EAL Longevity and Why it Matters

February 28, 2022

RSC Bio Environmentally Acceptable HEPR type Lubricants maintain lubricating stability well beyond a five-year dry docking cycle. Our ENVIROLOGIC and FUTERRA EALs regularly meet and or exceed performance requirements of the most demanding applications including stern tube and gear oils. Not all four types of EALs can demonstrate the lubricating stability that our best-in-class lubricants can.  Here’s one of many oil analyses measuring the kinematic viscosity of RSC Bio’s HEPR lubricant in every day use in a stern tube application.

A typical deep water vessel dry dock cycle is five years.  In this example, it’s been nine plus years since the stern tubes of the M/V Edwin H. Gott were filled with EnviroLogic HEPR type EAL and the oil is still in spec.  This is because RSC Bio’s environmentally acceptable lubricants are engineered for hydrolytic and oxidative stability.  EALs are the only type of lubricants we offer.  Let us help you decipher the differences among EALs and conventional lubricants alike, test criteria and why it all matters.
