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.

Rogue Chopper Scavenger Oil Change Kit–Test With Video

We bought a Scavenger oil change kit from Rogue Chopper. Here is our test, with video.

Amsoil synthetic motorcycle oil.

Free Amsoil catalog

Scavenger

I bought this kit last fall. I put it on with standard hand tools. Later, I bought the crimping tool so I could do installs on other bikes. If you are in the KC area, and want to install one of these, let me know and I’ll help out.

We thought this was a very high quality, well designed kit. The customer service was great. I would give this 5 stars out of 5.

Here is an explanation from the Rogue Chopper site;

“We all know changing the oil on our bikes is the most important routine maintenance we perform. So if you are going to change your oil, why not change all of it? We all change our oil by draining and refilling the oil tank and change the oil filter. But we never get the oil out of the engine. We pretend like it’s an insignificant amount or it’s not even there. Yet there is more than 24oz. left in the engine, 20% of the oiling system capacity! Upon engine start up, this old oil mixes with the fresh oil and starts the breakdown and discoloration of the fresh oil immediately.

Let’s face it – the oil filter only gets the particles out of the oil.
We must change the oil because of the chemical breakdown from high temperature and combustion gasses mixing with the oil which is what breaks down and discolors the oil. When you mix 24oz. of old oil with 96oz. of fresh oil, the breakdown of the fresh oil starts immediately. This would be like draining the oil in your car, changing the filter, and then pouring in one quart of the oil you just drained out and the new oil. Then pretend the quart of old oil you just poured in never came out and it’s insignificant.
Rogue Chopper has the fix for this problem; The Scavenger Total Oil Change System. This clever yet easy to use system effectively purges all the oil from the engine when performing an oil change. With this we get no old broken down oil mixing with new oil so our new oil stays fresh longer. It’s great if you want to switch to Synthetic oil from regular oil or the other way, but either way it’s a great product.”
