Information:

Consult with your Caterpillar dealer for the latest lubrication recommendations.Fuel Sulfur
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 which was developed in the early 1980s for Caterpillar prechamber combustion system (PC) engines with the oil formulations of that era. The fuel sulfur neutralization of today's newer oil formulations along with direct injection combustion system (DI) engines are more effective. Field results indicate that DI engines and the oils now recommended for these engines will operate at an oil TBN equal to 10 times the fuel sulfur.Therefore, the Caterpillar requirements will reflect this new value of 10 times instead of 20 times for oil TBN when related to fuel sulfur for Cat DI engines and the API CF-4 oils. Used oil analysis should be a part of the overall program to provide the assurance that a particular engine installation with all its parameters (engine, oil, operation, maintenance and fuel) are under control.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.* Cat Hydraulic Oil (HYDO)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 and hydrostatic transmissions. This oil meets the stringent requirements for the hydraulic system components and satisfies customer needs for a hydraulic oil that is readily biodegradable and nontoxic.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.For BIO HYDO oil, continuous heavy duty operation is limited to +32°C (90°F) ambient temperature. Operation at ambient temperatures above +32°C (90°F) should be limited to light duty cycles and short periods of time. Do not use BIO HYDO oil in hydraulic systems with clutches or brakes.Contact your Caterpillar
