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.

Amsoil Equipped Motorcycles Shine In Fuel Economy Challenge

Amsoil

AMSOIL synthetic lubricants figured prominently in the Vetter Fuel Economy Challenge held May 13 in northern California, where a diesel-powered motorcycle using Amsoil products won by achieving 128.24 mpg. Many of the other bikes also relied on Amsoil products to help achieve results nearly as impressive.

Amsoil

Winning driver Fred Hayes of Hayes Diversified Technologies (Hayes-DT) completed the challenge riding the company’s MD670 F2 diesel-powered motorcycle (pictured above). Hayes bested the next closest competitor by over 18mpg using biodiesel fuel, a lightweight motorcycle design (370 pounds dry) and Amsoil synthetic lubricants throughout.

  • Engine and Transmission – Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil
  • Cooling System – Antifreeze and Engine Coolant, Dominator© Coolant Boost
  • Chassis – Series 2000 Synthetic Racing Grease
  • Chain – MP Heavy Duty Metal Protector
  • Forks – Shock Therapy© Suspension Fluid #10 Medium
  • Fuel – Diesel Concentrate

Competitors completed a 133.5-mile course designed to provide real-world, challenging conditions. The trip, beginning and ending in Carmel, Calif.,

included mountainous terrain cresting a 2,500-foot pass, while the return ride along the famous El Camino Real subjected riders to 30 mph headwinds that tested the limits of each motorcycle’s fuel efficiency. Held at various places throughout the country, the Vetter Fuel Economy Challenge dates to 1980 and aims to encourage development of motorcycle technologies that improve fuel economy while remaining viable for everyday drivers.

The winner must consume the least amount of fuel measured in dollars and cents while meeting all prescribed conditions. Hayes used $4.53 in biodiesel, essentially one gallon, to travel the entire 133.5 miles in challenging conditions, highlighting the bike’s impressive technology and the effectiveness of AMSOIL products. Hayes said his bike showed measurable improvements running Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil and Diesel Concentrate, including easier shifting from the transmission. Competitors had to remain ahead of trailing official at all times to prevent them from padding fuel economy statistics by driving slowly. Two bikes were disqualified for doing so.

AMSOIL-sponsored Hayes-DT focuses on developing the world’s most cutting-edge, heavy-fuel-powered, light tactical vehicles and small engines for military use.

In fact, key Hayes-DT corporate personnel have served in modern military conflicts deployed on Hayes-DT military motorcycles. The bikes receive the most use from the Combat Military Police for rout recognizance and convoy control.

Hayes-DT Street Fighter bike

The Hayes-DT Street Fighter bike achieved 90.82 mpg running biodiesel and AMSOIL lubricants throughout

A second Hayes-DT bike, the Street Fighter, was disqualified after a battery problem caused it to miss the official start. Following repairs, driver Josh Chen rallied to complete the course anyway, achieving 90.82 mpg, which would have been good enough for third place. The Street Fighter used the same lineup of AMSOIL products as the MD670 F2. Although neither motorcycle is available to the general public yet, Hayes-DT is currently working on EPA and EU emissions certification. Until then, competitions like the Vetter Fuel Economy Challenger allow Hayes-DT to showcase the advanced technologies of their bikes and the performance benefits of AMSOIL synthetic lubricants and additives.

Amsoil assembly lube

Amsoil assembly lube

New AMSOIL Engine Assembly Lube (EAL) is formulated to cling to engine parts and provide exceptional wear protection while inhibiting rust and corrosion in newly built or rebuilt four-stroke engines. It is designed to dissolve in oil, helping eliminate oil port clogging and deposit formation, and represents a premium option for performance enthusiasts, engine builders and race teams. It also presents a perfect complement to AMSOIL Break-In Oil (BRK), Dominator® Racing Oil (RD20, RD30, RD50) and Z-ROD™ Motor Oil (ZRT, ZRF).

 

Clings Tenaciously to Parts
Because building an engine can take from a few days to many months, using an engine assembly lube that clings well to parts for extended periods is critical. AMSOIL Engine Assembly Lube is formulated with a high-viscosity base oil and a unique tackifier for long-lasting, tenacious cling.

Exceptional Wear Protection
During initial startup, engines operate momentarily with little-to-no oil pressure, placing camshaft lobes, lifters, rocker arms, bearings and other critical parts at high risk of wear and failure. In addition to inhibiting wear by clinging to parts, AMSOIL Engine Assembly Lube contains high levels of antiwear additives for further protection.

Inhibits Rust and Corrosion
An engine can sit in a garage partially assembled for long periods, allowing moisture and oxygen to form rust on exposed metal surfaces. Amsoil assembly lube contains rust and corrosion inhibitors that protect engine components during inactivity.

Dissolves in Oil
Grease-based assembly lubes can increase the risk of oil port clogging if the grease is not fully consumed at initial startup, potentially causing engine failure. AMSOIL Engine Assembly Lube is designed to dissolve in oil, helping oil ports remain clean, and helping to eliminate deposit formation under the valve covers and in the oil pan.

Easy and Precise Application
Amsoil assembly lube is packaged in convenient 4-oz. tubes, allowing for cleaner, more precise application compared to other products.

TODAY’S TIP

Protecting Bearings From Corrosion

In a humid environment, condensate can form in rolling element

bearings and cause corrosion, leading to a reduction of the

bearing life. The condensed moisture's effect can be reduced by

carefully choosing the grease lubricant. Greases thickened with

sodium soap will absorb (emulsify) large quantities of water,

but may, however, soften it to such an extent that the grease

flows out of the bearing.

Lithium soap greases do not emulsify water, but with suitable

additives can provide good protection against corrosion. There

are also a number of greases available containing synthetic

thickeners that offer excellent protection against corrosion,

prolonging the bearing life.
