15 best power steering fluids
Content
All power steering fluids differ from each other, not only in color, but also in their characteristics: oil composition, density, viscosity, mechanical properties and other hydraulic parameters.
Therefore, if you are worried about the long and stable operation of the hydraulic power steering of a car, you need to follow the operating rules, change the slurry in the power steering in time and fill it with the best high-quality liquid. For the operation of the power steering pump two types of fluids are used - mineral or synthetic, in conjunction with additives that play a major role in the operation of the hydraulic booster.
It is quite difficult to determine the best fluid for power steering, because, according to the manufacturer's recommendation, it is better to pour the prescribed brand into a particular machine. And since far from all drivers comply with this requirement, we will try to compile a list of the 15 best power steering fluids that caused the most confidence and collected a lot of positive feedback.
Note that such liquids are poured into the power steering:
- conventional ATF, as in an automatic transmission;
- Dexron (II - VI), the same as ATP fluid, only a different set of additives;
- PSF (I — IV);
- Multi HF.
Therefore, the TOP of the best power steering fluids will consist of similar categories, respectively.
So, what is the best power steering fluid to choose from all those on the market?

Best Multi HF
Hydraulic oil The Multi HF motto. Multifunctional and high-tech synthetic green fluid for hydraulic systems. It was developed specifically for the latest generation of cars that are equipped with such systems as: power steering, hydraulic shock absorbers, hydraulic opening roof, etc. Reduces system noise, especially at low temperatures.

Pentosin CHF 11S. Dark green synthetic high quality hydraulic fluid used by BMW, Ford, Chrysler, GM, Porsche, Saab and Volvo. It can be poured not only into the hydraulic booster, but also into the air suspension, shock absorbers and other car systems that provide for the filling of such a liquid. Pentosin CHF 11S Central Hydraulic Fluid is suitable for use in vehicles under extreme conditions, as it has an excellent temperature-viscosity balance and can operate from -40°C to 130°C. A distinctive feature is not only the high price, but also a fairly high fluidity - viscosity indicators are about 6-18 mm² / s (at 100 and 40 degrees). For example, for its counterparts from other manufacturers according to the FEBI, SWAG, Ravenol standard, they are 7-35 mm² / s. A solid track record of approvals from leading auto manufacturers.
This PSF of a popular brand from the assembly line is used by German auto giants. Without fear for the power steering system, you can use it in any car, except for Japanese ones.

- - A good liquid, no chips are formed, but very aggressive to aluminum, plastic and seals.
- - After the replacement on my VOLVO S60, a smoother steering and quiet operation of the power steering immediately became noticeable. The howling sounds disappeared when the power steering was in extreme positions.
- - I decided to choose Pentosin, although our price is 900 rubles. per liter, but confidence in the car is more important ... On the street again -38, the flight is normal.
- - I live in Novosibirsk, in harsh winters the steering wheel spins like KRAZ, I had to try many different fluids, arranged a frosty test, took 8 popular brands with ATF, Dexron, PSF and CHF fluids. So the mineral Dextron became like plasticine, PSF was better, but Pentosin turned out to be the most liquid.

RAVENOL Hydraulic PSF Fluid — hydraulic fluid from Germany. Fully synthetic. Unlike most Multi or PSF fluids, it is the same color as ATF - red. It has a consistently high viscosity index and high oxidation stability. It is produced on the basis of hydrocracked base oil with the addition of polyalphaolefins with the addition of a special complex of additives and inhibitors. It is a special semi-synthetic fluid for power steering of modern cars. In addition to the hydraulic booster, it is used in all types of transmission (manual transmission, automatic transmission, gearbox and axles). According to the manufacturer's request, it has high thermal stability and is able to withstand low temperatures down to -40°C.
If it is not possible to buy original hydraulic fluid, this is a good choice for a Korean or Japanese car at a nice price.

- - I use ZIC in automatic transmission and power steering, and on various cars, brands TOYOTA, NISSAN. Even though it's cheap, it's enough for a couple of years. It showed itself well both in winter operating conditions and at high loads on the automatic transmission.
- - I filled it in at the beginning of summer, the pump worked without a hum in the heat, and the rail itself worked fine. At low temperatures, it also showed itself well, after warming up the internal combustion engine, the hydraulic booster worked perfectly, without hitches and wedging. When the budget is limited, then feel free to take this oil.
- — I’ve been driving for 5 years on a semi-blue ZIC Dexron III VHVI, there are no leaks, I never topped it up, replacing it every 2 years along with a tank.
- — After replacing the Subaru Impreza WRX car, the steering wheel became heavier.

- Pros:
- Ideal for cars with high mileage, because it is inexpensive and has a high viscosity.
- Good anti-wear properties.
- Cons:
- Too thick to be used as a power steering fluid in the northern regions.
- It is inconvenient that a liter canister is very difficult to find on sale, it is offered mainly only in 4 liters. canisters.
Since the design of the hydraulic booster contains parts made of various materials: steel, rubber, fluoroplastic - when choosing the right fluid, you need to look at the technical data and take into account the compatibility of the hydraulic oil with all these surfaces. it is also important to have additives that provide better friction between mating surfaces.
If you want to buy a really high-quality product, and not a fake, and complain that the liquid is bad, it is advisable to be interested in the availability of quality certificates for products.
Is it possible to mix power steering fluids with each other?
When topping up (and not completely replacing) fluid in the power steering reservoir, you need to follow a few simple rules:
- Mix mineral and synthetic liquid unacceptable!
- Green power steering fluid must not be stirred with liquids of other colors!
- stir mineral Dexron IID with Dexron III is possible, but subject to that the manufacturer in these two fluids uses identical additives.
- Mixing yellow hydraulic fluid with red, mineral type, permissible.
