Usage:
FUEL: Use only distillate fuels (ASTM No. 1 or No. 2 Fuel Oil, or No. 1D or No. 2D Diesel Fuel Oil are examples) with a minimum cetane number of 35. Heavier oil is generally preferable because of its higher energy content.
CD: Use oils which meet Engine Service Classification CD, or MIL-L-2104C, in Caterpillar diesel engine crankcases and gear compartments.
MPG: Use Multipurpose-type Grease (MPG). Multipurpose-type Grease which contains 3 to 5% molybdenum disulfide is also acceptable, and preferred. NLGI No. 2 Grade is suitable for most temperatures. NLGI No. 1 or No 0 are suitable for extremely low temperatures.
ENGINE COOLANT: Use clean water that is low in scale forming minerals, not softened water. When the temperature is below 32°F (0°C), a sufficient amount of permanent-type antifreeze must be added to adequately protect your engine against freezing. Add enough Caterpillar Corrosion Inhibitor, or equivalent, so that the cooling system will have a 3% concentration of inhibitor at initial fill (one pint/4 gallons). Every 500 Service Meter Units, add 1 pint per 16 gallons of coolant capacity.
