What Is A Power Steering Fluid?
There are many processes on your car that use hydraulics to make that process work better and smoother. Such is the case with brakes and power steering. Power steering makes your car easier to turn even when you are going very slowly. Power steering fluid is the specially made fluid that is pumped through the hydraulic lines to make your power steering work. Without this special fluid in the lines, your car steering wheel would take a considerable amount of effort to make it turn.
What Is Power Steering Fluid Made Of?
We explain this a little further on in the types of power steering fluid there are. But it basically comes down to three basic types that have similar characteristics but different chemical makeups. The most popular of which are synthetic blends which feature a high amount of silicone and other proprietary additives in them. Natural mineral oil also works very well but is not as popular as synthetic blend power steering fluid. All power steering fluid systems many years ago used to use transmission fluid; it too is a synthetic blend fluid but it does not have a high amount of silicone in it.
What Color Should Power Steering Fluid Be?
When transmission fluid was used exclusively in vehicles as power steering fluid it always had a red tint to it. Synthetic blend power steering is mostly amber in color but some blends run to the clear side too. Mineral oil is yellowish or light amber in color but it’s also not uncommon for some manufacturers to put dye in it.
Power Steering Fluid or Automatic Transmission Fluid?
The choice nowadays is dedicated power steering fluid. That’s because it does a better job of protecting O-rings, hoses, and seals in your car’s power steering system. Vehicle’s that used transmission fluid in their power steering systems originally are usually switched over to regular power steering fluid if their systems are ever flushed.
How Does The Power Steering Fluid Work?
Power steering fluid is just a form of hydraulic fluid that is specially made for your power steering system on your car. Like all hydraulic fluids, it needs to be pumped to make it work. The power steering pump is connected to a belt coming off a pulley on the engine. As this belt moves, it then spins the power steering pump and causes it to continuously pump the power steering fluid through the system.
Power Steering Fluid Buying Guide
Here are some things that you need to consider when buying power steering fluid.
It’s hard to believe in this day and age that power steering fluid has not been made so it a has universal fit like motor oil. Unfortunately, that’s not the case. You have to be very careful that the steering fluid you buy matches what your vehicle specs require. If not it can lead to performance issues or premature seal and parts breakdown. It should say on your vehicles power steering reservoir cap what type of fluid your particular vehicle uses. If not, check your owner’s manual or call your car’s manufacturer.
There are three main types of power steering fluid that are found in the auto marketplace. They are:
Mineral Oil Based
This one can be a little confusing and it’s also getting harder to find mineral oil-based power steering fluids. But some auto manufacturers say they are very suitable to use. Mineral oil-based power steering fluids were the first fluid alternatives to transmission fluid in American made cars. If your car uses mineral oil-based power steering fluid, it will usually have a green-colored cap on the reservoir tank.
They call most power steering fluids that are made today synthetic blends. Of course, that does describe how they are made but it does not differentiate them much from older transmission fluids that were once used as power steering fluid. These modern synthetic blend power steering fluids have a high amount of super-lubricating silicone in them.
OEM transmission fluid
This is what used to be used in all cars as power steering fluid many years ago. It is a synthetic blend transmission that lacked the high silicone content that today’s synthetic blend dedicated power steering fluids have. It’s ok to use in older cars that already use it as power steering fluid. Be sure to never mix it with newer types of transmission fluid.
Be aware that these are not all made using the same type of formula. Many times which one you buy will come down to warranty conditions and personal preference. We will go into more in-depth detail about the different types of power steering fluid after the buying guide.
Viscosity/Working temperature range
All power steering fluids will usually list their working temperature change range. This is especially important to consider if you live in places that get extremely cold or experience extremely hot temperatures. That’s because under certain high heat conditions or extremely low temperatures certain types of power steering fluids do not perform properly.
Viscosity plays a role in this too. A power steering fluid that has a high viscosity tends not to break down under higher heat conditions. So once again consider the viscosity of the power steering fluid you are thinking about buying if you live in an area with warmer temperatures.
Just like you may have seen in our garage floor paint reviews, most power steering fluids have the same base ingredients in them. Many times a power steering fluid maker will have their own proprietary blend of additives that they put in their particular steering flood. These additives can take a decent power steering fluid and turn it into a very good one. Some of these additives are well-made and do a better job of protecting the inside of your power steering system than other brands will. So be sure to note what special additives any power steering fluid you are thinking about buying has.
If you are not careful, buying some types of power steering fluid can be expensive. Especially if buying it in smaller containers. So check the cost per ounce of the particular power steering fluid you are thinking about buying. There may be a similar style of fluid that is much cheaper.
Not all power steering fluid products come with a warranty but some do. These are manufacturers that have a ton of confidence in their products ability to do its job. This is something worth considering when shopping for the best power steering fluid.
