When we talk to our customers about the importance of oil cleanliness in improving equipment performance and extending its life, we sometimes hear this response: “If my equipment is already damaged, what is the point of putting clean oil in it?”

The answer may surprise you. In a previous post, we looked at the impact of oil cleanliness on hydraulic system pressure efficiency. Specifically, we shared test results showing that a typical hydraulic fluid that is not certified to the equipment manufacturer’s ISO cleanliness standards can have a jarring effect on system pressure and overall system performance. Using a certified clean hydraulic fluid, however, can result in smoother pressure and efficient performance.

In the course of our testing, we took apart a high-pressure Eaton vane pump to examine the relative wear caused by typical contaminated hydraulic fluids versus a Chevron Rando HD ISOCLEAN Certified hydraulic fluid. We then put back together a pump that had experienced significant wear from a typical hydraulic fluid over a period of 150 hours, and refilled it with a Chevron Rando HD ISOCLEAN Certified hydraulic fluid.

The results were fairly dramatic. With the typical hydraulic fluid, the pressure control valve had exhibited instability, as shown by a somewhat shaky pressure control curve. With the Chevron Rando HD ISOCLEAN Certified hydraulic fluid, the exact same valve exhibits a very smooth pressure control curve.

What this tells us is that you actually can stabilize a hydraulic system’s fluid pressure and gain operating efficiency by putting a certified clean oil into a previously damaged system. Whether you’re operating an excavator on a construction site or a plastic injecting molding machine, you’re going to get much more efficient performance, higher production and improved quality by changing out a typical hydraulic fluid for a certified clean lubricant. You might even get many more hours of useful life out of the equipment that would otherwise have been cut short by sticking with a typical contaminated hydraulic fluid.

Our advice, of course, is always to “start clean.” Our testing found a clear correlation between initial hydraulic fluid cleanliness and the amount of wear on hydraulic system components. We further concluded that fluid contamination can have a negative impact on system fluid pressure and efficiency.
