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.
Some kinds of power steering stop leak fluid are made solely to prevent or solve the problem of leaking fluid. However, others are more versatile — and a more versatile option can be even more helpful. If you opt for a steering stop leak solution that can be used for a number of different problems or situations, you’ll get more value out of every bottle. These formulas can cost a bit more, since they can be used for power steering leaks and other scenarios, but if you have an older car you’ll find it comes in handy often.
You may need a more highly concentrated or specialized formula depending on how severe the leak in your power steering system is. More severe leaks, or larger leaks, will require more stop leak fluid; they may also need a more powerful sealing compound to work. If your leak is pretty minor, on the other hand, you don’t need to worry much about the formulation and the strength.
The BlueDevil Power Steering Stop Leak 00232 fluid 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’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.
Prestone AS262 Power Steering Fluid with Stop Leak is a product that 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.
Lucas Oil 10011 Power Steering Stop Leak is a solvent-free solution — and though it comes in a smaller container, 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, and STP Power Steering Fluid & Stop Leak 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 2-in-1 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 Power Steering Repair 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 3 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.

It’ll give you everything you need to keep your steering rotating and operating smoothly on the road.
And this fluid is specially formulated to target — and combat — the biggest causes of power steering system breakdowns. It can stop leaks with ingredients that recondition hardened, shrinking seals in aging vehicles; it can also protect against pump breakdown. This formula will block out foam, wear and tear, and oxidation or corrosion. And it’s perfectly safe for use in most vehicles, able to operate in temperatures as high as 405 degrees or as low as -48 degrees.
There’s just one drawback: Valvoline’s dual-use fluid cannot be used in Honda or Acura vehicles.

This fluid swells, softens, and conditions.
There’s one more big benefit to this power steering fluid: it’s backed by a 100 percent money-back guarantee. If you aren’t thrilled with the results once it’s added into your power steering system, you can get your money back.
Johnsen's Power Steering Leak Sealer and Conditioner combines high-quality ingredients into a single fluid additive that’ll condition and soothe your power steering system. Designed to seal up any leaks and protect future leaks from springing up along the seals, O-rings, and gaskets, this single fluid can offer plenty of benefits. And it doesn’t cost you a ton, either.
This power steering stop leak product can be mixed with most factory power steering fluids. It’ll add conditioner and leak stop right into the flow of fluid, giving you a combination of protection and ongoing repairs. Sold in a 12-ounce bottle, you’ll get enough for one fill-up. As this fluid moves through the system it’ll keep seals soft and pliable, helping to ensure everything is tightly sealed — even as your vehicle sees a lot of wear and tear. Suitable for vehicles both old and new, just make sure to double-check that it’s a fit for your car’s factory fluid.
Here’s another two-in-one stop leak solution that can help you protect and maintain your vehicle: Armored Auto Group Power Steering and Stop Leak. Designed to work both as a basic power steering liquid and a stop leak additive, this specially formulated product offers help in multiple ways. It’s made to stop or reduce the amount of fluid you’re losing due to weak, leaking, and shrunken seals.
Add this power steering stop leak liquid into your vehicle, and it’ll prevent wear as it flows. It can even be used in place of regular power steering fluid, offering preventative maintenance as well as repairs where they’re needed. Each 12-ounce container revitalizes dried-out components, conditions for increased strength, and protects the pump from potential breakdown. It’s compatible with all approved power steering fluids too.
However, you’ll want to remember that this power steering stop leak can’t solve significant problems. If your power steering system has broken or scored seals, this additive can’t help — and shouldn’t be used.
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.
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.
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.
Technically, you’ll be able to continue driving your car while leaking power steering fluid for a while. However, as the fluid leaks out and isn’t replaced, the pump dries up — and that’s when your steering locks up, leaving you unable to move your vehicle without brute force. It’s better to take action as soon as you suspect a leak rather than wait. Waiting too long could leave you stranded or with costly repairs.
As long as you choose a power steering stop leak product that’s suitable for your car and its power steering system, it’s perfectly safe to use. Damage and potential problems only happen when you choose an incompatible product.
