When people first started driving cars, they had to use a lot of manual force to get the steering wheel to turn. Due to modern technology, we no longer depend on brute strength to make a turn. However, things 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.
Why Trust Us
All of our reviews are based on market research, expert input, or practical experience with most products we include. This way, we offer genuine, accurate guides to help you find the best picks.
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 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.
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.
- 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 Reviews & Recommendations 2020
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 improves 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 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.
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 should invest in more of the product.
This solvent-free power steering leak stop comes in a small 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.
STP is a well-known manufacturer for car enthusiasts. Its power steering leak fluid repair helps ensure your steering wheel won’t lock up on you when you need it most. The fluid protects against everyday wear and tear and uses a two-in-one compound to get every seal in working order again. The liquid also revitalizes dried, hardened, and shrunken seals with its special formula conditioner. Another benefit of this particular fluid is it is completely compatible with other approved power steering fluids. You may also save some cash if you buy online rather than at the store. However, it may only be good enough to repair small leaks as opposed to larger ones. You may also end up needing multiple bottles as the container is on the small side.
Bar’s Leaks is another great brand that makes many things necessary to keep vehicles running smoothly and effectively. The fluid will help restore the performance of your vehicle so you can get back on the road more quickly. It also works to quiet down worn and noisy pumps so you don’t get that whining sound when you turn. The bottle also isn’t that bad looking either, as it isn’t a standard gray color. This helps it stand out on your shelf if you need to grab it quickly. It is made up of a dual action formula that conditions and prevents future leaks. Although it may improve your steering for a time, it won’t last forever. You will be using this bottle over and over again until you get more or inevitably have to take the car to the shop. It is also a higher-priced steering stop leak than other brands.
If you’re looking for a good high-quality power steering stop leak from Bar’s Leaks, consider the company's Grey model. While you will only get an 11-ounce bottle, the price is certainly worth it, as is the fluid. This power steering repair is reliable and effective on small leaks and even some larger ones. It stops and seals leaks, restores O-rings, and works with all other types of stop leak fluids. One bottle treats up to three quarts of fluid. However, it doesn’t work all that quickly. It may take a few applications or a few hours before you see any significant results. You may want to stock up, as the bottle is small and you may end up using a lot.
- 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.
