CORE A OIL 7N6672 - Caterpillar

Commercial Oils
If Cat oils cannot be used, the following oil specifications provide guidelines for the selection of commercial products:* If API CF-4 oils are not available then use API CF-4, CF-4/SG. If API CF-4 oils are not available then use API CE, CE/SG, CCMC D4, MIL-L-2104EConsult with your Caterpillar dealer for oil recommendations.Commercial oils 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.
Consult the EMA Lubricating Oils Data Book, SEBU6310, for a listing of oil brands. The percentage of sulfur in the fuel will affect 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 will depend 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.Hydraulic Oil
Cat Hydraulic Oil (HYDO)
Cat Hydraulic Oil is formulated with a balanced additive system, including detergents, rust inhibitors, antiwear agents and defoamers. It will offer 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.If higher viscosities are required because of high ambient temperatures, the following Caterpillar oils can be used:* Cat Diesel Engine Oil DEO (CF-4)* Cat Diesel Engine Oil DEO (CD)* Cat Transmission/Drive Train Oil (TDTO)Biodegradable Hydraulic Oil (BIO HYDO)
Caterpillar now has available a biodegradable oil for use in machine hydraulic systems. This fluid meets the stringent requirements for the hydraulic system components and satisfies customer needs for a hydraulic oil that is readily biodegradable and non-toxic. This oil is formulated with vegetable based oil from the rape seed and selected additives. This oil is to be used in hydraulic systems only, and not in compartments with brakes, clutches, etc.Use of the BIO HYDO is not recommended for operation at tank or actual oil temperatures below -7°C (20°F) or above 82°C (180°F). The oil within the specified temperature range has a viscosity similar to an SAE 10W Oil or the ISO VG of 32 to 46.Contact your Caterpillar dealer for additional information on this new product and its potential use.Commercial Oils
If Cat oils cannot be used, the following commercial classifications can be used in the hydraulic system:* API
