Hydraulic Oil
NOTE: Hydraulic oils require anti-wear qualities at least API Ser-
vice Classification GL-3, and sufficient chemical stability
for mobile hydraulic system service.
NOTE: Machines may be equipped with Mobil EAL biodegrad-
able and non-toxic hydraulic oil. This is a fully synthetic
hydraulic oil that possesses the same anti-wear and rust
protection characteristics as mineral oils, but will not
adversely affect the ground water or the environment
when spilled or leaked in small amounts.
