When people first started driving cars, they had to use a lot of manual force to get the steering wheel to turn. Now, thanks to technology, we no longer depend on brute strength to make a turn. However, things will deteriorate and wear down over time. Leaks happen with age, which is why we’ve compiled a list of the best power steering stop leak fluids to help prevent your power steering system from tightening up.

Benefits of Power Steering Stop Leak

  • Prevent steering wheel lockup. Modern cars tend to all have power steering, which means you have more control over the steering wheel. In the early days of the car, steering was much more difficult with mechanical linkages that left you cranking the wheel hard when you needed to turn. The fluid powering your steering wheel keeps it loose; without it, the wheel will start to lock up and be much more difficult to control.
  • Keep yourself safe. Making sure your car is topped off with power steering stop leak and fluid means you’ll be safer on the road. There’s no risk of the steering wheel locking up on you mid-drive, preventing you from turning or stopping the car.
  • Improve performance. Checking to make sure the power steering is constantly getting fluid will help keep the car running properly. Over time, a leak will wear down your car’s power steering and could damage other parts of the car. Making sure the reservoir where the fluid is kept isn’t leaking will keep your car running smoothly.
  • Save some money. Stopping a power steering fluid leak will ultimately save you money. Catching it before it gets worse means you won’t have to take the car to the shop for a full power steering repair, and doing nothing about it may lead to other problems and leave you with a hefty cost to your power steering unit.

Types of Power Steering Stop Leak

Synthetic Oil

Synthetic oils contain a lower viscosity, which makes movement smoother for car parts and reduces internal friction. They are made up of additives that help corrode rust and are typically thicker to fill leaks and get rid of dirt and grime.

Power Steering Stop Leak Pricing

  • $5-$35: With power steering stop leak fluid, you mainly pay for the size and capacity of the container. Within this price range, anything around 12 ounces and below falls here.
  • $35 and up: This price range has larger bottles and containers that offer more solution for more applications. With power steering stop leak solution, it may be best to buy it in bulk to make sure you’ve got extra just in case you run out when you need it most.

Key Features


Before choosing the best power steering stop leak, you need to read the label carefully. Not all anti-leak fluids will work for every car. Many are specifically designed for certain models like Honda or Ford. Make sure to double check the fluid before buying to make sure you don’t pour the wrong power steering stop leak into your car.


Additives in power steering stop leak fluids work to remove debris, neutralize acidity, and fill leaks. However, they are not a permanent solution to fixing a leak in your power steering. Over time, a leak can start again, and you’ll have to add the fluid again.

Other Considerations

  • Frequency of Use: Before buying a particular power steering stop leak, it is important to consider how frequently you need to use it and what effect it will have on your vehicle in the long-run. Keep in mind that the power steering stop leak can be used multiple times before running out.
  • Bottle Size: If the leak is large and you’re unable to reach a mechanic, opting for a larger bottle size or more bottles is a good solution. Leaks aren’t filled or stopped instantly; they take time and several applications to be fully stopped up. This means you will use a lot of the fluid and may need more of the compound to get results.

Best Power Steering Stop Leak Overall: BlueDevil Power Steering Stop Leak 00232

BlueDevil makes it easy to put an end to leaking power steering fluid. The solution is made up of the company’s ‘Pour ‘n Go’ formula for simple and quick application to get you back on the road faster without the steering wheel tightening up. The liquid fills the spots where leaks are frequent and improve the condition of the power steering fluid and reservoir.

The formula also seals rack and pinion systems as well as differentials. A great feature about this power steering stop leak is it can be used on both diesel and gasoline engines. The liquid also works to recondition hardened or worn rubber seals, loosening them and making them more pliable. 

While it may be quick and simple to pour into the power steering fluid reservoir, it may take a few days until you see results. It’s not a “pour and wait a few minutes” kind of solution. You’ll need to drive your car for a few miles to see if the steering wheel continues to lock up or offers more freedom of movement.

Best Power Steering Stop Leak Value: Prestone AS262 Power Steering Fluid with Stop Leak

This power steering stop leak fluid works great at not only preventing leaks but also stopping them from happening while you drive. It’s made up of what the manufacturer refers to as high-grade oil and a multitude of additives to strengthen it for a guaranteed no-leak, smooth operation.

What we liked about this power steering stop leak is it works well in any temperature or climate; it won’t get clogged up in winter months or leave the power steering reservoir sticky in the hotter months. One of the best benefits of this compound is it corrodes rust and comes with an anti-foam agent so you don’t get that rush of foam coming back at you while filling the reservoir.

It is on the less expensive side when it comes to power steering stop leaks, and that’s not always a good thing. While it does a great job at filling leaks, it works best on smaller holes. So, if you want to fill larger leaks, you’ll want to invest in more of the product.

Best Power Steering Stop Leak Honorable Mention: Lucas Oil 10011 Power Steering Stop Leak

This solvent-free power steering leak stop may come in a smaller container, but it does a great job at stopping leaks. It combines with gas-extracted additives with special oils to fill holes and prevent loss of power steering fluid.

Another great feature of this power steering leak stop is it fights to prevent and reduce slack, squeals, and hard spots in worn rack and opinions. That gets rid of the annoying groan of your steering wheel and gives you a more pleasant time driving. The added components make it especially great for older cars since the high-quality additives break down rust and corrosion and fill leaks quickly.

While the saying “great things come in small packages” makes sense with this power steering leak stop, the size of this bottle is also a bit of a negative. It may only last a few weeks, leaving you to buy more bottles that are more expensive than other brands.

  • Wear gloves, a mask, and protective eyewear while using a power steering stop leak. If it touches your skin, it may be difficult to clean off. However, getting it in your eye could lead to irritation or worse symptoms.
  • To see if you’ve successfully stopped a leak, leave a piece of cardboard under the car where the power steering fluid usually leaks from. After filling the reservoir with stop leak, drive the car around for a bit, then park it over the cardboard. Check the cardboard to see if any leakage took place.
  • It’s best to check the best operating temperature for different power steering stop leak fluids. Some are designed for cold temperatures, while others work better in warmer climates.
  • Check to make sure the solution you get is designed for your specific car, as mentioned above. Not all power steering stop leak products are universal.


Q: Does this product act like normal power steering fluid?

A: While many are a mix of power steering fluid and stop leak fluid, not all will be combined together. It’s best to get a separate bottle of power steering solution to use after pouring in the stop leak fluid. 

Q: Can I pour the solution directly into the power steering reservoir?

A: Many products allow you to pour the liquid in without emptying the contents beforehand. However, there are some brands of power steering stop leak fluid that will have you empty the previous liquid before filling it with the new solution. Read the bottle carefully before applying.

Q: Is this a permanent fix to leaks?

A: While power steering stop leak fluids may seem like a permanent solution to a problem, they only last a short amount of time. To truly fix a leak for good, you will need to take the car to a mechanic to get a better understanding of the leak.
