Synthetic Gear Lubes

API GL-5, MT-1, SAE 75W-90, 80W-90, 75W-140, 80W-140

AMSOIL synthetic gear lubes keep differentials and EP gear-lube equipped transmissions running clean, protected and at top-efficiency.

Load-Bearing and Extreme Pressure Protection

AMSOIL synthetic gear lubes are formulated to protect gears operating in heavily loaded conditions, whether or not the gears operate with full film lubrication. Superior film strength and viscosity retention offer superior protection in full film regimes, while top-quality extreme pressure agents protect when a full lubricating film does not separate gear surfaces.

The thermal durability of AMSOIL synthetic gear lubes ensures extreme pressure protection after extended exposure to extreme temperatures. The extreme pressure agents in conventional gear lubes sometimes lose their effectiveness after extended exposure to high temperatures, leaving gears vulnerable to metal-to-metal contact and wear.

High and Low Temperature Performance

AMSOIL synthetic gear lubes maintain their viscosity better with changes in temperature than conventional lubes, which allows them to protect over a broader temperature range.

They maintain better low temperature fluidity than conventional gear lubes, while also protecting better in higher temperatures.

Extended Drains

In commercial line haul trucks, AMSOIL FGR and FGO gear lubes may be used up to 500,000 miles. In cars, SUVs and light duty trucks AMSOIL gear lubes greatly exceed original equipment manufacturer’s petroleum gear lube drain intervals and may be used up to 50,000 miles in severe service or 100,000 miles in normal service, or according to the owner’s manual, whichever is longer.

Additional Benefits

AMSOIL synthetic gear lubes provide limited slip capability, and may be used in limited slip differentials without special additives.

AMSOIL synthetic gear lubes also provide outstanding protection against rust, which is important for stored equipment.

SEVERE GEAR Synthetic EP Gear Lubes

Specifically engineered for high demand applications, including trailer towing, heavy hauling, 4 X 4 off road driving, commercial use and racing. Superior lube film strength combined with extra additives protects gears and bearings from scoring and wear. Resists high heat and possesses excellent cold flow properties. AMSOIL SEVERE GEAR outperforms all conventional gear oils. Compatible with most limited-slip differentials.
