NOTE: Hydraulic oils must have anti-wear qualities at least to API Ser-
vice Classification GL-3, and sufficient chemical stability for
mobile hydraulic system service. JLG Industries recommends
Mobilfluid 424 hydraulic oil, which has an SAE viscosity index of
152.
NOTE: When temperatures remain consistently below 20 degrees F. (-7
degrees C.), JLG Industries recommends the use of Mobil DTE13.

NOTE:
– JLG Lift –
Aside from JLG recommendations, it is not advisable to mix oils of differ-
ent brands or types, as they may not contain the same required addi-
tives or be of comparable viscosities. If use of hydraulic oil other than
Mobilfluid 424 is desired, contact JLG Industries for proper recommenda-
tions.
