Long-range operating economy is achieved by using as large amount of each raw material as necessary to provide maximum lubricating benefits.

Short-range economy is achieved by cutting down on the volume or percentage of the more expensive raw materials. A commercial grade lubricant may contain some of the same raw materials as a custom-built lubricant, only in small volume or percentage. s
