Engine Data - Caterpillar 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.
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 Mobilfluid 424 is desired, contact JLG
Industries for proper recommendations.
