Total Base Number TBN and Fuel Sulfur Levels for Caterpillar Direct Injection Diesel Engines Caterpillar Fluids

146 used for engines and for machines are offered by Caterpillar dealers. Caterpillar fluids are also offered for continued refills. Consult your Caterpillar dealer for more information on these Caterpillar fluids. Caterpillar recommends the use of the following Caterpillar fluids: ar Multigrade Diesel Engine Oil DEO ar TransmissionDrive Train Oil TDTO ar Multipurpose Tractor Oil MTO ar Hydraulic Oil HYDO ar Biodegradable Hydraulic Oil HEES ar Gear Oil GO ar Multipurpose Lithium Grease MPG ar Multipurpose Molybdenum Grease ar Special Purpose Grease SPG ar Premium Grease CPG ar Extended Life Coolant ELC ar Diesel Engine AntifreezeCoolant CATERPILLAR DIESEL ENGINE OIL DEO Caterpillar DEO has been formulated with detergents, with dispersants, and with sufficient alkalinity in order to provide superior performance in Caterpillar diesel engines. The multigrade DEO is blended in SAE 10W30 and in SAE 15W40. Use the table of lubricant viscosities to choose the correct viscosity grade that is based on ambient temperatures. Multigrade oils provide the correct viscosity for a broad range of operating temperatures and for cold engine starts. Multigrade oils are also effective in maintaining low oil consumption and low concentrations of deposits on the pistons. For maximum performance in the engines in Caterpillar machines, Caterpillar recommends the following engine oil:

1. Diesel Engine Oil DEO

Multigrade DEO can be used in other diesel engines and in gasoline engines. Consult the engine manufacturers guide for the recommended specifications. Compare the engine manufacturers specifications to the specifications of Caterpillar DEO. The current Caterpillar specifications are listed on the label and on the product data sheets. • Caterpil • Caterpil • Caterpil • Caterpil • Caterpil • • Caterpil • • Caterpil • Caterpil MPGM 147

2. Commercial Diesel Engine Oils

The performance of commercial diesel engine oils is based on API categories. The API categories were developed in order to provide commercial lubricants for a wide variety of diesel engines that operate at various conditions. When a Caterpillar DEO is not used, use the following commercial oils: • Multigrade API CG-4 Preferred alternative • Multigrade API CF-4 Acceptable alternative The following explanations of these API categories can be used in order to make the proper choice of a commercial oil.

3. Lubricant Specifications

Lubricant Information General Information The information that is provided is the latest recommendations for Caterpillar engines and for Caterpillar machine compartments. This information supersedes all previous recommendations which have been published for Caterpillar machines. Special lubricants are required for some machine compartments and it will be necessary to continue to use these special products. This information is only for Caterpillar machines. For more lubricant recommendations, refer to Operation and Maintenance Manual, SEBU6251, Caterpillar Commercial Diesel Engine Fluid Recommendations, Operation and Maintenance Manual, SEBU6385, Caterpillar On-Highway Diesel Truck Engine Fluid Recommendations, Operation and Maintenance Manual, SEBU6400, Caterpillar Gaseous Fueled Spark Ignited Engines Lubricant Recommendations, and Operation and Maintenance Manual, SEBU7003, Caterpillar 3600 Series Diesel Engine Fluid Recommendations. Engine Oil The Engine Oil Licensing and Certification System for engine oils by the American Petroleum Institute is recognized by Caterpillar. For detailed information about this system, see the thirteenth edition of the API publication No. 1509. Engine oils that bear the API symbol are authorized by API. Examples of the API symbol are shown in Illustration 68.