What Are The Different Types Of Power Steering Fluids?
Not all chemical formula’s for similar type fluids are the same. So too is the case with power steering fluids. You will find different types of blends used to manufacture them. The most common ones are:
Most Common Types Of Power Steering Fluids
Mineral Oil Based
This type of power steering fluid was developed to be an all-natural alternative to manufacturer-recommended power steering. They also do not have a lot of other additives in them as synthetic type power steering has. Mineral oil-based power steering does not need them because of how well mineral oil acts as a natural lubricant and performs well even under higher heat conditions.
Synthetic Oil Based
This is by far the most popular type of power steering fluid. It’s used on just about every single production car that is produced these days. It can even be used in older cars if the entire power steering system is flushed and replaced with synthetic fluid. It contains a high amount of silicone and other protectants and lubricants.
OEM power steering fluid
While newer cars and vehicles or those that have had their transmission fluid replaced use the two types of power steering fluid mentioned above, older autos often have dual-purpose transmission fluid inside of them. This used to be standard procedure in the auto industry to use transmission fluid as power steering fluid too.
The big automakers often used their own formulas for their brand transmission fluid. They would require their particular brand to be used in order to stay in compliance with warranty conditions. These OEM brand transmission fluids had names like Mercon, Dexron, Type F, and ATF +4. They are still ok to use, but synthetic based and mineral-based power steering fluids are thought to work much better.
Benefits of Using Power Steering Fluid
Power steering fluid is considered a vital fluid in your car for a reason. Here are some of the benefits of using it.
- It lubricates and protects your entire power steering system. This helps seals, O-rings, and other power steering system parts last longer.
- Power steering fluid helps stop the squeaking noises that were once commonplace in most power steering systems.
- It makes your car much easier and faster to steer. It takes a lot of effort to do this if your power steering fluid is lost or is very low.
- Power steering fluid is designed to promote even pressure and even flow through your entire power steering system.
How to Check Power Steering Fluid
Like any other important fluid in your car, the level that is in your car has to be checked periodically. This is to ensure that you do not experience a power steering loss while you are driving because your fluid level is too low.
Here is how you check your power steering fluid:
- Step 1: Pop open your hood.
- Step 2: Locate your power steering reservoir.
- Step 3: You will see a line near the top of the power steering reservoir that says ‘fill to here’ or ‘proper level’ or something else along those lines. See where the actual fluid level is compared to where the indicator line is.
- Step 4: Add power steering fluid into the reservoir if the actual fluid level is under the proper fill line.
How Often To Change Power Steering Fluid
To be honest, power steering fluid is not an auto fluid that needs to be changed regularly. That’s because it flows through a relatively clean power steering system that does not build up dirt or grime. But there are times it does indeed need to be changed.
As with any system in an automobile that has a liquid flowing through it, there does tend to be some parts breakdown over time. There can be trace amounts of rubber from seals, hoses and even some small metal fragments. While many manufacturers do not give a timeline for changing power steering fluid, we think that changing it every 5 years or 50,000 miles or so could be beneficial.
Also, power steering fluid is normally amber-colored in nature. If you check your power steering fluid and it’s extremely dark, that means it needs to be changed as soon as possible.
Power Steering Fluid FAQ’s
Here are some of the frequently asked questions we get regarding power steering fluid.
- Question: How can I tell if I need to add more power steering fluid to my car?
Answer: There are several telltale signs that your vehicle may be low on power steering fluid. Of course, the most obvious is your steering wheel starts to take more effort to turn. Your vehicle may also make a loud squealing noise as you turn your steering wheel. You should also check the fluid level in the power steering reservoir every time your owner’s manual says you should check your oil.
- Question: I know they used to use transmission fluid in the power steering system in all makes and models of cars years ago. Is it still ok to put in my newer car too?
Answer: The answer here is no. There is a reason that newer cars do not use transmission fluid anymore in their power steering systems. That reason is there are better alternatives now. Transmission fluid is synthetic based and it’s widely thought now that mineral-based and silicone-based transmission fluids provide more protection for your power steering system.
- Question: How do I know what type of power steering fluid to put into my car?
Answer: The answer here is to check the cap that covers your power steering reservoir. If it is the original cap, then it should tell you exactly what type or types of power steering fluid should be used in your vehicle. It should also be clearly stated in your car’s owner’s manual.
- Which are the right lubricants for your car?
People do not talk about power steering fluid like they talk about changing the oil on a car but don’t mistake that for meaning it’s not a vital fluid. Your car would be very hard to turn at slower speeds without it. So it’s definitely a vital fluid that is worth spending a little extra money to get the best power steering fluid possible.
