Gear Oil GL-4 is 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 Gear Oil GL-4 makes it 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.
