is required in establishing oil drain intervals that are optimized for your application.Cat S O S Services oil analysis is:
Recommended as a matter of course
Very strongly recommended in order to determine oil drain intervals when operating on fuel with sulfur levels between 0.05% (500 ppm) and 0.5% (5000 ppm)
Required in order to determine oil drain intervals when operating on fuel with sulfur levels that are above 0.5% (5000 ppm)Note: Engine operating conditions play a key role in determining the effect that fuel sulfur will have on engine deposits and on engine wear. Consult your Cat dealer for guidance when fuel sulfur levels are above 0.1% (1000 ppm).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 Table 1 (minimum temperature) in order to determine the required oil viscosity for starting a cold engine.Refer to Table 1 (maximum temperature) in order to select the oil viscosity for engine operation at the highest ambient temperature that is anticipated.Generally, use the highest oil viscosity that is allowed for the ambient temperature at start-up.
Table 1
Lubricant Viscosities for Ambient Temperatures(1)
Cat SAEO
Viscosity Grade Ambient Temperature
Minimum Maximum
SAE 30 0 °C (32 °F) 40 °C (104 °F)
SAE 40 5 °C (41 °F) 50 °C (122 °F)
(1) 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 of time, allowing the oil to become more viscous due to cooler ambient temperatures.S O S Services Oil Analysis
Caterpillar has developed a maintenance tool that evaluates oil degradation. the maintenance management also detects the early signs of wear on internal components. The Cat 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 four categories:
Component wear rate
Oil condition
Oil contamination
Identification of oilThese four types of analys
