Power Steering Fluid Color – All You Need To Know

Vehicles can use either manual or power steering. However, modern vehicles mostly have power steering. Power steering is of two types which are hydraulic power steering and electric power steering. Hydraulic power steering uses Auto Transmission Fluid, which can also be used in transmission gear. There is, however, a fluid made for the steering system known as the power steering fluid. An example of a power steering fluid is Lucas Oil.  The fluid is slightly different from the automatic transmission fluid. So, what is the power steering color?

It protects the moving parts of the system and keeps the steering mechanism smooth. Failing to use or use contaminated steering fluid will harm the steering pump or the whole mechanism. That is why you need to know what color power steering fluid should be.  Power steering fluids are found in different grades and brands like Genuine Honda Fluid. They are type IV, III, III, and I. This article will help you to know the difference as well as their color.

Power Steering Fluid Types

There are certain things to consider before you choose a steering fluid for your vehicle. The type of steering fluid mainly depends on the model or make of a vehicle. Some vehicles tend to use ADF for the steering system. Most of the newer models use synthetic power steering fluids. The fluids are much better since it flows better under low temperatures, among other benefits.

Lots of other vehicles use universal power steering fluids. In some instances, manufacturers recommend specific power steering fluids containing particular additives. It is, therefore, important to consult the owner’s manual for the best power steering fluid for your vehicle. Let us discuss these types and what power steering fluids are made of.

1. Mineral Power Steering Fluids

Mineral fluids are made with refined petroleum fractions and additives, which improve the performance properties of the oil. The main benefit of using this fluid on your steering system is that it has no aggressive impact on elements of rubber. The fluid is also not expensive compared to the other types of power steering fluids. The fluid will, however, serve for a short period. It is also likely to form foam regularly.

2. Semi-Synthetic Power Steering Fluid

This fluid comprises both synthetic and mineral substances. They have a low degree of viscosity, good lubricity, and are resistant to foam formation. On the downside, the semi-synthetic steering fluids have a destructive impact on rubber elements in the steering system.

3. Synthetic Power Steering Fluid

The synthetic fluid is an ideal steering fluid to use if the car manufacturers recommend it. They are made with a small number of refined petroleum fractions, polyesters, and polyhydric alcohols. They also have special additives that reduce their destructive impact on power steering rubber parts. At low temperatures, synthetic power steering fluids flow smoothly.

The operations of the steering system are smooth, thus increasing its durable life. Most European car manufacturers recommend unique steering fluids for their vehicles. Most of the fluids recommended here are high-performance and meet DN51 524T3 and ISO 7308 standards. Synthetic power steering fluids have low viscosity, resistance to foam formation, low viscosity, can work under extreme temperatures, and have a long service life.

4. Universal Fluids

Universal power steering fluids are compatible with many of the power steering systems. You may wonder what power steering fluid universal and why it is preferred is. These types of fluids have special additives that offer different benefits. Universal power steering fluids reduce stiffness and friction by improving the performance and responsiveness of the steering parts.

These power steering fluids also feature properties for preventing corrosion, sealing small leaks, and reducing wear and tear on the steering components. However, you are advised to check the viscosity and chemical compatibility with the type been used in the steering system. The properties in the new fluid should match with the one earlier used in the system.

Frequently Asked Questions(FAQs)

Q. What is Power Steering Fluid Made Of?

Most people wonder, what is power steering fluid made of? Power steering fluid is a type of hydraulic fluid made with either mineral oil or silicone. The make of the fluids may differ from one manufacturer to the other. Some power steering fluids are made with synthetic-based oil.
