The use of synthetic lubricants in various industrial and automotive applications is becoming more and more common, due in part to heavy marketing of synthetics. The word “synthetic” has nearly become synonymous with high quality or high performance. However, it should not be a given that a synthetic formulation is always the right choice. Those responsible for choosing lubricants have to decide between synthetic and mineral oil based lubricants, and – if a synthetic is the right choice – they have to decide what type of synthetic lubricant to use. This decision can impact the health and longevity of the machinery, as well as an organization’s operational costs and eventually the bottom line. Base fluid type should not be the only consideration. Additional factors that should be considered in the lubricant decision-making process include environment, equipment type, application technique, speed, load, temperature and OEM recommendations.
