(1)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 Total Base Number (TBN) of 20 times the percentage of fuel sulfur (TBN as measured by the ASTM D-2896 method). If the sulfur content is greater than 1.5% by weight, use an oil with a TBN of 30 and reduce the oil change interval by one half. Consult your Caterpillar dealer for correct engine oil recommendations.(2)The element can be cleaned approximately 4 times. Carefully inspect the element after each cleaning. If engine is not equipped with air cleaner service indicator, check element every 250 service meter units, or more often under dusty conditions. If after servicing the air cleaner, the exhaust smoke and/or loss of power continues, install a new element.
