How Often to Change Floor Jack Oil

Last Updated on April 19, 2023

Floor jack oil is an essential component of any floor jack. A lot of people don’t realize that their floor jack oil needs regular maintenance, just like any other element.

A floor jack is a device that uses hydraulic power to lift heavy objects. It relies on hydraulic fluid to function, and this fluid needs to be changed periodically. The reason for that is floor jack oil breaks down over time and becomes less effective. This can cause your jack to malfunction or even fail completely.

The question of how often to change floor jack oil comes naturally. Throughout this article, we’ll discuss how often you should change the oil in your floor jack and why it’s important to do so. Keep on reading.

How Often to Change Floor Jack Oil: Factors to Consider

Changing Floor Jack Oil: Factors to Consider

In general, you have to change the floor jack oil every 6 months. But, there are some contributing factors that may change the period by which we should do it.

How Often You Use Your Floor Jack:

The frequency of changing your oil will depend on your floor jack’s usage. If you use it multiple times a week, then you will need to change the oil more frequently than if you only use it once a month.

A good rule of thumb is to change the oil every 6 months or after each racing season, whichever comes first. You don’t want to wait too long to change the oil because it can start to break down and cause damage to your floor jack.

If you use your floor jack frequently or if it’s exposed to harsh conditions (e.g., extreme cold or heat), it may be necessary to change the oil more often. Conversely, if you rarely use your floor jack or if it’s always stored in a temperature-controlled environment, you may be able to go longer between changes.

The Age of Your Floor Jack:

The frequency with which you need to change the oil will depend on the age of your jack. For example, if you have a new jack, you may only need to change the oil once a year. In contrast, if you have an older jack, it might be necessary to change the oil on a more frequent basis.

In general, it is a good idea to check your jack’s oil level every six months and to change the oil whenever it begins to look dirty or depleted.

Condition of Your Jack:

If it’s starting to show signs of deterioration, then regular oil changes may be necessary. If you notice that the jack is starting to make more noise than usual or isn’t lifting as smoothly, then it’s probably time for an oil change.

Type of Oil Used:

There are different types of oils that can be used in floor jacks. Some are designed for light use, while others are meant for more heavy-duty applications. It may also cause variation in the time period a floor jack oil is safe to continue or change.


If you live in a cold climate, chances are you won’t need to replace your floor jack’s oil as often as someone who lives in a warmer climate since the cold temperatures will help keep the oil from breaking down as quickly.

Also, If you live in a humid area or if you store your jack in a damp garage, then you should change the oil more often to prevent rusting.

Is There a Way to Tell if Floor Jack Oil Has Gone Bad?

There are a few ways to tell if the oil has gone bad.

  1. Check the color. Fresh oil should be a clear, red color. If it is murky or pink, it’s time to change it.
  2. Check for leaks. Bad seals can cause hydraulic fluid to leak out, so if you see any leaks, it’s time for a change.
  3. Pay attention to how your jack is performing. If it seems sluggish or isn’t working properly like it used to, the oil may be to blame.

If you think the oil has gone bad, drain the reservoir and add fresh fluid. It’s also a good idea to change the seals at the same time.

What Will Happen if You Do Not Change Floor Jack Oil Regularly?

Most floor jacks have a reservoir of oil that needs to be changed regularly. Without oil changes, the jack will eventually stop working. The oil in the jack helps to keep the parts moving smoothly and prevents them from rusting.

Without regular maintenance, the jack will eventually seize up and become unusable. Aside from that, the oil helps to cool the jack while it is in use. If you do not change the oil, the jack could overheat and cause damage to the internal parts.

For these reasons, it is important to change the oil in your floor jack on a regular basis.

How Do You Drain Hydraulic Floor Jack Oil?

Most hydraulic floor jacks have a release valve that is used to drain the oil. To drain the oil, first, locate the release valve. It is usually located near the base of the jack. Once you have found the release valve, place a container underneath the jack to catch the oil.

