Reality: New-car and new-engine manufacturers require that an API-certified oil be used to keep a warranty intact. Since rerefined oils earn API certification, the warranty will not be voided. Myth #3: Some buyers for large fleets specify brand names rather than oil performance criteria. This is why changing the oil in you car’s engine is part of a good preventive maintenance program. The Postal Service used over , gallons of motor oil in FY , most of which was re-refined motor oil. Why use re-refined motor oil? The physical property of oil doesn’t degrade. Re-refining used motor oil relies on a practice of vacuum. If these re-refined oils are manufactured correctly, there is then no reason not to use them. We approved the use of re-refined engine oils for use in our engines decades ago. The requirement is, above all, that the re-refining process is perfect and the oils are alloyed correctly just like virgin base oils. Analyzing the oil in your car is like sending a sample of your blood to the lab — it reveals an astonishing amount of information about the inner workings of your engine without invasive surgery.

Any brand of engine oil can be used as long as it meets the _____ and API standards. viscosity Synthetic oil means that it is a _____________ product and not refined from a naturally occurring substance, as engine oil (petroleum ase) is refined from crude oil. Appropriate additive packages will be combined with the re-refined and performance will be measured with a series of engine tests. If percent re-refined oils are found to be un- qualifiable, the USAMC will test various blends of virgin oil and re-refined oil until a qualifying mixture can be specified. This blend of AeroShell Fluid 2XN and AeroShell Oil can be used in any certified aviation engine, although we don't recommend its use in 2 stroke or automotive derived engines. As mentioned, once mixed with fresh AeroShell Oil , this oil can be used as a flyaway oil. It is not only the engine that we can analyse by sampling used oil, we can also look at the condition of the oil. As oil is used in an engine several things happen to it to cause it to degrade. The best measure of the condition of the oil is what is known as the Total Acid Number, or TAN.

oil lab that assesses engine wear conditions because natural gas engine oils, TAN is monitored along with other engine oil parameters. Section 1: Introduction Figure Information provided Table 1 is a comparison of oil analysis parameters for engines and rotating machines.

Table 2 shows the physical and the chemical properties of various multigrade engine oils (20W and 15W). For samples 5 and 7, a high pour point value is observed for typical multigrade engine oil.

For samples 5 and 6, a high apparent viscosity at −15 and −20 °C is also observed (max. and cP, respectively).Cited by: Research Project Title: “Study of Re-refined Oil Use in Diesel Engines: Final Report” Abstract Because of the concern that re-refined oil was causing engine failures, a study was initiated to compare the wear effects of re-refined and virgin oils using the two Detroit Diesel engines in a ferryboat that would experience.

refined virgin base oil or as clean burning fuel.[4]. Treatment Technologies. The idea of recycling used lubricating oil was presented in the year of Initially the used lubricating oils were burnt to produce energy, and later these oils were reblended to - engine oils after treatment.

Due to the increasing necessityFile Size: KB. Vehicle and engine manufacturers such as Ford, General Motors, Chrysler, and Detroit Diesel have issued warranty statements that allow the use of re-refined oil as long as it meets API standards.

Many government and private fleets have used re-refined lubricants in their vehicles for years and report no difference in performance from virgin. Used lubricating oil is a valuable resource. However, it must be re-refined mainly due to the accumulation of physical and chemical contaminants in the oil during service.

Refining Used Lubricating Oils describes the properties of used lubricating oils and presents ways these materials can be re-refined and converted into useful lubricants as well as other products.

It provides an up-to-date. Automotive engine dynamometer tests were run at several operating conditions and showed fuel economy improvements for low viscosity oils and for oils containing friction reducing additives. Data from vehicles tested on an All Weather Chassis Dynamometer provided an excellent simulation of field service.

The laboratory test procedures correlated. Radioactive oils were run in a laboratory V8 engine to determine the effects of viscosity and volatility on oil consumption.

Using a tritium tracer method, very precise oil consumption rate measurements were consumption rates of 14 test oils, blended from two crude sources, were measure. Oils B and C are engine oils based on leading-edge technology with advanced additives in comparison with oil A.

They are selected for the demands in bio-fuelled engines and differ in their additive chemistry from each other. Fig. 3, Fig. 4 display the development of the oil parameters during the artificial ageing procedures of oils B and C.

the square of rpm, so a car engine has far more demanding lubrica-tion requirements than an airplane’s engine has. Oil also serves as a vital coolant for engine components that can’t be air-cooled. Pistons, for example, are exposed to just as much heat of combustion as cylinders, but they don’t have cooling fi ns or expo-sure to airfl ow.

searches the inventories of overbooksellers worldwide, accessing millions of books in just one simple step. Plus, re-refined oil reduces greenhouse gas emissions by up to 81 percent, according to API. Safety-Kleen’s re-refined EcoPower family of products - which are American Petroleum (API)-licensed and exceed all North American standards for engine protection - includes heavy duty diesel engine oils and synthetic blend passenger car motor oils.

The resulting product—called “rerefined” oil—must meet the same stringent refining, compounding, and performance standards as virgin oil for use in automotive, heavy-duty diesel, and other internal combustion engines, and hydraulic fluids and gear oils.

Extensive laboratory testing and field studies conclude that rerefined oil is equivalent to virgin oil—it passes all prescribed tests and, in some situations, even outperforms virgin oil.

