What Is Lubrication

Lubrication is a word that’s often used in regards to machinery reliability and maintenance, but what is lubrication? The dictionary defines lubrication as the application of some oily or greasy substance in order to diminish friction. Although this is a valid definition, it fails to realize all that lubrication actually achieves.

Many different substances can be used to lubricate a surface. Oil and grease are the most common. Grease is composed of oil and a thickening agent to obtain its consistency, while the oil is what actually lubricates. Oils can be synthetic, vegetable or mineral-based as well as a combination of these. The application determines which oil, commonly referred to as the base oil, should be used. In extreme conditions, synthetic oils can be beneficial. Where the environment is of concern, vegetable base oils may be utilized.

Lubricants containing oil have additives that enhance, add or suppress properties within the base oil. The amount of additives depends on the type of oil and the application for which it will be used. For instance, engine oil might have a dispersant added. A dispersant keeps insoluble matter conglomerated together to be removed by the filter upon circulation. In environments that undergo extremes in temperature, from cold to hot, a viscosity index (VI) improver may be added. These additives are long organic molecules that stay bunched together in cold conditions and unravel in hotter environments. This process changes the oil’s viscosity and allows it to flow better in cold conditions while still maintaining its high-temperature properties. The only problem with additives is that they can be depleted, and in order to restore them back to sufficient levels, generally the oil volume must be replaced.

Types of OilReducing friction is a key objective of lubrication, but there are many other benefits of this process. Lubricating films can help prevent corrosion by protecting the surface from water and other corrosive substances. In addition, they play an important role in controlling contamination within systems. The lubricant works as a conduit in which it transports contaminants to filters to be removed. These fluids also aid in temperature control by absorbing heat from surfaces and transferring it to a point of lower temperature where it can be dissipated.

There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear.

Full-film lubrication can be broken down into two forms: hydrodynamic and elastohydrodynamic. Hydrodynamic lubrication occurs when two surfaces in sliding motion (relative to each other) are fully separated by a film of fluid. Elastohydrodynamic lubrication is similar but occurs when the surfaces are in a rolling motion (relative to each other). The film layer in elastohydrodynamic conditions is much thinner than that of hydrodynamic lubrication, and the pressure on the film is greater. It is called elastohydrodynamic because the film elastically deforms the rolling surface to lubricate it.

Stored Equipment Needs Protection – Engine Fogging Oil

FREE Amsoil Catalog

Engine Fogging Oil

As fall turns to winter, customers in many parts of the country begin placing summer work and recreational equipment; including motorcycles, boats, lawnmowers, construction and farm equipment; into winter storage. Ensure customers’ stored equipment is protected throughout the winter season and in top condition when it is put back into service in the spring. Engine fogging oil helps protect your equipment.

AMSOIL Engine Fogging Oil

amsoil engine fogging oil

amsoil engine fogging oil

Fluctuations in ambient temperatures can cause water vapor to form condensate within stored engines. When this condensate comes into direct contact with steel
and iron components, it forms surface corrosion on cylinder liners, piston rings, anti-friction bearings and steel/
iron contact surfaces on rotational seals. Long periods of storage can also dry out cylinders, often resulting in permanent damage when the equipment is taken out
of storage and dry-started. Most two- and four-stroke motor oils are formulated to have an affinity to engine component surfaces, acting as a barrier that keeps condensate from contacting engine components and forming corrosion.
However, the effectiveness of motor oil in this area diminishes with time.

 

AMSOIL Engine Fogging Oil (FOG)

offers superior film retention, providing long-term
protection against corrosion and dry starts, etending engine life and reducing operating expenses. Amsoil engine fogging oil is an aerosol spray formulation offers easy and clean application, while
reaching more components and offering complete distribution of the oil, something especially beneficial in applications with horizontal cylinder orientation, such as outboard
motors. Consult equipment owner’s manual for application directions.

AMSOIL Gasoline Stabilizer

Gasoline is not formulated for long-term storage and can start to degrade in as little as 60 days, leading to varnish and sludge deposits that clog injectors, fuel lines and carburetors; stick oats; and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life. It is difficult to drain all of the fuel from equipment before storage, and doing so would expose the to other problems, including the formation
of rust and corrosion on the bare metal in the tank and fuel system and the drying and cracking of gaskets and seals.
Some fuels are pre-treated with oxidation inhibitors that allow them to be stored for short periods without forming excessive deposits, while other fuels have no inhibitors at all. AMSOIL Gasoline Stabilizer (AST) reduces
the oxidation that occurs when fuel is stored for extended periods, improving performance, extending equipment life
and decreasing maintenance expenses.

Amsoil Dominator

Super Film Strength

High-performance two-cycle motors have high compression ratios, which significantly increases combustion chamber heat and crankshaft bearing . Hot combustion processes quickly burn off and evaporate light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances. This promotes piston scuffing and possible seizure, and increased pressure on crankshaft bearings promotes metal-to-metal contact, wear and pitting. High heat and pressures require tough oil with better fi lm strength and more lubricity.

Amsoil DOMINATOR, constructed with AMSOIL heavy synthetic oil, handles high heat better
than mineral oils and provides improved fi lm strength and lubricity. DOMINATOR
reduces friction and provides an extra measure of protection against piston scuffing
and crankshaft bearing wear.
