Avoid Summer Breakdowns

Another summer season is underway, and with summer comes a wide variety of recreational activities such as fishing, boating, jet skiing and ATV and dirt bike riding. Many enthusiasts use trailers to tow their equipment, and in order to avoid any inconvenient and expensive breakdowns, it is crucial to ensure proper maintenance has been performed on the tow vehicle. It is especially important not to forget about the vehicle's drivetrain. Nothing will ruin a weekend quicker than becoming stranded on the side of the road.

Severe duty activities such as towing heavy trailers, hauling heavy loads and off-roading place an increased level of stress on drivetrain components. Modern vehicles such as turbo diesel trucks and vehicles with V-10 engines boast more horsepower and torque than their predecessors, but differential designs have remained virtually unchanged through the years. Differentials today are subjected to severe duty service and encounter more stress and heat than was seen only a few years ago.

Thermal RunawayThe 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 temperatures in the differential climb upward, gear lubricants lose viscosity and load carrying capacity. When extreme loads break the lubricant film, metal-to-metal contact occurs, increasing friction and heat. This increased friction and heat, in turn, results in further viscosity loss, which further increases friction and heat. As heat continues to spiral upward, viscosity continues to spiral downward. Thermal runaway is a viscous cycle that leads to irreparable equipment damage and extreme wear, and ultimately catastrophic gear and bearing failure.

Viscosity is the most important property of a lubricant in its defense against thermal runaway. Viscosity correlates to film thickness and film strength, which keep moving parts from contacting each other and creating increased friction, heat and wear. The higher the viscosity of a lubricant, the greater protection it provides. However, a lubricant which is too thick is detrimental because it consumes more energy and increases fuel consumption. The original equipment manufacturer (OEM) determines which viscosity grade is optimum for the specific application.

Many gear lubes are formulated with additives called viscosity index (VI) improvers. These additives broaden a lubricant's operating temperature range and are used to ensure multi-grade viscosity performance for hot and cold temperatures. VI improvers keep lubricants from becoming too thick to flow in cold temperatures and too thin to protect in high temperatures. However, shearing forces within equipment can cause these additives to break down and lose viscosity, seriously compromising the lubricant's protection qualities.

AMSOIL Severe Gear Synthetic Gear Lubes demonstrate superior viscosity index and shear stability properties, and they are better equipped to protect equipment against the devastating effects of thermal runaway. Severe Gear Synthetic Gear Lubes are blended with superior high VI, shear stable synthetic base oils and an overtreatment of extreme pressure additives that effectively protect high stress applications against friction, heat and wear; keep equipment in top working order and ensure summer trips aren't ruined by a broken down vehicle.

"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems. ISO standards are used by over 300,000 companies worldwide setting rigorous standards for businesses, government and industry.

ISO 9001:2000 is applicable to any manufacturing and service organization providing a framework for system development that focuses on the customer, quality system performance and ongoing improvement. AMSOIL received ISO 9001:2000 registration under the scope: synthetic lubricants blending, packaging, and other fulfillment directly associated with lubricant product.

The ISO certification puts AMSOIL in line with some of the most efficient companies in the world. It is further assurance that the products and services AMSOIL provides will continue to maintain the high level of quality the company always demanded.
