Lubrico Gear Oil GL-4 Fully Synthetic

Lubrico Gear Oil GL-5 Fully Synthetic Multi-purpose transmission oil for synchronized and non-synchronized manual transmissions and for axle transmissions, transfer cases, intermediate gear boxes, ancillary transmissions in vehicles and work machines. Synthetic GL-5 is developed to eliminate seasonal transmission oil changes. It can be used during winter and summer. The balanced additive combination warrants properties such as high pressure capacity, above average viscosity-temperature properties, high oxidation stability, low solidification points, good wear protection and prevents sludge.


  • Gearboxes requiring API GL-5 performance
  • Not intended for automatic, manual, or semi automatic transmissions for which engine oil or automatic transmission
  • Please verify OEM requirements and oil selection criteria

Features & Benefits:

  • Optimal cold flow property
  • High pressure stable lubrication film, thus outstanding wear protection under any stress, reduced transmission noise and the best transmission efficiency under full load i.e. even with very hot oil
  • Outstanding shearing stability
  • Excellent oxidation stability, no foaming
  • No oil thickening or deposits
  • Extraordinary ageing stability
  • Excellent viscosity-temperature properties
  • Effective wear protection
  • Extraordinary corrosion protection, no rust, won’t harm non-ferrous metals.
  • Neutral to sealants, i.e. transmissions stay tight, no oil loss
