In order to help you find the best power steering fluid for your car we’ve researched and compared the leading OEM power steering fluid and aftermarket brands, checking out reviews and ranking formulas to bring you the top choices for Toyota, Honda, GM, Nissan and others. We looked at temperature range, viscosity, additives and whether each fluid was based on synthetic or mineral oils, since some power steering racks specifically call for one or the other. When you’re ready to upgrade your interior, read our best car accessories guide.
Our top pick, Honda’s OEM power steering fluid, is what Hondas came with from the factory and it’s specially formulated to provide superior wear protection and maintain that signature Honda steering feel.

Those who race or autocross Hondas typically change power steering fluid at least once a season, and even if you don’t put your car to particularly grueling use, a power steering fluid change can be a great way to rejuvenate the feel of a high mileage vehicle. Hondas often rack up a lot of miles, and filling up with fresh, OEM quality power steering fluid helps extend the life of components like bushings, seals and gaskets.
Award: Honorable Mention
WHY WE LIKE IT: Our pick for best aftermarket synthetic power steering fluid, Royal Purple MAX EZ can be mixed with conventional fluids and offers improved wear and corrosion protection to extend the life of any hydraulic power steering set up.

This Royal Purple power steering fluid is especially appealing for high-performance applications with hydraulic power steering racks. This advanced product uses a blend of select synthetic base oils plus Royal Purple’s proprietary Synerlec additive technology for improved performance, even in high temperatures. It ranks among the best power steering fluid types for many GM, Toyota, Mazda and Nissan vehicles. That takes care of your steering, but you might like the best portable air compressor for your tires.
Award: Best for Older Cars
WHY WE LIKE IT: This Prestone power steering fluid comes with a stop leak additive that revitalizes dried and old gaskets and seals, helping to extend the life of your steering rack.
Designed to help revitalize old gaskets and rack seals, this power steering fluid with stop leak is a great choice for most older domestic vehicles. For the money, it may be the best power steering fluid for Chevy and Chrysler models, especially those with hydraulic power steering racks. It can be used as an additive in older ZF hydraulic racks as well. This means it’s a good power steering fluid for BMW models made before about 2012 as well.
It’s less expensive than Royal Purple, and this Prestone power steering fluid has only a few notable drawbacks. One is that it’s not recommended for Honda or Acura, and it may not be ideal in Nissan and Hyundai steering racks either. Another is that it can take a while to see results if you’re looking to stop up leaks with it. Speaking of leaks, the best tire pressure gauge will tell you if you have one in your tires. Also, when it comes to power steering fluid Lucas makes some great products, like the Oil Power Steering Fluid which adds good quality lubricity to improve performance. Note that this is solely labeled at a power steering fluid and is not intended to be used in place of an automatic transmission fluid.
Award: Best Budget
WHY WE LIKE IT: Suitable for most GM, Ford and Chrysler vehicles, this Prestone power steering fluid is fortified with anti wear compounds and corrosion inhibitors to extend the life of your power steering rack.
A solid choice for power steering fluid changes in most domestic cars with hydraulic power steering, this Prestone power steering fluid costs significantly less than full synthetic fluids and yet helps extend the life of power steering pumps, rack and pinion seals and hoses. It also helps get rid of power steering whine and squeaks that you may get from dirty, old fluid.
While it’s not specifically formulated for high temperature use, and it doesn’t come with OEM approval for Japanese vehicles, it may still be the best power steering fluid for GM, Chrysler and some Ford cars and trucks. This Prestone power steering fluid includes anti-foaming agents that help prevent loss of assist during demanding driving. Red Line Power Steering Fluid also serves as one of the best steering oils, since it performs well and has greater resistance against heat and thermal breakdown. Also, when checking your power steering fluid level for your steering wheel, check the smell and color of the fluid as well to see how the fluid condition is and if it may need replacing. Tires are just as important for steering, so we recommend the best all season tires.
Award: Best Universal
WHY WE LIKE IT: This high quality universal fluid helps reduce noise and is a top recommended power steering fluid for Toyota, Lexus, Nissan, Mazda and Hyundai vehicles with hydraulic power steering.
A more affordable choice when doing a complete power steering fluid flush compared to Genuine Honda, this Idemitsu brand nonetheless provides nearly the same performance characteristics and is the recommended power steering fluid for Nissan Toyota, Lexus and many other Japanese and Korean brands.
Designed to reduce noise and ensure good lubrication even when cold, it can drastically cut down on squeaking and squawking from your rack and pinion, compared to old, dirty fluid. It also contains anti-wear chemicals to extend the life of the pump and gears. It promises excellent compatibility with seals and gaskets and offers anti-corrosive properties as well. If you want to use your vehicle for transport on your next ATV trip, you’ll want to take a look at the best ATV winch too. For more options, Ravenol makes great power steering fluid well-suited for hydraulic systems since its special formula is set to the highest hydraulic fluid standards. For example, the SSF Special Power Steering Fluid has excellent low viscosity flow characteristics to withstand low temperatures. Overall, without power steering fluid, the power steering pump may wear down or overheat without the lubricant and cause expensive damage to your car, so always make sure you and your vehicle are prepared.
In order to highlight the best power steering fluid choices for a wide range of cars and trucks, we first limited our search to include only those with proven anti-wear properties, meaning they had to at least promise compatibility with seals and gaskets, since improperly blended and dirty fluids can actually speed up wear and lead to steering rack seals drying out prematurely and cracking. Anti-corrosive properties were also considered a plus.
Next, we emphasized power steering fluids recommended by OEM automakers and reputable aftermarket providers. Enthusiast favorites, like the Royal Purple MAX (our #2 pick) were considered as well. Added high performance capability was considered a bonus.
Finally, we only included power steering fluid flush options that had the ability to mix with OEM power steering fluid. This way, if you need to top off your power steering system, you can use any of these safely without having to make sure to flush out all the original fluid.
