ture lubricant failure. Selecting a long-life lubricant can reduce oil consumption in many cases by more than 50 percent. Still, it is important to be prudent. Don't invest in long- life lubricants for an application where they have to be changed frequently for other reasons (e.g., contamination) or where excessive leakage can't be controlled. 2. Proactive Lubricant Life Extension In normal service, lubricants age over time in a linear fashion. Eventually, they die due to additive depletion or other causes. However, life expectancy is not only related to the quality of the lubricant but also to the type and extent of in-service exposures. The most destructive exposures are contaminants such as heat, air, moisture and water. This has been discussed extensively in the pages of Machinery Lubrication. Most users dismiss the opportunity to make practical exposure changes and enhance machine reliability and lubricant life. This is a pity because contamination control often constitutes the easiest and most certain savings opportunities. Go with what works. Exposures also relate to topping up a machine that contains remnants of an aged lubricant with a new lubricant. When new lubricants are mixed with oxidized, degraded oils, they quickly degrade. You could say old, damaged lubricants are infested with diseases that can rapidly infect the new incoming lubricants. In many cases, additives in an aged lubricant should be reconstructed. Rather than disposing of all the oil and then replacing it, a far more economical approach would be to only replace the offending degraded additive.
