Today’s hydraulics are rapidly evolving. They are becoming more compact, lighter, working in environmentally friendly arenas, and require greater fuel economy. Higher performance pumps and motors cause higher pressures and temperatures, and hydraulic fluids must be able to work under these new and more severe conditions.

Mobile hydraulic systems are now designed to extract more power from these smaller systems. Smaller hydraulic pumps and motors are not only running at much higher pressures, fluid reservoirs are also smaller so that less fluid is more rapidly circulating. This fluid cannot remain in a reservoir to cool, or to let water and contaminants separate and settle, or entrained air to dissipate. The systems, as a result, are running hotter, losing viscosity and oxidation which, in turn, degrades the fluid and produces sludge.

Consequently, there is a growing demand for fluids that have a long life, that can stand up to longer drain intervals, that are sludge free, that have improved water separation, and that have greater durability over time. And, it is beneficial for these fluids to be compatible with those that are already used in the industry.
