AMSOIL Introduces Its New Line of Synthetic Gear Lubes

The automotive industry is not static. With technology constantly improving, vehicle and engine designs change. Today’s vehicle line-up is vastly different than it was 10 years ago, with SUVs and trucks representing the fastest growing segment of the U.S. automotive market. In addition, the industry is moving away from front wheel drive vehicles, and rear wheel drive vehicles are making a strong comeback. The rapidly changing and diversifying vehicle market requires new and improved gear lubricants.

What has changed?
Modern vehicles are designed with more horsepower and torque than in years past, allowing them to haul and tow heavier and heavier loads. This results in higher gear loading and hotter running differentials. In addition, factors such as increased interior space and lower floor boards push axles higher into the vehicle’s body, reducing air flow and increasing heat. The closer proximity of the axles to the exhaust system also effectively raises heat, while more aerodynamic body styles and air dams result in restricted air flow to the differentials.

A number of factors cause SUV, pickup truck and van gears to operate under more severe conditions than over-the-road trucks, contributing to increased temperatures, higher gear loading and shorter drain intervals. First, these vehicles have smaller gears that must handle higher loads per square inch of surface area. Second, their smaller sump sizes (and lower volume of gear lube) cannot dissipate heat as well as larger sump sizes. Third, air flow is significantly reduced compared to over-the-road trucks. Fourth, these vehicles are subject to more frequent stop and go driving conditions and are more susceptible to moisture from condensation due to varying temperature fluctuations.

The AMSOIL Solution
In order to optimize its gear lubes for modern applications, AMSOIL has updated its gear lube formulations.

SEVERE GEAR™ Synthetic Extreme Pressure Gear Lubes (75W-90 & 75W-140)
Specially formulated for severe duty applications, AMSOIL SEVERE GEAR™ Synthetic Extreme Pressure Gear Lubes are excellent for vehicles that experience towing, hauling, steep hill driving, commercial use, racing, off-road use, rapid acceleration, stop and go driving and high ambient temperatures. AMSOIL SEVERE GEAR™ Gear Lubes are formulated with increased levels of premium quality additives, allowing improved limited-slip and locking differential performance. And with high viscosity indices, SEVERE GEAR™ Gear Lubes provide an extra level of protection at high temperatures. Extra additives provide additional insurance against wear in case of a lubricant film breach. These additives provide an iron sulfide barrier coating that effectively prevents micro-welding that leads to heat and friction. This allows AMSOIL SEVERE GEAR™ Gear Lubes to prevent thermal runaway, a phenomenon caused by a lubricant’s inability to control  friction and increased heat under high-stress conditions. By preventing thermal runaway, AMSOIL SEVERE GEAR™ Gear Lubes inhibit component damage and rapid lubricant degradation.

(SVG) Severe Gear™ Synthetic Extreme Pressure (EP) 75W-90 Lubricant  replaces Series 2000 Synthetic 75W-90 Gear Lube (TGR).

SEVERE GEAR® Synthetic Extreme Pressure (EP) Lubricant 75W-110 (SVT)

(SVO) Severe Gear™ Synthetic Extreme Pressure (EP) 75W-140 Lubricant replaces Series 2000 Synthetic 75W-140 Gear Lube (TGO).

Long Life Synthetic Gear Lubes (75W-90 & 80W-140)

AMSOIL Long Life Synthetic Gear Lubes are formulated with new and enhanced additives designed specifically for extended drain intervals of up to 500,000 miles in over-the-road trucks. Long Life Synthetic Gear Lubes are engineered to protect gears better than conventional gear oils, resisting acid, carbon and varnish formation and oxidative breakdown. Their superior shear stability allow them to maintain their viscosity during extended service. The enhanced 80W-140 formulation replaces the former 85W-140 formulation, allowing a greater operating range and improved cold temperature performance.

AMSOIL Long Life Synthetic Gear Lubes are available in five gallon buckets, excellent for use with lube dispensing pumps.

(FGR) Long Life Synthetic 75W-90 Gear Lube replaces Synthetic 75W-90 Gear Lube (AGR).

(FGO) Long Life Synthetic 80W-140 Gear Lube replaces Synthetic 85W-140 Gear Lube (AGO).

(AGL) SAE 80W-90 Synthetic Gear Lube

The (AGL) SAE 80W-90 Synthetic Gear Lube market is mineral oil based. New reformulated AMSOIL 80W-90 Synthetic Gear Lube is designed as a high quality synthetic replacement for mineral gear oils. It is a multifunctional product designed to surpass the requirements of equipment and automotive applications calling for an SAE 80W-90 viscosity grade. Its naturally high viscosity index and shear stable construction provide improved cold temperature performance, while extreme pressure additives provide excellent protection for gears and bearings. AMSOIL 80W-90 Synthetic Gear Lube is competitively priced, making it an excellent choice for cost conscious customers.

Existing Synthetic Gear Lube and Series 2000 Synthetic Gear Lube formulations will remain available while supplies last.

AMSOIL has optimized gear lube performance for specific operating conditions. However, AMSOIL gear lubes are multi-functional and may be used in many different applications. This chart conveys the best AMSOIL recommendation based on product design and operating environment.

First row product recommendations offer superior performance in the respective applications. Second row product recommendations offer excellent performance in the respective applications. The third row is exclusive to SAE 80W-90 viscosity.

AMSOIL Severe Gear® 75W-90 (SVG), 75W-110 (SVT) and 75W-140 (SVO) synthetic gear lubes have a performance emphasis on the extreme pressure and high heat of today’s vehicle differentials.

AMSOIL Long Life 75W-90 (FGR) and 80W-140 (FGO) synthetic gear lubes have a performance emphasis on 500,000 mile extended drain intervals associated with larger sumps and lower operating temperatures of over-the-road truck differentials.

AMSOIL 75W-90 synthetic gear lubes will outperform conventional 80W-90 gear oils in all applications and may be used as a replacement.AMSOIL offers 80W-90 (AGL) synthetic gear lube for those customers requiring this specific viscosity grade.
