GEAR OILS

PROTECTION UNDER PRESSURE

⚙️

Extreme Pressure (EP)

EP additives form a protective layer on gear teeth to resist wear, scoring and pitting under heavy load.

🔇

Smooth, Quiet Gears

Stable viscosity keeps gearboxes and differentials running smoothly and reduces gear noise.

🧲

Corrosion Protection

Protects bearings and gear surfaces against rust and corrosion between services.

GL-4 VS GL-5 — WHICH GEAR OIL?

Check your vehicle manual for both the API GL level and the viscosity grade.

API GL-4

Moderate EP protection for manual gearboxes and transmissions, including those with yellow-metal (brass) synchronisers. GEAR GUARD EP-90.

API GL-5

Higher EP protection for hypoid differentials and heavily loaded axles. GEAR GUARD EP-140 and GEAR PRO+.

90 vs 140

80W-90 / EP-90 suits most gearboxes and differentials; 85W-140 / EP-140 is thicker for heavy loads and hot running.
