Glossary of Terms


AGMA American Gear Manufacturers Association 
API Gravity A gravity scale established by the American Petroleum Institute and in general use in the petroleum industry.
API Service American Petroleum Institute Service- Designation for Performance Levels of various petroleum products.
ASTM - International Formerly known as American Society for Testing and Materials. Develops standards, guidelines and test methods used in diverse industries ranging from metals to construction, petroleum and consumer products. 
BHT Butylated Hydroxy Toluene – Inhibitor-  Inhibits the oxidation of other chemicals. Commonly added to Transformer Oil to help prevent the formation of harmful chemicals and corrosion. Also known as DBPC Antioxidant.
CNG Compressed Natural Gas. Alternative fuel sourced from oil and gas drilling and as a byproduct of landfills and wastewater treatment plants. 
DBPC - Antioxidant Ditertiary-butyl-paracresol -- Inhibits the oxidation of other chemicals. Added to Transformer Oil to help prevent the formation of harmful chemicals and corrosion. Also known as BHT Inhibitor.
DEF  Diesel Exhaust Fluid - DEF is a colorless and non-toxic solution of 67.5 percent water and 32.5 percent automotive-grade urea. The U.S. Environmental Protection Agency (EPA) classifies DEF as “non-hazardous.”
EP  Extreme Pressure; Most often designated for Grease in automotive and industrial applications that are subjected to higher than standard operating conditions.
Esters Name for a group of chemical compounds the most common of which includes Acetates.
GEO  Gas Engine Oils 
IBC Intermediate Bulk Container - A container generally used for transport and storage of fluids and bulk materials, typically 275 or 320 gallons.
ILSAC  International Lubricant Specification Advisory Committee. 
ISO International Organization for Standardization
ISO VG  International Organization for Standardization  Viscosity Grade - a measure of the fluid’s resistance to flow.
GTL Gas to Liquid- Process to convert gas extracted from wells to liquid primarily to expedite transport and distribution.
HTHS High Temperature - High Shear
Ketones A group of organic compounds or chemicals that includes many industrial solvents such as Acetone.
LNG Liquified (Liquid) Natural Gas.
Low-SAPS Oils Low-SAPS Oils additive technology. Low Sulfated Ash, Phosphorus, Sulfur. These oils are specifically blended for diesels with particle filters and gasoline engines with 3-way catalytic converters.
Naphthenic Base Oils A characterization of certain petroleum products prepared from naphthenic type crudes (crudes containing a high percentage of ring type hydrocarbon molecules).
NFPA National Fire Protection Association
NLGI  National Lubricating Grease Institute
NOx  (often written NOx) refers to NO (Nitric Oxide; Nitrogen Monoxide) and NO2 (Nitrogen  Dioxide). Gas produced during combustion, especially at high temperature.
OGM  Open Gear Machinery
PAG Polyalkylene glycol
PAN  Phenyl- Alpha-Napthylamine – a commonly used antioxidant 
PAO  Poly-Alpha-Olefins -  are useful as synthetic lubricants such as synthetic motor oils for vehicles; can be used over a wide temperature range.
Paraffinic Base Oils A characterization of certain petroleum products prepared from paraffinic type crudes (crudes containing a high percentage of straight chain aliphatic hydrocarbon molecules). Lubricating oils made from these crudes are normally distinguished from similar oils from other crudes by higher API gravity and higher viscosity index.
PEL  Permissible Exposure Limit
PGE Polyglycol-ester
PIB Polyisobutylene or polyisobutene --added in small amounts to the lubricating oils used in machining to provide a significant reduction in the generation of oil mist, thus reducing the operator's inhalation of oil mist.
R&O Oils Rust & Oxidation Inhibition Oils. 
SAE Society of Automobile Engineers; Sets standards for design, manufacturing and performance for Automobiles and Trucks 
SARA 313 Superfund Amendments and Reauthorization Act (SARA) of 1986 
SCA  Supplemental Coolant Additive. A compound added to Antifreeze/Coolant to extend its useful life and improve performance.
SCR  Selective Catalytic Reduction - used in diesel truck engines, is a means of converting nitrogen oxides, also referred to as NOx, with the aid of a catalyst into diatomic nitrogen, N2, and water, H2O. The selective catalytic reduction (SCR) is an after-treatment system composed of a supply module, a diesel exhaust fluid (DEF) tank, a dosing module and an SCR catalyst.
THF  Tetrahydrofuran – An organic compound used as a base to make certain polymers; THF is also used as an industrial solvent 
TPE  Thermoplastic  Elastomer
Transformer Oil  Also called Insulating Oil. A highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant.
UTH Universal Tractor Hydraulic Oil; Universal Tractor Fluid; Universal Farm Oil. A multi-function oil used in tractors and other off-road vehicles. 
VM&P Naptha  Varnish Makers & Painters Napthalene