Then, use a wrench to loosen the valve. Be careful when doing this, as hydraulic oil can be hot. Once the valve is loosened, gravity will cause the oil to flow out of the jack and into the container. Once all of the oil has been drained, replace the cap on the release valve and dispose of the oil properly.

How Do You Fill a Hydraulic Floor Jack With Oil?

How Do You Drain Hydraulic Floor Jack Oil

Adding oil to a hydraulic floor jack is a straightforward process, but it is important to do it correctly in order to keep the jack functioning properly. The first step is to locate the fill port, which is usually located near the top of the jack.

Once the fill port is located, remove the cap and clean any grit or grime from the port before proceeding. Next, using a funnel, if necessary, slowly add hydraulic oil to the jack until it reaches the proper level. Using the oil filler hole as a guide, fill the oil until it reaches 3/16″ above the inner cylinder.

It is important not to overfill the jack, as this can cause damage to the internal components. Lastly, replace the fill port cap and check that it is tightened securely. Also, Screw the vent screw back in place.

Is There a Substitute for Hydraulic Floor Jack Oil?

Floor jack oil can be expensive, and it can be tempting to use a substitute, such as transmission fluid or motor oil. Unfortunately, this is not recommended. Different types of fluids have different properties, and using an incompatible type of fluid can damage your jack and void the warranty.

Besides, floor jack oil deteriorates with time, so it’s important to use fresh fluid on a regular basis. If you’re looking for a way to save money on hydraulic fluid, buying in bulk is usually the best option. Otherwise, there is no alternative to hydraulic floor jack oil.

Can You Put Hydraulic Fluid in a Floor Jack?

Can You Put Hydraulic Fluid in a Floor Jack

Yes, you can add hydraulic fluid to a floor jack. Hydraulic fluid is a type of oil that is used to power many items of machinery, including jacks. The fluid is stored in a reservoir, and as it is forced through the system, it generates pressure.

This pressure is then used to lift heavy objects. As long as the fluid is clean and free of contaminants, it will not damage the jack. In contrast, if the fluid becomes dirty or contaminated, it can damage seals and cause leaks.

For this reason, it is important to regularly check the level of hydraulic fluid in your floor jack and to top up as necessary.

How Much Oil Does a Floor Jack Hold?

Floor jacks typically have a lifting capacity of 2 to 4 tons and can be operated by hand or by foot. The size and weight of the object being lifted will determine the amount of oil required for the floor jack.

For example, a 2-ton floor jack will require 2 quarts of oil, while a 4-ton floor jack will require 4 quarts of oil. The oil must be added to the reservoir in order to operate the floor jack.

When the object has been lifted, the hydraulic pressure is released, and the oil is returned to the reservoir. Depending on the size and capacity of the floor jack, it can hold between 1 and 5 gallons of oil.

Are There Any Dangers Associated With Changing Floor Jack Oil?

Are There Any Dangers Associated With Changing Floor Jack Oil

There are a few things to keep in mind to avoid any undue complications.

  1. Be sure to use the correct type of oil. Many jacks use petroleum-based hydraulic fluid, but some may require synthetic oil.
  2. Be careful not to overfill the jack. Too much oil can cause leaks and other problems.
  3. Make sure that you dispose of the old oil properly. Used hydraulic fluid can be harmful to the environment if it is not disposed of properly.

Overall, changing the oil in your floor jack is a relatively simple and straightforward task. In any case, it is important to take a few precautions to ensure that it is done safely and correctly.

So, Let’s Change Floor Jack Oil in Due Time

After reading our discussion, hopefully, you have gained a better understanding of the explanation to your question. As with anything else, there is no one-size-fits-all answer when it comes to changing the oil in your floor jack. It depends on how often you use your jack, where you store it, and what type of oil you use.

As a general rule of thumb, we recommend changing the oil every six months or after approximately 50 uses, whichever comes first. By following these guidelines, you can help ensure that your floor jack is always working properly and can stand up to whatever task you throw its way.
