Hydraulic Fluid

Hydraulic fluid is a mineral-based liquid used in heavy-duty applications to move power smoothly and efficiently. The fluid travels within a sealed system to also provide lubrication and reduce wear. Changing your hydraulic fluid regularly is a step toward protecting against excess wear and tear. Without the right lubricant at work, essential systems can break down and could provide poor performance or fail. Your hydraulic fluid may be leaking if you notice dry, cracked seals or see fluid on the ground.
