API (American Petroleum Institute) Service Classification: defining the performance of an engine oil service classification. API is determined by the engines of different types of oils tested. Part abrasions and similar criteria, taking into account oils are classified. As of 2000, CH-4 gasoline engines, diesel engines, the upper classes of the SJ-service classes.

Aromatics (aromatic hydrocarbons) with high density and good solubility characteristics hydrocarbon group. "Aromatic" is defined as. Because many are sweet and aromatic odor. Typical examples are benzene, toluene and xylene.

Acid value (Number): the amount of KOH required to neutralize a petroleum product. In addition, also referred to as neutralization value. Unit "mg.KOH / g.oil" shape.

Extreme pressure (EP) lubricants: EP oils and greases under the effects of high temperature and pressure, of metal surfaces, a protective film-forming additives (usually sulfur, phosphorus or chlorine-based) contain. In this way, the high-pressure metal-to-metal contact and did not tear under normal hydrodynamic film is.

Base stock (base oil): Oils and other products used in the manufacture of refined petroleum oil. The base oil is used alone, as well as other base and / or additives in the blend.

Multi-grade (multigrade) is a term used to describe the properties of the oil temperature and viscosity. This class of low and high temperature viscosity of the oils, corresponds to the limits of two different SAE numbers.

Distributor additives: additives detergent wash all the dirt is solved, solid and wear metal particles floating in oil, keeping the condition of the engine interior surfaces, oil drain, gaydlarına valve, piston ring sticking to their slots in the pan crashes, combined with each other prevents them from large parts of the filter until the carry.

Dropping point: The specified test method is fluent in airborne grease with the lowest temperature.

Detergent: the ability to keep the oil clean the surfaces of the equipment running. This task, insoluble substances by preventing accumulation of suspended perform and hold.

Detergent additive: high temperature prevents the build-up of deposits that may occur and the machine is running under the oils additive components that solve the accumulated deposits.

Freezing point depressants: Very cold weather, the run-time engine oil additive which allows you to maintain fluidity.

Emulsion: miscible or immiscible with each other to mix two liquids formed. One of the many fat emulsion with the other ingredients in water or water-based wt.

Grease: a thickener consisting of the mixture with the lubricant fluid, semi-fluid consistency ranging from a solid material. The purpose of lubrication with oil and grease are the same. For this purpose the minimum level of friction and wear between moving surfaces to download.

IP: Petroleum Institute (Institute of Petroleum)

ISO: International Organization for Standardization.

Additive: Mineral oils used in the production rate of approximately 10-15 per cent, oil cleaner, rust inhibitor, coloring, preservatives, thickeners, viscosity index improver, anti-wear, oxidation protection, pour point depressants, anti-foaming properties added in order to give Substances to be described as additive.

Slider additives: additives developed in order to increase the oil slider feature, irreducible power losses caused by friction, ie to increase the efficiency of the engine works.

Corrosion of metal by chemical or electrochemical reactions influenced by the surrounding corruption.

Corrosion Inhibitor: the deterioration of the products of combustion of oil or corrosion protection agent occurring substances.

Antifoam: Oil a very small amount of oil present and as a result of contact with air to prevent foaming agent.

Ash content: under the conditions specified by the reaction of remaining waste oil with sulfuric acid. A metal-based oil is used as a measure of the amount of organic chemicals.

Lak: pistons and cylinders of internal combustion engines of the "fat-soluble" deposits. Exposed to high temperatures released by the oxidation of oils and fuels interests. Similar to waxing but tough.

Program (mineral) oil: Mineral oil derived from petroleum sources, in particular.

Molybdenum di sulphide (solid lubricants): Chemical structure conceived, depending on the chemical composition is capable of lubrication, even at very high temperatures.
Multigrade (four seasons) fat: with just a number (number 30, number 40, etc.) can serve in a temperature range wider than the oil engine or gear oil. Multigrade oils from one of the other classifications that at high temperatures there are two separate numbers. (20W-50, 15W-40, etc.).

Oxidation: oxygen, with a substance (for example, oil), combined with another material (e.g. lacquer) to create. As a result of this process, oxidation products, and generally takes place under the thermal conditions.

Oxidation inhibitor additives: oil, hot air is oxidized by oxygen in the air multiplied by. Slowing down this process extends the life of the oil additives and protecting against oxidation by coating the metal surfaces.

Octane number: gasoline, engine speeds not to knock When a numeric value indicating the properties. A fuel octane number, it depends on the hydrocarbon composition. Additional additives, octane number can be increased.

Flash point: Defined a test apparatus, air mixed with combustion product produced by the mixture at the lowest temperature point of a shine. Open and closed as measured by two separate calls. Gives an idea about the volatility of petroleum products.

SAE: SAE oil containers encounter different temperatures in order to classify oils according to the habits of Automotive Engineers' Association (Society of Automotive Engineers) is an acronym developed by. SAE 0W gauge from the SAE 60 extends up. SAE 0W, 5W, 10W, 15W, 20W, 25W, Cold climates are classified with the maximum allowable viscosity. SAE 20, 30, 40, 50, 60; engine operating temperature of 100 ° C the viscosity measurements are classified according to.

Synthetic oil: oil obtained by synthesis. Many of these oils at high temperature stability and has the advantages of unlimited in terms of fluidity at low temperatures. However, more costly than mineral oils.

Cold Mud: The engine is a result of long exposure to low temperature conditions, by oil and oil accumulated in the insoluble substances.

One grade: Oils SAE viscosity number one fell between the limits of the time, oil is a term used to describe.

Total base number (TBN): 1 g 'health all the basic components present in the sample the amount of acid required for neutralization, in units of milli-equivalent in terms of number of equivalent expression.

Viscosity: Viscosity feature. Often refers to the status of the high viscosity.

Viscosity: The resistance of the oil viscosity is called fluidity. The aim of the oil is flowing cold enough, to ensure that the heat is more thick.

Viscosity index: a scale used to measure the variation of the temperature of a liquid viscosity.

Fat: sürtünmekte in order to reduce friction between the surfaces of any article which can be administered.

Load carrying capacity: An oil film of high pressure, high temperature and resistance to tearing under high speed.

High-pressure additives: two floating gears and bearings operating under very high pressure very close to the surface in contact with the metal surface protective film-forming additive chemical reaction.
