What Type of Hydraulic Fluid for the Floor Jack Do I Need?

Hydraulics consist of systems where power and energy are transferred via fluids. Hydraulic fluids, also known as hydraulic oils are used in several types of equipment, machinery, and across different industries.

Did you know: Hydraulic systems are applied in construction, agriculture, ship building, mining, chemicals, aviation, environmental technology, etc.?

The following write-up specifies everything you must know before you purchase hydraulic fluid.

What Kind of Fluid Does a Hydraulic Jack Take?

In order to maintain stability with hydraulics and weight shifting significantly in your hydraulic jack, you must use an oil-based or water-based fluid. Fireproofing, as well as the ability to filter itself for a prolonged period of time, should be among its qualities.

Most hydraulic jack oils have anti-wear properties, making them suitable for lifting heavy objects repeatedly. Due to this a Hydraulic Jack need oils that can handle heavy work.

What should be the features of suitable hydraulic fluid for the floor jack?

There is an abundance of information about hydraulic jack oil on the internet. This includes what it is, the types available, and how to determine which type of hydraulic jack you need to ensure safety and performance.

Due to the fact that hydraulic oil is intended to maneuver large machinery with significant weight limitations, hydraulic oil is not compressible.

To know which floor jack oil type you must get, please be aware of the below-mentioned features.

  • Viscosity

Viscosity determines the hydraulic fluid’s flow resistance. Owing to having a profound impact on the operation of a hydraulic system, it is rightly considered the most significant characteristic.

When hydraulic fluid is excessively thin or has low viscosity, it does not seal the components right. This wears down the parts and causes leakage. When the hydraulic fluid is thick or has high viscosity, it will be too challenging to pump. Such a fluid also decreases the operating efficiency.

Most hydraulic fluids are capable of retaining optimum viscosity during operations in hot or cold temperatures. They could effectively and consistently transmit power.

  • Thermal Stability

Thermal stability allows the hydraulic fluid to stop breakdowns at high temperatures. Anti-wear additives degrade down the road, and this process becomes fast when the temperature increases.

When thermal stability is poor, you have to face varnish and sludge. These clogs filters, escalates downtime, and minimizes flow. As the anti-wear agents decompose too at high temperatures, the acids form and they attack the yellow and bronze metals in hydraulic system parts like piston pumps.

Some hydraulic oils are made of high thermal stability. They decrease different problems and the hydraulic system works for a prolonged period.

A few more features to pay attention to are compressibility, oxidation stability, wear resistance, foam resistance, corrosion and rust protection, seal compatibility, and demulsibility.

What type of hydraulic fluid for the floor jack do I need?

To choose the right hydraulic fluid for the floor jack, please consider the three properties stated below.

  • Lubrication

Hydraulic fluids are known for being an excellent lubricant. This property is also the means by which the power is transferred all across a hydraulic system. So, the fluids are a lube and a power transfer solution. This dual role is what makes them unique.

  • Qualities

If you want the best hydraulic fluid, you must make sure to take into account the following qualities – non-compressible, thermally stable, resistance to water corruption, fire resistance, and anti-wearing.

  • Low Forming Quality

Hydraulic fluid quality and levels can impact the system’s performance to a great extent. Low levels can cause air pollution. Fluid contamination can lead to many temperature issues. Leaks can worsen both these issues.

Which is the Best Oil to Use in a Hydraulic Jack?

Hydraulic oil specifically designed for this equipment and viscosity requirements is the best oil to use in your hydraulic jack. Hydraulic oil comes in three different grades:

  1. 32
  2. 46
  3. 68

The type of oil you should purchase will depend on the size and weight of your hydraulic jack, as well as the type of work it performs regularly. These grades are also available in two different types of oil:

  1. R&O
  2. AW

R&O hydraulic oil refers to rust and oxidation, whereas AW refers to anti-wear. In both cases, the equipment is protected and prevented from being damaged. AW is typically regarded as a higher-end hydraulic oil. For equipment without premium requirements, R&O will suffice.

What can you use as a substitute for hydraulic oil?

Are you looking for a hydraulic jack fluid substitute? If yes, you can look into the below options.

  • Vegetable Oil

Oils extracted from soy, canola, and sunflower are used for making food. These can also be used in the place of hydraulic fluid. But it can be a sort of a gamble as the hydraulic system’s performance is influenced by the base oil you have chosen and the additives you have added.

Vegetable oils are more beneficial than other mineral oils. They are not toxic, have high flashpoint, have excellent lubrication capacities, and are good for the environment.

Vegetable oils are however extremely expensive. They cannot perform in lowest temperatures, and are subjected to decreased oxidation resistance.

  • Engine Oil

Engine oil can work amazingly as hydraulic fluids. However, you cannot use a multigrade engine oil in a system that is designed for high viscosity.

  • Transmission Fluid

Can I use transmission fluid in a hydraulic jack? Yes, you can. Automated transmission fluid has substantial amounts of viscosity. However, ATF has many additives, and these additives can break down the hydraulic seals. You must use ATF only if the system has smaller jacks that you can operate by hand.

  • Power Steering Fluid

Power steering fluid can be used in hydraulic systems. However, unlike ATF, they are not able to remove grease and dirt.

  • Gear Oil

Can you use gear oil in a hydraulic jack?  Yes. Gear oil can act as a lubricant. It makes sure the pinion wheels work properly even under high tension.

What fluid or oil cannot be used on the floor jack?

  • Motor Oil

You should never use motor oil on the floor jack. Motor oil runs at an extremely high temperature. The oil will start burning inside the hydraulic system

  • Compressor Oil

Compressor oil bears almost no resemblance to the hydraulic fluids stated above. It can destroy the seals and can blow up the whole hydraulic system.

  • Brake Fluid

No, you cannot use brake fluid as hydraulic fluid on the floor jack. It will damage the seals to a great extent.

How to add hydraulic fluid to a floor jack?

Mentioned below are four steps you must implement when adding hydraulic fluid to the floor jack.

  • Place on a Leveled Place

Always place the jack on a level platform. This will stop the jack from rolling when you are working. This also keeps the oil level stagnant.

  • Release the Valve

Release the valve. Doing so would lower the jack and you can reach the filler plug. In case of a few jacks, rotating the handle counterclockwise also works.

  • Check the Oil Level

Check the oil level. You must make sure it is not too high or too low.

  • Fill with Hydraulic Oil

Fill the reservoir with hydraulic oil. The oil must be beneath the lower rim of the filling hole. Wipe away excess oils. You should use funnels to keep spills at bay.

How often do you change floor jack oil?

You do not have to change the oil in the hydraulic floor jack frequently. When you purchase a jack, the oil in it lasts for almost two years. Check the oil level every now and then to make sure it is functioning seamlessly.

Is there a difference between hydraulic fluid and oil?

Is hydraulic fluid and hydraulic oil the same? Well, hydraulic oil is a fluid. But hydraulic fluids sometimes have plain water, salt solutions, and water and oil emulsions instead of only oil.
