The abbreviations listed below follow S.A.E. J754 nomenclature. The classifications follow S.A.E. J183 classifications. The MIL specifications are U.S.A. Military Specifications. These definitions will be of assistance in purchasing lubricants.Engine Oils (CD or CD/TO-2)
Use oils that meet Engine Service Classification CD (MIL-L-2104D) or CD/TO-2. Consult the "EMA Lubricating Oils Data Book," Form SEBU5939, for listing of CD oil brands.Lubricating Grease (MPG)
Use Multipurpose-type Grease (MPG). NLGI No. 2 Grade is suitable for most temperatures. Use NLGI No. 1 or No. 0 Grade for extremely low temperatures.Recommended Lubricant Viscosities
Fuel Specifications
Types of Fuel
Caterpillar Engines have the ability to burn a wide variety of fuels. These fuels are divided into two general groups, Preferred and Permissible.The Preferred Fuels provide maximum engine service life and performance. These are distillate fuels. They are commonly called fuel oil, furnace oil, diesel fuel, gas oil, or kerosene.The Permissible Fuels are crude oils or blended fuels. Use of these fuels can result in high maintenance costs and reduced engine service life.See Caterpillar Form Number SEHS7067 for a detailed summary of Preferred and Permissible Fuels and their specifications.Cetane Requirement
The minimum cetane recommended for the engine:1. (Precombustion Chamber Engine - 35 Cetane.)2. (Direct Injection Engines - 40 Cetane.)Fuel Cloud Point
Fuel waxing can plug the fuel filters in cold weather. The fuel cloud point must be below the temperature of the surrounding air to prevent filter waxing and power loss.Fuel Sulfur Content
The percentage of sulfur in the fuel will affect the engine oil recommendations. If the fuel has over 0.5% sulfur content, the CD engine oil must have a TBN of 20 times the percentage of fuel sulfur (TBN as measured by the ASTM D-2896 method). Your oil supplier should be able to furnish the correct oils.Coolant Specifications
Engine Coolant
Use a mixture of fill water antifreeze and conditioner.Caterpillar Form Number SEBD0518 entitled "Know Your Cooling System" can provide more detailed specifications.Fill Water
Always add conditioner to water. Never use plain water.Acceptable water for use in the ethylene glycol-type antifreeze and water mixture is shown on the chart below: Antifreeze
Use ethylene glycol-type antifreeze. Use the correct amount to provide freeze protection to the lowest expected temperature.Conditioner
Use Caterpillar Cooling System Conditioner or equivalent. Follow the instructions on the container.On a new or reconditioned engine add 1 liter (1 quart) of Caterpillar Cooling System Conditioner, or equivalent, for each 30 liters (8 U.S. gallons) so that the cooling system will have a 3% to 6% concentration of conditioner.If the engine is not equipped with spin-on Coolant Conditioner Elements, add .50 liter (1 pint) of Caterpillar Cooling System Conditioner for each 15 liters (4 U.S. gallons) of coolant used to maintain the 3% to 6%.Cooling Conditioner Elements
Contact your Caterpillar dealer for the correct coolant conditioner element.
