Through the course of the years which saw to the advancement of the Automobiles industry, resulting in the boom of the Lubricant sector. There has been a steady increase in Lubricants terminologies used by professionals in the industry to depict a scenario of event, define a concept or establish an argument. These terms are a must know for Lubricants users in order to fully understand the Lubricant industry.

A

Acid Number (AN) - Milligrams of KOH required in tests to neutralise all the acidic constituents present in a 1 gram sample of petroleum product. Also formerly called the Neutralisation Number, this property is often used to indicate the extent of contamination or oxidation of used oils.

Additive - Any material that is incorporated into a product at relatively low concentration to impart new properties or enhance existing properties.

Anti-foam Agent - Additive used to suppress the foaming tendency of petroleum products in service. May be a silicone oil to break up surface bubbles or a polymer to decrease the number of small entrained bubbles.

Anti-wear (AW) Agent - Additive that is active in preventing damage caused by occurrence of solid phase welding between sliding surfaces without local surface melting.

API Gravity - Arbitrary scale expressing, in degrees API, the specific gravity of liquid petroleum products.
Degrees API = 141.5 – 131.5 sp gr 60 / 60°F

API Service Classification - System of letter designations agreed on by API, SAE and ASTM to define broad classes of engine service. Also a system of service classifications for automotive gear lubricants. See>>>>>https://www.nairaland.com/3049087/all-mean#44705368

Ash - Metallic deposits formed in the combustion chamber and other engine parts during high-temperature operation.

B

Base Number (BN) - Quantity of hydrochloric (ASTM D974) or perchloric (ASTM D2896) acid expressed in milligrams of KOH equivalent that is required to neutralise all the basic constituents of a 1 gram sample of petroleum product. This property is used to indicate the capacity of an oil to counter the corrosive effects of acidic products of combustion.

BP - Abbreviation for British Pharmacopoeia usually used in reference to a purity standard for medicinal white oils, or white oils that will come into contact with foods.

Bright Stock - Refined, high viscosity lubricating oils usually made from residual stocks by suitable treatment, such as a combination of acid treatment or solvent extraction with dewaxing or clay finishing.

Brookfield Viscosity - Measure of the apparent viscosity of a non-Newtonian fluid as determined by a Brookfield viscometer at a controlled temperature and shear rate.

C

Cetane Index - A value calculated from the density and distillation mid-point temperature of a fuel, used as an alternative to cetane number to indicate relative diesel ignition quality.

Cetane Number - Measure of the ignition quality of a diesel fuel, as determined by a standard single cylinder test engine. The higher the Cetane Number, the easier a high speed diesel engine will start, and the less “white smoking” and “diesel knock” after start-up.

Cetane Number Improver - Additive which improves the Cetane Number of a diesel fuel.

Cleveland Open Cup (COC) Tester - Apparatus used to determine the flash and fire points of most petroleum products with flash points above 79°C.

Cloud Point - Temperature at which a noticeable cloud of crystals or other solid material appears when a sample is cooled under prescribed conditions.

Cold Cranking Simulator (CCS) - An intermediate shear rate viscometer that predicts the ability of an oil to permit satisfactory cranking speed in a cold engine.

Complex Grease - Lubricating grease thickened by a complex soap consisting of a normal soap and a complexing agent. Use of soap complexes gives products which have higher dropping points than similar lubricants made from normal soaps.

Corrosion Inhibitor - Additive that protects metal surfaces from chemical attack by water or other contaminants.

I had my Internship at one of the Major Lubricant Manufacturing companies in Nigeria, still an undergraduate. So, I did had a lot of first hand experience.
