NOTE: Hydraulic oils require anti-wear qualities at least API Service
Classification GL-3, and sufficient chemical stability for mobile
hydraulic system service.
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.
