Cat Engine Oils (DEO and EO)
Caterpillar has two oil formulations to provide maximum performance and life in the engines in Caterpillar machines.* Cat Diesel Engine Oil (DEO)* Cat Engine Oil (EO)Cat Diesel Engine Oil (DEO) (certified as API CD) is blended with a diesel engine type additive with strong detergency effectiveness. This oil has a higher alkalinity (13.5 TBN) than many oils for the neutralization of wear-causing combustion products and provides additional protection for higher fuel sulfur and an occasional extended drain period.Cat Engine Oil (EO) is performance rated as: SAE 10W30 - API CF-4 (new category); API CESAE 15W40 - API CF-4 (new category); API CEAPI CD-IISAE 30 - API CD-II; API CDThis oil formulation has strong dispersancy effectiveness along with sufficient alkalinity and low sulfated ash level for the performance requirements of the present day engine designs. By meeting the new API CF-4 performance category, requirements are met for newly designed engines of the future.Commercial Oils
If Cat oils can not be used, the following oil specifications provide guidelines for the selection of commercial products:* API CF-4, API CF-4/SG, API CE, CE/SG, CCMC D4, MIL-L-2104ECommercial oils listed above meeting these specifications may require shortened oil change intervals as determined by close monitoring of oil condition with Scheduled Oil Sampling (S O S).
Failure to follow the oil recommendations can cause shortened engine life due to carbon deposits or excessive wear.
Refer to the EMA Lubricating Oils Data Book, SEBU6310, for a listing of oil brands. The percentage of sulfur in the fuel affects the engine oil recommendations. For fuel sulfur effects, the Infrared Analysis or the ASTM D2896 procedure can be used to evaluate the residual neutralization properties of an engine oil. The sulfur products formation depends on the fuel sulfur content, oil formulation, crankcase blowby, engine operating conditions and ambient temperature.Caterpillar's 20 times rule for TBN (Reference: Oil and Your Engine, SEBD0640) versus fuel sulfur is a general requirement, but it can be modified by used oil analysis. The effectiveness of an oil formulation depends on the additive package. A balanced additive package oil of a lower TBN can be as effective in fuel sulfur neutralization and overall performance as some oils with higher TBN values. S O S (used oil analysis) can show these results.Hydraulics
Cat Hydraulic Oil (HYDO)
Cat Hydraulic Oil is formulated with a balanced additive system, including detergents, rust inhibitors, antiwear agents and defoamers. It offers maximum protection against mechanical wear, rusting and corrosive wear in all hydraulic and hydrostatic transmission systems.Cat Hydraulic Oil should be used to achieve maximum life and performance from hydraulic system components and hydrostatic transmissions. Use of Cat Hydraulic Oil is recommended in most hydraulic and hydrostatic systems.* Cat Hydraulic Oil (HYDO)If higher viscosities are required because of high ambient temperatures, the following Caterpillar engine crankcase oils can be used:* Cat Engine Oil (EO)* Cat Diesel Engine Oil (DEO)Commercial Oils
If Cat oils can not be used, the following commercial classifications can be used in the hydraulic and hydrostatic transmissions:* API CF-4/SG,