Comparison between the pr operties of re-refined oil with the virgin, Egyptian s tan da rd [18] and used oils. Emam, A. Shoaib/Petroleum & Coal 55(3) All of these are false — particularly the one about re-refined base oils.

Chris Parent, district manager with Newalta, a product recovery company with six facilities across Canada, says this myth about re-refined base oils is one that grew out of the early days of waste oil recovery.

agencies purchase re-refined lubricating oils with at least 70 percent re-refined base stock. The EPA recommends that agencies set their minimum re-refined oil content standard at the highest level they can, but no lower than 25 percent re-refined oil.

The small price difference between re-refined and virgin oil fluctuates. Sometimes re-refined. The American Petroleum Institute (API) allows the use of re-refined base stock oils in the blending of end use lubricants.

Based on oil sample testing performed in this research as well as other authoritative sources, it was determined that no significant chemical or physical differences exist between re-refined and virgin oils. Difference between Virgin, Re-refined, and Recycled Engine Oil by Martha's Whirled News • Ap • Comments Off on Difference between Virgin, Re-refined, and Recycled Engine Oil When it comes to cars, choosing the perfect car, whether it be.

Media had a chance to watch the teardown of the two Cummins ISX diesel engines using EcoPower re-refined oil. Safety-Kleen Systems, which markets EcoPower re-refined engine oil, announced on July 25 the results of a four-year, million-mile test of the engine oil used in two Cummins ISX HP EGR diesel engines operated by Cooke Trucking Co.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A literature search to identify deleterious effects of using re-refined oil did not disclose any validated occurrences.

Significant engine testing using re-refined lubricating oil is reported and no cases were discovered in which engine operation was affected negatively by the use of re-refined oil.

Analyzing the oil in your vehicle is like sending your blood to the lab for tests. An engine oil analysis can provide clues about the health of your engine – without any invasive surgery.

By analyzing a sample of used engine oil, you can determine the amount of contamination, the wear rates and overall condition of your engine. Design Aspects of Used Lubricating Oil Re-Refining presents a feasible and comprehensive technology for recycling of used lubricating oils.

This book discusses efficient and effective ways of reusing lubricating oil which, if implemented, will result in a better quality of life, the stability of the environment, the health of national economies and better relationships between nations.

out on engine deposits, debris & fuel samples as well as the oil samples themselves. Non routine analyses typically require larger sample volumes (1 litre or so), and the analyses performed are chosen on a case by case basis with guidance from the oil supplier and / or engine manufacturer.

Use of a different laboratory may also be required. An important quality feature of a crankcase engine oil is its ability to control oil consumption.

To the average motorist low oil consumption is synonymous with the oil maintaining good engine performance, low levels of engine wear, low running costs and a clean driveway. In the current environmen. Re-Refined Motor Oil is Safe to Use. Re-refined motor oil that meets all API and OEM performance and quality requirements is safe to use in your engine, and it will NOT void your new car or powertrain warranty, and it will perform the SAME as any conventional motor oil in your engine.

Oils that do not meet EPA’s definition of used oil can still pose a threat to the environment when disposed of and could be subject to the hazardous waste regulations and management practices.

Indiana has passed regulations for the generation and handling of used oils, conveniently called the “. Average crude oils have 3–8% base-oil, whereas lube crudes typically have 12–16% base-oil. This compares with 65–75% recoverable base-oil content in used automotive oils, which if burnt or dumped would mean the loss of a valuable natural resource.

The recycled oils produced with solvent refining or hydroprocessing can be used as. This test method covers the rapid determination of 22 elements in used and unused lubricating oils and base oils, and it provides rapid screening of used oils for indications of wear.

Test times approximate a few minutes per test specimen, and detectability for most elements is in the low mg/kg range. In addition, this test method covers a wide variety of metals in virgin and re-refined.

A considerable amount of test data on re-refined aircraft-engine oils is presented in order to compare the results obtained by different re-refining units and by slight variations in the process employed by any given unit, and also to point out how a properly re-refined oil is substantially equal to the original new oil.

Ill Statements from Engine Manufacturers on the Use of Re-Refined Oils Figure 5 Comparison of Virgin and Re-Refined Oil Sample Test Results 0 to collect and test oil samples from TxDOT vehicles and compare virgin and re­ refined oils before and after.

Motor oil, engine oil, or engine lubricant is any one of various substances that consist of base oils enhanced with various additives, particularly antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index oil is used for lubrication of internal combustion main function of motor oil is to reduce friction and wear on moving parts and to.

The primary focus of US Patent No. 4, is the effectiveness of RSO as the base component of an hydraulic fluid used within a laboratory environment []; other usable triglyceride oils were olive oil, peanut and maize oil. These oily triglycerides are liquids at 15–20 °C with saturated fatty acids (SFA).One easy way to catch a glimpse of your engine’s overall health is through an oil analysis.

Most oil analyzers can test for wear metals (elements like iron, aluminum, and copper) to see if things like piston rings, pistons, bearings, or valvetrain components are breaking down.of re-refined oil contained in lubricating oils, hydrau- lic fluids, and gear oils purchased by federal, state, and local government agencies and contractors that use fed- re-refined oil [7].
