KEYS TO FUELS, LUBRICANTS AND WATER

FUEL:

Use only distillate fuels (ASTM No. 1 or No. 2 Fuel Oil, or No. 1 D or No. 20 Diesel Fuel Oil are

examples) with a minimum cetane number of 40. 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.

CC:

Use oils which meet Engine Service Classification CC, MIL-L-2104B or MIL-L-46152 in these Diesel

engine crankcases and/or gear compartments.

MPGM:

Use Multipurpose-type Grease which contains both 3 to 5% molybdenum disulfide conforming to MIL-L-

7866, and a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures NLGI No. 1

or No. 0 are suitable for extremely low temperatures.

BATTERY:

Use either distilled water; or, odorless, tasteless drinking water. Do not use mineral water, water con-

taining iron, salt water or softened water.

ENGINE:

Use clean water that is low in scale forming minerals not softened water. When the temperature is below

COOLANT

32 (0 ), a sufficient amount of permanent type anti-freeze must be added to adequately protect your

engine against freezing. Adding Caterpillar Coolant System Conditioner is recommended if protection is

for temperatures above -20 (-29 ).
