NOTE:
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.

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
standard UTTO hydraulic oil, which has an SAE viscosity index of
152.
When temperatures remain consistently below 20 degrees F. (-7
degrees C.), JLG Industries recommends the use of Mobil DTE13.
