Hydraulic Oil
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.
Aside from JLG recommendations, it is not advisable to mix oils
of different brands or types, as they may not contain the same
required additives or be of comparable viscosities. If use of
hydraulic oil other than Mobil DTE 10 is desired, contact JLG
Industries for proper recommendations.
