If the recommended engine oils, John Deere PLUS-50 or ACEA-E7, ACEA E6, ACEA E5 or ACEA E4, are not used, the oil and filter
change interval is reduced (see DIESEL ENGINE OIL AND FILTER INTERVALS chart). If diesel fuel with a sulfur content greater than 0.05%
is used, the oil and filter change interval is also reduced. 6-Cylinder engines with oil pan option codes 1907, 1908, and 1909 require the oil to
be changed at every 250 hours or less regardless of oil specification used.
