Gear Oil GL-4
Automotive gear lubricants

Gear Oil GL-4 are proven performance automotive gear lubricants suitable for API GL-4 applications.
- Gear Oil GL-4 products are designed for use in automotive transmissions, transaxles, steering systems and hypoid drive axles which require a fluid with API GL-4 performance (equivalent to US Military specification MIL-L-2105).
- The friction characteristics of the Gear Oil GL-4 product range make them suitable for use in many synchronized manual transmissions.
- Some modern transmissions may require a specific fluid type – refer to the manufacturers’ literature for further details.
- Proven additive system offers reliable EP protection to critical components against scuffing and wear
- Low temperature fluidity promotes rapid oil circulation during cold start-up, helping protect system components
- Robust shear stability helps ensure viscosity is maintained throughout oil service life
