Hydraulic fluid transfers force through a sealed system with minimal loss, making it the working fluid behind power steering, hydraulic clutches, and other pressure-driven components on a vehicle. Low or contaminated hydraulic fluid is a common cause of stiff or noisy power steering, a soft or unresponsive clutch pedal, and accelerated wear on pumps, seals, and hydraulic lines. Browse power steering fluid, hydraulic clutch fluid, and related hydraulic fluids for cars, trucks, and SUVs to keep these systems operating smoothly.
