Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical stabil-
ity 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.
