Motor oil

Dispersingagents, such as polyethylene polyamide succinimides or methacrylate-type copolymers, are added to motor oils to disperse low-temperature sludge formed in spark-ignition engines. 

The classification of motor oils has not been completed in the ISO standard because the technical differences between motors in different parts of the world, particularly Europe and the United States, make the implementation of a single system of classification and specifications very difficult. In practice, different systems coming from national or international organizations are used. The best known is the SAE viscosity classification from the Society of Automotive Engineers, developed in the United States. 

The properties sought for these products depend on the type of application it is useful to distinguish motor oil from industrial lubricants.

Oil field uses are primarily imidazolines for surfactant and corrosion inhibition (see Petroleum). Besides the lubrication market for metal salts, the miscellaneous market is comprised of free acids used ia concrete additives, motor oil lubricants, and asphalt-paving applications (47) (see Asphalt Lubrication AND lubricants). Naphthenic acid has also been studied ia ore flotation for recovery of rare-earth metals (48) (see Flotation Lanthanides).

The presence of polysulfonates in petroleum sulfonates used in lube formulations has a destabilizing effect on the formulation stabiUty and function of the sulfonate in motor oils, etc. Special techniques are utilized to help reduce the carryover of residual sludge components, including the use of hydrocarbon solvents such as hexane or heptane to faciUtate separation of sludge, often with centrihigation. Other desludging procedures include water wash, H2SO4 wash, clay percolation, and filtration. 

These problems can be dealt with by usiag artificial test cloths impregnated with various approximations of natural soils such as vacuum cleaner dust, dirt from air conditioner filters, clays, carbon black, fatty acids, dirty motor oil, and artificial sebum, either alone or ia combination (37,94—98). The soils are appHed by sprayiag, immersion, or padding. If the soils are carefully appHed, reproducible results can be obtained. Soil test cloths can be of great help ia detergency studies, when used with an understanding of their limitations. 

Other carbonaceous materials such as municipal waste plastics, cel-hilosics, and used motor oils may also serve as cofeedstocKs with coal in this technology. 

The homopolymer finds a variety of uses, as an adhesive component, as a base for chewing gum, in caulking compounds, as a tackifier for greases, in tank linings, as a motor oil additive to provide suitable viscosity characteristics and to improve the environmental stress-cracking resistance of polyethylene. It has been incorporated in quantities of up to 30% in high-density polyethylene to improve the impact strength of heavy duty sacks. 

Heavier Fuel Oils and Lubricating Oils Low volatility distillates, e.g., motor oil. Asphalts and Tars Lowest volatility and generally a smelly, sticky mess filled with impurities. 

You do not need to report items that make up the structure of your facility, such as walls any flooring, installation, or wiring. Also, you do not need to report the furnishings in your facility, such as desks, chairs, carpets, and draperies. When completing the survey you do not have to make employees account for their personal possessions, such as matches. If the facility owns and operates a number of vehicles, do not report the gasoline, motor oil, etc. in those vehicles. However, you must report the gas tank you have on site for fueling vehicles, and the motor oil and other reportable supplies you might keep on hand for maintenance. 

Cutting oil, motor oil, lubricating oil or transmission fluid should be reported as petroleum oil. 

Chemical Designations - Synonyms Crankcase oil Motor oil Transmission oil Chemical Eormula Not applicable. 

Observable Characteristics - Physical State (as shipped) Liquid Color Yellowish Odor Like motor oil. 

Picarmite. A plastic military Dynamite, developed at PicArsn about 1949, contg 70 RDX, 15 talc, 9 di(2-ethylhexyl) sebacate, 3 polyiso-butyiene, and 3% SAE 10 motor oil. it had a wt strength equivalent to 47% straight Dyna-... 

Crude petroleum is refined to produce a variety of useful products. Shown are motor oil and lubricant jelly. 

Appearance Oily liquid that is clear, and tasteless. It is amber colored similar in appearance to motor oil. 

Exposures to hydraulic fluids occur mainly in workers using hydraulic equipment and in people who work on cars or tractors that use the fluids. Most people are exposed when fluids spill or leak on the skin, when the fluid is changed, or when the fluid reservoirs are filled. Low levels of hydraulic fluids may occur in the air near machines that use them. Understanding environmental levels of hydraulic fluids is very difficult because the ingredients in hydraulic fluids are used in many products other than hydraulic fluids. For example, mineral oil is an ingredient in both motor oil and mineral oil hydraulic fluids. In the environment, mineral oil from both sources would appear to be the same. Polyalphaolefin hydraulic fluids have chemical components and potential applications similar to mineral oil hydraulic fluids.
