Diesel Engine Oil and Filter Service Intervals
The oil and filter service intervals in the following
charts should be used as guidelines. Actual service
intervals depend on operation and maintenance
practices. Use oil analysis to determine the actual
useful life of the oil and to aid in selection of the
proper oil and filter service interval.
Oil and filter service intervals are based on a
combination of oil pan capacity, type of engine oil and
filter used, and sulfur content of the diesel fuel.
Diesel fuel sulfur level will affect engine oil and filter
service intervals. Higher fuel sulfur levels reduce oil
and filter service intervals as shown in the table:
Use of diesel fuel with sulfur content less than
0.05% (500 ppm ) is strongly recommended.
Use of diesel fuel with sulfur content 0.05% (500
ppm) to 0.50% (5000 ppm) may result in REDUCED
oil and filter change intervals as shown in the table.
BEFORE using diesel fuel with sulfur content greater
than 0.50% (5000 ppm), contact your John Deere
dealer.
Oil types (premium or standard) in the tables include:
“Premium Oils” include John Deere PLUS-50,
ACEA E7, ACEA E6, ACEA E5 or ACEA E4 oils.
“Standard Oils” include John Deere TORQ-GARD
SUPREME, API CI-4 PLUS, API CI-4, , API CH4
or ACEA E3 oils.
NOTE: The 500 hour extended oil and filter change
interval is allowed only if
ALL
the following
conditions are met:
Engine equipped with an oil pan that allows capacity
for this extended drain interval.
Use of premium oil John Deere PLUS-50, ACEA E7,
ACEA E6, ACEA E5 or ACEA E4
Use of an approved John Deere oil filter
Use of diesel fuel with sulfur content less than
0.05% (500 ppm)
Refer to the charts on the following pages to find the
proper oil and filter service interval for your engine.
Using Charts to Find Oil and Filter Service Interval
1. Determine your engine model and power rating and
find it in the left column of 4.5 L or 6.8 L chart.
2. Locate your engine oil pan option code (19__) on
engine label.
3. In the chart column under your oil pan code, select
whether you use premium oil (PLUS-50 or
equivalent) or standard grade oil.
4. Determine the sulfur content of your diesel fuel.
5. Now you can find the proper oil and filter change
interval by lining up your power level and fuel sulfur
content with oil pan/oil type column. The number
indicates how frequent your oil and filter should be
changed (example: every 500 hours of operation).
