Equipment Playbooks
Fluid strategies tailored to mechanical demands of specific heavy-duty assets.
Excavators
Long hydraulic duty and abrasive pins demand fluids that vent air quickly. AW 46/68 pairs well with EP2 MoS₂ grease for high impact loads.
Wheel Loaders
Torque spikes and dust call for TO-4 50 for consistent clutch friction and GL-5 85W-140 in hot final drives.
Cranes
Precise control is paramount. High-demulsibility AW 46/68 ensures valves respond consistently from dawn to dusk.
Concrete Mixers
High contamination risk. PAO-fortified GL-5 oils and high-adhesion greases resist wash-off and lower temps.
