There Is More To Lubrication Than Simply Reducing Friction

A Balanced Formula Is Required For Optimum Performance In All Areas Of Lubrication.

TECH TALK
Dan Peterson, Vice President, AMSOIL Technical Development

Dan Peterson
Vice President,
Technical Development

I think most people have an idea of what lubrication is and that it is required to keep moving parts moving and prevent them from coming into contact with one another. In other words, we want the lubricant to minimize the effects of friction and protect moving parts. Friction is both a positive and negative force in our daily lives. It is essential for everyday tasks such as walking, where friction gives you the ability to create traction between yourself and the ground. It is also the principle behind the braking systems found in automobiles. Friction can also be our enemy. The heat generated as a result of friction can cause damage. In the January 2014 edition of AMSOIL Magazine, we discussed that an oil's primary function is reducing friction. It does this by creating a film between surfaces to prevent contact, thereby reducing friction. However, lubricants are frequently needed to do more than just provide a slippery film between moving surfaces in contact. They are tasked to carry out several other functions, some of which might not immediately spring to mind when you think about engine oils or other lubricants. Let's take a closer look at six not-so-obvious lubricant functions.

Transfer Energy: Because fluid lubricants are not readily compressible, they can act as an energy-transfer medium, such as in hydraulic equipment or valve lifters in an automotive engine. This key property allows lubricants to be used in heavy equipment to transfer energy from a hydraulic motor to pistons, which provide the means to actuate shovels, forklifts, and so on. Automatic transmissions are another good example; the fluid inside the torque converter creates and transfers energy to make the transmission work.

Clean: Lubricants maintain internal cleanliness by suspending contaminants within the fluid or by preventing the contaminants from adhering to components. Base oils possess a varying degree of solvency that assists in maintaining internal cleanliness. Solvency is the ability of a fluid to dissolve a solid, liquid or gas. While the solvency of the oil is important for maintaining cleanliness, detergents and dispersants play a key role. Detergents are additives that prevent contaminants from adhering to components, especially hot components such as pistons or piston rings. Dispersants are additives that keep contaminants suspended in the fluid. Dispersants act as a solvent, helping the oil maintain cleanliness and prevent sludge formation.

Cool: Lubricants are used to cool the parts of a component or machine while in operation - like a fan or air conditioner is used to cool the inside of a house. Reducing friction minimizes heat in moving parts, which lowers the overall operating temperature of the equipment. Lubricants also absorb heat from contact surface areas and transport it to a location to be safely dispersed, such as the oil sump. Heat transfer ability tends to be a trait of the base oil's thickness - lighter oils tend to transfer heat more readily.

Seal-Out Contaminants: Lubricants are used to seal components from outside contamination, like windows in a house or automobile. They can act as a dynamic seal in locations such as piston rings and cylinder contact areas to prevent contamination.

Dampen Shock: A lubricant can cushion the blow of mechanical shock, just as a shock absorber in a car dampens road vibrations and imperfections. A highly functional lubricant film can resist rupture and absorb and disperse these energy spikes over a broad contact area. When the mechanical shock to components is dampened, wear and damaging forces are minimized, extending the component's overall life.

Protect Against Corrosion: A lubricant must have the ability to prevent or minimize internal component corrosion. Lubricants accomplish this either by chemically neutralizing corrosive products or by establishing a barrier between the components and the corrosive material.

The important takeaway here is that lubricant quality is not about excelling in one performance area; rather, it's about the entire set of performance properties. This is another reason why AMSOIL synthetic lubricants provide such excellent value. In the key areas of quality, reliability and service life, AMSOIL synthetics are second to none. They not only excel in reducing friction, they provide across-the-board performance and protection in all crucial aspects of lubrication. Published, AMSOIL Magazine 08/14.

"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.
