In 2007, AMSOIL subjected Severe Gear 75W-90 Synthetic Gear Lube and a number of competing gear lubes to a comprehensive series of industry-standard tests. While some lubes performed well in some areas and poorly in others, Severe Gear placed near the top in all performance categories. It revealed itself to be the most well-balanced formula for its time, capable of providing exceptional performance and protection in a range of applications.
The AMSOIL Gear Lube White paper is outdated and has been taken down. Please visit the AMSOIL Online Store for more information on AMSOIL Gear Lubricants.
Since then, AMSOIL gear lube technology has advanced, making an already superior product stronger. As the results show, the new additive technology allows Severe Gear to outperform the previous formulation and all of its competitors as tested in 2007. AMSOIL has raised the bar for gear lube performance even higher.
Increased Extreme-Pressure Protection
High-horsepower/high-torque applications demand lubricants with increased
extreme-pressure (EP) properties. The Falex Extreme-Pressure Test (ASTM
D-3233) is used to determine a lube’s ability to provide EP protection. As Chart
1 shows, although the previous formulation ranked in the top tier, the new technology provides an 80 percent increase in EP protection and easily outperforms all competing formulations from A Study of Automotive Gear Oils.
Increased Wear Protection
Severe applications such as towing, hauling and racing subject gear lubes to severe conditions, causing fluid film rupture in lesser lubricants. Metal-to metal contact can result, inviting rapid wear and, ultimately, gear failure. The 4-Ball Load Wear Index Test (ASTM D-2783) determines a gear lube’s anti-wear properties under heavy load. Higher values, reported as the Load Wear Index (LWI), indicate increased wear resistance. As demonstrated in Chart 2, the new formulation provides a 14 percent higher value than the previous formulation and ranks higher than all scores achieved in 2007 testing. The technology behind the entire line of Severe Gear Synthetic EP Gear Lubes also provides increased foam control, thermal and oxidative stability, limited slip differential chatter suppression and torque retention.
The best news of all, current Severe Gear Lube pricing stays the same. How about that, updated performance at the same cost.
This is why AMSOIL is “The First in Synthetics”
A little bit about AMSOIL Severe Gear Lubes:
AMSOIL SVG Severe Gear Oils
AMSOIL Severe Gear® Synthetic Extreme Pressure (EP) Lubricants are premium-grade gear oils specifically engineered for maximum performance in severe-duty applications. These state-of-the-art AMSOIL formulations feature an exclusive blend of high-viscosity, shear-stable synthetic base oils and an extra treatment of high-performance additives. AMSOIL Severe Gear Synthetic EP Lubricants maintain their viscosity for long-lasting protection against metal-to-metal contact. The proprietary AMSOIL additives form an iron-sulfide barrier coating on gear surfaces, providing the ultimate line of defense against wear, pitting and scoring. AMSOIL Severe Gear Lubricants help prevent “thermal runaway” — a phenomenon caused by a lubricant’s inability to control friction and increased heat under high-stress conditions. By controlling thermal runaway, AMSOIL Severe Gear Synthetic EP Lubricants inhibit rapid lubricant degradation and component damage. Equipment runs better and lasts longer with AMSOIL Severe Gear Synthetic EP Lubricants.
Applications
AMSOIL Severe Gear Synthetic EP Lubricants are excellent for severe applications, such as towing, hauling, steep-hill driving, commercial use, plowing, racing, off-road use, rapid acceleration, frequent stop-and-go operation and high ambient temperatures. Higher horsepower, towing and hauling capabilities of modern vehicles make turbo-diesel pick-ups, SUVs, vans and delivery/utility vehicles especially prone to severe service. Other severe-duty vehicles include light, medium and heavy-duty trucks, buses, heavy equipment, 4X4s, tow trucks, race cars, tractors, and motor homes.
