The purpose of the 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.

The second edition of the AMSOIL "Study of Motorcycle Oils" is now available. See how 32 of the top selling motorcycle oils compare in the most critical areas of motorcycle performance. This no-frills study was designed to help consumers make informed decisions when selecting motorcycle oils. There is no hype, no sales pitch, just facts. Never before has so much information on motorcycle oils been delivered in one easy-to-understand source.
High quality gear oils must lubricate, cool and protect geared systems. They must also carry damaging wear debris away from contact zones and muffle the sound of gear operation. Commonly used in differential gears and standard transmission applications in commercial and passenger vehicles, as well as a variety of industrial machinery, gear oils must offer extreme temperature and pressure protection in order to prevent wear, pitting, spalling, scoring, scuffing and other types of damage that result in equipment failure and downtime. Protection against oxidation, thermal degradation, rust, copper corrosion and foaming is also important.
AMSOIL Synthetic 10W-30 Motor Oil (ATM) and 10 competing conventional, synthetic and synthetic blend
10W-30 motor oils were subjected to a series of motor oil tests. The competing oils included petroleum-based
Castrol GTX, Chevron Supreme, Havoline, Formula Shell and Pennzoil, as well as synthetic-blends Trop Artic
and Motorcraft, and full-synthetic Pennzoil Platinum, Quaker State Advanced Full Synthetic and Mobil 1
Extended Performance.
The Sequence IIIF test is a stringent API SL, ILSAC GF-3 test designed to measure oil thickening and piston deposits in high temperature service, as well as provide information on valve train wear. The test is designed to emulate high-speed service under high ambient conditions.

A great deal of emphasis is placed on the importance of using of the most advanced high-quality lubricants, but superior filtration is often taken for granted. The general attitude displayed by many consumers is to use whatever is cheapest, even when they’ve invested in superior lubrication. While AMSOIL synthetic motor oils provide unbeatable protection, performance and economy, they require the assistance of filtration. Without filtration, by-products from the combustion process and abrasive materials ingested from the air will ultimately destroy an engine.
With the help of Jeff Foster Trucking Inc. of Superior, WI, AMSOIL put its Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD), as well as its Dual-Gard filtration system, to the test.
To show the superior performance of AMSOIL Synthetic Automatic Transmission Fluid (ATF) in extreme operating conditions and over extended drain intervals, an independent laboratory subjected both AMSOIL Synthetic ATF and Texaco Havoline petroleum ATF...
AMSOIL was the first motor oil company in North America to use the NOACK volatility test to measure motor oil quality and performance. Although competing motor oil companies initially paid no attention to NOACK results, the test has since become a critical measurement tool throughout the industry.
The extreme pressures and temperatures generated by modern vehicles increase stress on gear lubricants and can lead to a serious condition known as thermal runaway.As heat continues to spiral upward, viscosity continues to spiral downward. Thermal runaway is a vicious cycle that leads to irreparable equipment damage from extreme wear, and ultimately catastrophic gear and bearing failure.
