Vegetable oils also have a very high viscosity index (VI). Synthetic fluids are real problem solvers—and very important in improving equipment reliability. Note that this is a composite of all the major synthetic types. Mineral engine oil is cheaper, because no other chemicals are added. His education includes a Bachelor of Arts in English and political science from Saint Mary's College and a Master of Business Administration in finance and marketing from California State University, Sacramento. Viscosity index can be defined as a frequently used measure of a fluid’s change of viscosity with temperature. Vegetable oils can be used as lubricants in their natural forms. Studies show that much of this fluid (60 percent) is not accounted for and ends up in ground water, rivers, lakes and on the ground itself, causing untold harm to the environment, fish and wildlife. On the negative side, vegetable oils in their natural form lack sufficient oxidative stability for lubricant use. AcknowledgementsThe author wishes to thank Dr. Ken Hope, of Chevron Phillips, and Dr. Martin Greaves, of Dow Chemical, for their assistance in the preparation of this article. Synthetic oils, on the other hand, are equally effective at every moment. Such resources work well for combustion-type engines, but they have a limited availability and frequently can't be reused. Advantages/disadvantagesFig. 62% of lubrication professionals do not use any biodegradable lubricants at their plant, according to a recent survey at machinerylubrication.com. The percentage of oxygen consumption or carbon-dioxide evolution is monitored to determine the degree of biodegradability. For a test to be considered readily biodegradable, there must be more than 60-percent degradation in 28 days. The use of biodegradable fluids can help to maintain the environment and relieve some of the demand on mineral oils in the future. Within the scope of this particular article, we will deal with the most common. Low oxidative stability means the oil will oxidize rather quickly during use if untreated, becoming thick and polymerizing to a plastic-like consistency. They have several advantages and disadvantages when considered for industrial and machinery lubrication. In some cases, oil can be recycled with filtering to be used again. Then, with the natural pressure the oil is under due to earth's weight, it flows easily out of the drilled escape. Fig. This fossil fuel (a mineral developed from compressed organic matter buried for centuries underground) provides a powerful energy resource when heat is applied. Now, more and more uses are being found for these formulations and they are experiencing significantly high growth rates. Contact Josh at email@example.com.<;/p>. A 2010 study estimated the marine inputs of lubricant oils within the 4,708 ports and harbors of the world through stern tube leakage and … PAGs can be made either water soluble or insoluble. Synthetics aren’t new; they’ve been around for 70 years. Drawbacks: - Due to the high mineral content, it is less effective in high temperature or cold weather - Not refined in the highest technology 3. Oil is fairly easy to produce. Before knowing about the types of engine oil, one must first know what is engine oil? The challenge with hydrogenation is determining at what point the process should cease. The Difference Between Synthetic and Conventional Motor Oil, Advantages and Disadvantages of Commonly Used Synthetic Base Oils, Advantages/Disadvantages of Diesel Engines VS Gasoline Engines, Advantages/Disadvantages of Grease over Oil, Evaluating Grease Quality and Performance, How to Minimize Effects of Severe Service Conditions of Enclosed Gear Lubricants. This will be discussed in the next article. Here every particle is the same size, so that it can penetrate any part of the engine very well and multiply the performance and efficiency of the engine. There are 3 types of engine oils in our country1. Crude Oil: Paraffinic, Naphthenic, or Mixed Base? Depending on the required liquidity and pour point of the oil, optimum hydrogenation is established. They have several advantages and disadvantages when considered for industrial and machinery lubrication. Engine oil is also known by a few more names such as motor oil, or engine lubricant etc. Motul first introduced it in 1966. If disposed of the wrong way, oil can poison the ground and water underground. They have several advantages and disadvantages when considered for industrial and machinery lubrication. Studies show that much of this fluid (60 percent) is not accounted for and ends up in ground water, rivers, lakes and on the ground itself, causing untold harm to the environment, fish and wildlife. They have several advantages and disadvantages when considered for industrial and machinery lubrication. Semi-synthetic engine oil. There are many factors that play into grease and oil.
