1.7 LUBRICATION
Engine (Crankcase) Oil
NOTE: Crankcase oil must be a high quality detergent type
meeting one of the following API service classifica-
tions: CC/SE, CC/SF, CD/SE, CD/SF, CE/SF or CE/
SG.l
Hydraulic Oil
NOTE: Hydraulic oils must have anti-wear qualities at least
to API Service Classification GL-3, and sufficient
chemical stability for mobile hydraulic system ser-
vice. JLG Industries recommends Mobilfluid 424
hydraulic oil, which has an SAE viscosity index of
152 or Kendall Hyken 052 hydraulic oil, which has an
SAE viscosity of 10W-20 and viscosity index of 152.
NOTE: When temperatures remain consistently below -7
degrees C. (20 degrees F.), JLG Industries recom-
mends the use of Mobil DTE11.
NOTE: 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 Indus-
tries for proper recommendations.
Some machines may be specially equipped with Mobil
EAL224H biodegradable and non-toxic hydraulic oil. This
oil is vegetable oil based and possesses the same anti-
wear and rust protection characteristics as mineral oils,
but will not adversely affect ground water or the environ-
ment when spilled or leaked in small amounts. Mobil
EAL224H has a viscosity of 34 cST at 40° C and a viscosity
index of 213. The operating range of this oil is -18° C to
+83° C.
