Saturation Level
The amount of water that can disolve in a liquid at a given temperature.
Scoring
Distress marks on sliding metallic surfaces in the form of long, distinct scratches in the direction of motion. Scoring is an advanced stage of scuffing.
Semisynthetic
A lubricant consisting of a blend of conventional mineral oil and a synthetic hydrocarbon.
Shear Rate
The rate at which permanent shearing or viscosity loss occurs.
Solvent
A material with a strong capability to dissolve a given substance.
Stationary Engine
An internal combustion engine used to drive immobile equipment, such as pumps, generators, mills or factory machinery.
Steam Turbine
A mechanical device that extracts thermal energy from pressurized steam. The energy is converted into a rotary motion that drives a device.
Synthetic Oil
Made with products that are chemically manufactured, primarily polyalphaolefins (PAO) and esters. The chemical processes permit tight control of the molecular structure of PAOs and esters, giving the final product uniform and stable properties.
