Beneficial Qualities

N/A Long-Lasting, Cost-Saving Service
  • Provides longer service life than other commercial hydraulic oils
  • Extends drain intervals when properly maintained
  • Reduces oil consumption, including need for make-up oil
  • Minimizes labor and downtime required for oil changes
  • Eliminates fade and chatter by breaking up foam
High Viscosity Index Formula
  • Ensures smooth, uninterrupted power flow over wide temperature range
  • Increases energy efficiency, which also reduces greenhouse gas emissions
Wear Protection
  • Protects metal components from scuffing, galling and other wear
  • Minimizes equipment downtime and failure
  • Is compatible with most seals and hoses
  • Reduces need for replacement parts and labor
Water, Rust, Corrosion & Oxidation Resistance
  • Separates rapidly from water, allowing for easy water drain-off
  • Prevents rust and corrosion with R & O inhibitors
  • Provides superior oxidation resistance
    • Reduces sludge and varnish formation
    • Prevents plugged orifices and sticky valveso Maintains system cleanliness

Proprietary Additive


LE’s proprietary additives areused exclusively in LE lubricants.Equipower™ Ultra HVI HydraulicOil contains Monolec.

Monolec® wear-reducing additivecreates a single molecularlubricating film on metal surfaces,vastly increasing oil film strengthwithout affecting clearances. Aninvaluable component in LE’sengine oils, industrial oils andmany of its other lubricants,Monolec allows opposing surfacesto slide by one another, greatlyreducing friction, heat and wear.
