GL-1 SAE 90

GL-1 SAE 90 Gear Lubricant

STARFIRE GL-1 SAE 90 is manufactured with high quality base stocks to provide outstanding oxidation stability for long service life. This oil is inhibited against foaming and does not contribute to corrosion or wear of yellow metals, such as brass or bronze.


STARFIRE GL-1 SAE 90 is designed for use in manual transmissions and transfer cases in on-highway trucks and off-highway equipment, which require an API GL-1 gear lubricant. It is also suitable for use in industrial gear oil applications that call for a straight mineral oil in the SAE 50 engine oil viscosity weight range.


  • Long service life
  • Non-foaming
  • Non-corrosive

All STARFIRE Premium Products are available in bulk packaging - pails, kegs, drums, totes and bulk transport loads.
