Can I Use a Power Steering Fluid in the Hydraulic Jack?

Using a power steering fluid in the hydraulic jack is not suggested. The power steering fluid doesn’t exert enough effort to lift a jack capable of raising a two-ton vehicle; it is ineffective. Make no attempt.

Keep in mind that the power steering fluid is critical since it enables the passage of power. Theoretically, it is hydraulic fluid, and so the liquid is used. In any event, hydraulics cannot be swapped even though numerous variations exist with different properties.

The most suitable fluids to utilize as a substitute for a hydraulic jack are P/S fluid, ATF, and motor oil. This article will explain why this connection is impossible, why it is not advised, and alternative workarounds. Find the best responses to the commonly asked questions and a summary of the article. Read along carefully!

Things you should know before use;

  • Please familiarize yourself with how the power steering operates with its fluid and hydraulic jack.
  • Understand how to replace power steering fluid and hydraulic components.
  • Use the hydraulic jack to select the ideal power steering fluid.
  • Ensure you understand the significance of changing a power system and hydraulic jack.
  • Hydraulic and steering system malfunctions.

1. Usage

It is always prudent to check the manufacturer’s specifications before utilizing a hydraulic fluid. For direct tasks, guidelines created can be altered. A power steering fluid connection is the optimal way to accomplish your objective in the rubber system.

Caution should be exercised when working with this type of fluid. That is why it is always recommended to consult the specifications before initiating any activity.

2. Specificity

To avoid distorting the rubber connection, ensure you don’t add additional hydraulic fluid to the steering system. Most light vehicle manufacturers will explicitly recommend utilizing power steering fluid strictly for specified vehicle models.

The hydraulic fluid used is determined by the vehicle’s model and type. The liquid precludes it from being utilized on all vehicles, as some manufacturers believe it is not the safest form of operation.

You can utilize power steering or the brake fluid without applying considerable tension. It functions flawlessly but stiffens up inside the seals. The most cost-effective way to keep your machine going is to obtain a full cover of hydraulic jack oil, a 10/20W low-weight motor, or machine oil.

Automatic fluid transmission is possible in particular circumstances, and it works best when no other means to use the fluids are available. From the training pitch, when you press the brake pedal, the brake fluid converts the imparted force to pressure in the lower section, and the rear brakes bring the vehicle to a complete stop due to the incompressibility of liquids.

The critical factor that precludes the compressor from being utilized is that it lacks certain components found in hydraulic oil. Anti-wear additives are included in this section. When the hydraulic system operates at less than 600 pounds per square inch, which is the low pressure, the compressor becomes an inadequate match for the task at hand.

Bear in mind that while brake fluid is an excellent substitute for hydraulic fluid, it is not recommended for use in a bottle jack. Alcohol is contained in brake fluids, which adversely affects the machine’s seals. Always inquire about a company’s guarantee and specifications.

Can you use ATF fluid in a hydraulic jack?

Due to the negative consequences of utilizing incompatible fluids, using any material that does not conform to the manufacturer’s standards is not suggested. While both automatic transmission and power steering fluids are sourced from the same hydraulic fluid system, they cannot perform the same functions due to the additives present. The jack’s seals may be compromised.

The best hydraulic fluid substitute is an SAE 30, 20, or 10 oil with low-performance ratings. It is primarily employed in quarrying and construction settings that include the usage of large machines. It is replaced in the same manner with hydraulic oil ISO 32, ISO 46 COR, and ISO 68.

It is important to know that hydraulic and transmission fluids are not compatible. All being hydraulic fluid-based, the transmission fluid transports power from the engine to the transmission.

By contrast, hydraulic oil lubricants come in a variety of types, including the following:

  • CVT fluid 
  • Power steering fluid
  • Brake fluid 

While transmission fluid may be preferable in a log splitter, it is not recommended in a hydraulic jack. It is beneficial to have a basic understanding of how various fluids behave in diverse systems. Therefore, AW22 or 32 hydraulic oil is the optimal choice for a wood splitter, as it provides superior performance.

Occasionally, when temperatures fall below 32 °F, automatic transmission fluid is used in place of hydraulic oil to achieve the highest potential performance. Additionally, automatic transmission fluid is ideal for floor jack systems. If you’re having trouble adhering to the manufacturer’s specifications, the best action is to utilize automatic transmission fluid.

Sometimes, the user may replace the hydraulic fluid with gear oil. This is possible; however, the difference is due to the viscosity of the two liquids. Through the pistons, the hydraulic oil transports energy to the system.

Thus, when comparing the two, gear oil has a higher viscosity to facilitate lubrication, form a thin coating, and flash away from the existing particles. Additionally, heat is evacuated from the system.

Is hydraulic steering fluid the same as power steering fluid?

This brings about the difference between hydraulic steering and power steering systems.

Here is a quick table;

FeatureHydraulic steering systemsPower steering systems
Fuel consumptionLess fuel economySuperior fuel economy as they utilize an electric motor to execute commands. 
MaintenanceRequire extra attentionFunction with a set of instructions.

1. Fuel consumption

Compared to hydraulic steering systems, power steering systems offer superior fuel economy. The logic is self-evident: power steering systems utilize an electric motor to execute the user’s steering commands. Vehicles equipped with EPS systems lack hydraulic pumps and pistons, therefore eliminating the function of hydraulic systems.

2. Repair services

If you notice that the controls are not responding appropriately to the commands, this is a sign of a problem with the power system. Leaks can occur in hydraulic systems, which can be repaired by filling the car with power steering fluid.

Technically, this fluid is a hydraulic fluid; nonetheless, it is the only one compatible with a power steering system. Other forms of hydraulic fluid are utilized in autos, and it is critical that they avoid contact at all costs.

3. Maintenance

Hydraulic systems require extra attention since they function using a fluid, as opposed to electric systems, which function with a set of instructions.

4. Improved handling

Both provide the same level of comfort; it basically depends on the user. To determine this, experiment on your own and determine which one makes you feel most at ease.

While using a hydraulic steering fluid in case of an emergency feels right, excessive amounts of the oils might cause the power steering system to become distorted. When coping with search fatalities, it is necessary to be aware of the precautions. Among the several varieties of hydraulic steering fluid are the following:

  • Transmission oil.
  • Hydraulic fluid.

Although power steering fluid is not utilized as the hydraulic oil in tractors, it works effectively as a power steering fluid. A power steering system comes in various configurations, each with its own set of functions.

A hydraulic system operates flawlessly by pressurizing a large amount of fluid, but an electro-hydraulic system utilizes an electric engine to force pressure gradient. Consequently, the electric system operates with the assistance of electric engines and sensor systems.

Frequently Asked Questions:

  • Which system performs better, power steering or hydraulic?

Answer: Since it is powered by an electric motor, power steering is the most fuel-efficient. Hydraulic systems require more maintenance compared to power steering systems. Hydraulics repairs are comparatively straightforward in comparison to power steering issues.


In conclusion, the user should understand why utilizing power steering fluid in a hydraulic system is not appropriate, as widely explained above. The article has also provided the optimal matches in the steering systems.

When interacting with either of the two, it is critical to understand how they operate. If you are experiencing difficulties in fixing, kindly seek assistance from a mechanic.
