NOTE: Hydraulic oils must have anti-wear qualities at least to API
Service Classification GL-3, and sufficient chemical sta-
bility for mobile hydraulic system service. JLG Ind. recom-
mends Mobilfluid 424 hydraulic oil, which has an SAE
viscosity index of 152.
NOTE: When temperatures remain consistently below 20° F (-7°
C), JLG Industries recommends the use of Mobil DTE-13.
NOTE: Machines may be equipped with Mobil EAL224H biode-
gradable and non-toxic hydraulic oil. This is Vegetable oil
based and possesses the same antiwear and rust protec-
tion characteristics as mineral oils, but will not adversely
affect the ground water or the environment when spilled
or leaked in small amounts. Mobil EAL224H has a viscos-
ity of 34 cSt at 40° C. and viscosity index of 213. The
operating temperature range of this oil is -18° C to +83° C.

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.
