Oil Consumption as an Overhaul Indicator
Oil consumption, fuel consumption, and maintenance information can be used to estimate the total operating cost for your Caterpillar engine. Oil consumption can also be used to estimate the required capacity of a makeup oil tank that is suitable for the maintenance intervals.Oil consumption is in proportion to the percentage of the rated engine load. As the percentage of the engine load is increased, the amount of oil that is consumed per hour also increases.The oil consumption rate (brake specific oil consumption) is measured in grams per kW/h (lb per bhp). The brake specific oil consumption (BSOC) depends on the engine load. Consult your Caterpillar dealer for assistance in determining the typical oil consumption rate for your engine.When an engine's oil consumption has risen to three times the original oil consumption rate due to normal wear, an engine overhaul should be scheduled. There may be a corresponding increase in blowby and a slight increase in fuel consumption.Overhaul Recommendation
Caterpillar recommends replacement of the engine. For more information about replacement of the engine, see your Caterpillar dealer. Engine components are available in a standard size only.Cleaning
Caterpillar recommends the use of Hydrosolv Liquid Cleaners. Table 1 lists the Hydrosolv Liquid Cleaners that are available from your Caterpillar dealer.

The concentration of supplemental coolant additive (SCA) should be checked regularly with test kits or with S O S Coolant Analysis (Level I).A coolant analysis can be conducted in order to verify the condition of the water that is being used in the cooling system. A full water analysis can be obtained by consulting your local water utility company or an agricultural agent. Private laboratories are also available for water analysis.Caterpillar Inc. recommends an S O S Coolant Analysis (Level II).S O S Coolant Analysis (Level II)
An S O S Coolant Analysis (Level II) is a comprehensive coolant analysis which completely analyzes the coolant and the effects on the cooling system. An S O S Coolant Analysis (Level II) provides the following information:
Complete S O S Coolant Analysis (Level I)
Visual inspection of properties
Identification of metal corrosion
Identification of contaminants
Identification of built up impurities (corrosion and scale)S O S Coolant Analysis (Level II) provides a report of the results of both the analysis and the maintenance recommendations.For more information about coolant analysis, see your Caterpillar dealer.
