Lubricating Oil

A liquid lubricant, usually comprising several ingredients, including a major portion of base oil and minor portions of various additives.

Thicker oil reduces surface contact of load-bearing surfaces. If the oil is much thicker than required, friction and losses will increase. Thicker oil increases losses through internal fluid friction and churning losses.

Reclaimer

An apparatus in which dirty lubricating oil, which often is discarded is treated and made usable, reclaimed.

Stability

Ability of lubricating oil to withstand physical change under severe operating conditions.
