AMSOIL recently completed a comprehensive study of gear lubricants that will undoubtedly shake up the marketplace. Fourteen of the most popular brands of gear lube were tested at an independent laboratory in areas such as pour point, 4-ball EP weld point, 4-ball EP load-wear index, Falex extreme pressure and many other tests used in meeting API GL-5 performance requirements and SAE J306 viscosity requirements.
The purpose of the new Gear Oil White Paper is to inform consumers about the increasingly severe conditions under which differentials operate and to provide data reflecting the quality and cost differences of many popular synthetic and petroleum gear lubes. With this information, consumers are better prepared to make informed decisions when purchasing gear lubricants. All performance testing was conducted by an independent laboratory. Physical-property testing (viscosity, viscosity index, pour point and foaming after oxidation) was conducted in-house. Gear lube pricing was obtained from the manufacturers or distributors.
This no-frills study is designed to help consumers make informed decisions when selecting gear oils. There is no hype and no sales pitch -- just facts. Never before has so much information on gear oils been delivered in one easy to understand source.
