Oil is used in various crucial different applications and has different important tasks to fulfil. Lubrication oil is used to avoid friction between moving parts and therefore to avoid wear or damages.
Hydraulic oil is used to transmit forces and the hydraulic systems are used in nearly all industries. Oils are also expected to cool or to avoid contaminations which would cause harm to the engine. Oils in modern equipment are complex and expensive liquids. It is therefore important to understand and maintain the oil. Oil can tell us long stories about the performance of the equipment.

Lube oil is the life blood of your engine! 

Oil can tell a long story about the condition of the facility in which it operates. It is important to be able to extract this important and valuable information from the oil. The oil also tells us a story about itself. Oil ages just like us humans and its lifespan is limited. But even with oil, there is no fixed, predefined lifetime. Changing the oil too soon is an unnecessary expense and bad for the environment. On the other hand, if you leave the oil in the system for too long, it can become much more expensive. Only the oil itself can tell us whether it can still be used or should already be replaced.
