1. Composition:
- Power steering fluid: Typically consists of a blend of base oils (mineral or synthetic), additives, and viscosity index improvers.
- Hydraulic fluid: Can vary in composition depending on the specific application. It may be mineral oil-based, synthetic, or water-based (glycol). Each type of hydraulic fluid has different characteristics and is formulated to meet specific requirements.
2. Viscosity:
- Power steering fluid: Designed to have a relatively low viscosity to ensure easy flow and quick response in power steering systems.
- Hydraulic fluid: Can have varying viscosities depending on the application. Some hydraulic systems require low-viscosity fluids, while others may require higher viscosities for increased load-carrying capacity.
3. Additives:
- Power steering fluid: Contains specific additives to enhance performance and protect the power steering system's components, including anti-wear, anti-foaming, and anti-oxidation additives.
- Hydraulic fluid: Can also include various additives, such as anti-wear, anti-corrosion, and extreme pressure additives, which vary based on the specific hydraulic system requirements.
4. Application:
- Power steering fluid: Exclusively used in power steering systems of vehicles to assist in steering and reduce the effort required by the driver.
- Hydraulic fluid: Used in a wide range of hydraulic systems, including hydraulic lifts, cranes, forklifts, industrial machinery, and agricultural equipment, to transmit power and provide controlled motion.
It is important to follow the manufacturer's recommendations and use the correct type of fluid in a specific system. Mixing different fluids or using an inappropriate fluid can lead to reduced performance, component damage, or even system failure.
