TOP 15 Power steering fluids (PSF, ATF, Dextron). Which ones are better

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 indicators.

Therefore, if you are concerned about the long and stable operation of your car’s hydraulic power steering, you need to follow the operating rules, change the fluid in the power steering on time and fill it with the best quality fluid. To operate the power steering pump, two types of fluids are used - mineral or synthetic, in combination with additives that play a major role in the operation of the hydraulic booster.

It is quite difficult to determine the best power steering fluid, because according to the manufacturer’s recommendation, it is better to pour the prescribed brand into a particular car. And since not all drivers comply with this requirement, we will try to compile a list of the 15 best power steering fluids that have inspired the most confidence and have collected many positive reviews.

Please note that the following fluids are poured into the power steering :

regular ATF, as in an automatic transmission;
Dexron (II - VI), the same as ATP liquid, 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, which power steering fluid is best to choose from all those on the market?

Category	Place	Name	Price
Best Multi Hydraulic Fluid	1	Motul Multi HF	from 1300 rub.
	2	Pentosin CHF 11S	from 1100 rub.
	3	Comma PSF MVCHF	from 1100 rub.

Reviews

— Not a bad liquid, no chips are formed, but it is very aggressive towards aluminum, plastic and seals.
— After the replacement on my VOLVO S60, a smoother steering motion and quieter power steering operation immediately became noticeable. The howling sounds when the power steering operates in extreme positions have disappeared.
— I decided to choose Pentosin, even though our price is 900 rubles. per liter, but confidence in the car is more important... It’s -38 outside again, the flight is normal.
— I live in Novosibirsk, in harsh winters the steering wheel turns like a KRAZ, I had to try a lot of different fluids, I did a frosty test, I took 8 popular brands with ATF, Dexron, PSF and CHF fluids. So mineral Dextron became like plasticine, PSF was better, but Pentosin turned out to be the most liquid.

— I live in the north, I drive a Cadillac SRX when -40 there were problems with the hydraulics, I tried to fill it with Zentralhydraulik-Oil, although there is no approval, but only a Ford, I took a risk, for the fourth winter I drive everything OK.
— I have a BMW, I used to fill it with the original Pentosin CHF 11S, and since last winter I switched to this fluid, the steering wheel turns much easier than with ATF.
— I drove 27 thousand km in my Opel in a year in a temperature range from -43 to +42°C. The power steering does not hum when starting, but in the summer it seemed that the fluid was a little thin because when turning the steering wheel in place, there was a feeling of friction between the shaft and the rubber.

— I use ZIC in automatic transmissions and power steering on various cars, brands TOYOTA, NISSAN. Although it’s budgetary, it’s enough for a couple of years. It performed well both in winter operating conditions and under high loads on the automatic transmission.
— I filled it up at the beginning of summer, the pump worked without a hum in the heat, and the rack itself worked great. It also performed well at low temperatures; after the engine warmed up, the hydraulic booster worked perfectly, without hesitations or jamming. When the budget is limited, then feel free to take this oil.
— I’ve been driving the semi-blue ZIC Dexron III VHVI for 5 years, there are no leaks, I’ve never topped it up, I replace it every 2 years along with the tank.
— After replacing it with a Subaru Impreza WRX, the steering wheel became heavier.

5

Pros:
Ideal for cars with high mileage, as it is inexpensive and has high viscosity.
Good anti-wear properties.

Minuses:
Too thick to be used as power steering fluid in northern regions.
It is inconvenient that a liter canister is very difficult to find on sale; it is mainly offered only in 4 liters. canisters.

Since the design of the hydraulic booster contains parts made of various materials: steel, rubber, fluoroplastic - when choosing a suitable 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.

In power steering, synthetic oils are used quite rarely (they are aggressive to rubber); synthetics are often poured into the automatic transmission of a car. Therefore, only fill the power steering system with mineral water, unless the instructions specifically indicate synthetic oil!

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 inquire about the availability of quality certificates for the products.

Application area

ATF Dextron was originally developed for automatic transmissions. Oil in an automatic transmission performs different functions: transmits torque, creates pressure on the clutches and guarantees proper friction, lubricates parts, protects against corrosion, and removes heat. When choosing ATP, you need to check the product for the Dextron specification.

Dextron specifications indicate the optimal viscosity index for each type of ATP. High viscosity oils increase the slippage of friction discs and increase wear on the rubbing parts of automatic transmissions. With low viscosity, the protective film on bearings and gears is thin and breaks quickly. Bullies appear. The seals are deformed. Automatic transmission fluid is leaking.

The operating viscosity of ATF Dexron III H is in the range of 7 - 7.5 cSt at 100℃. This indicator guarantees that Dextron 3 oil in automatic transmissions will last a long time without replacement, maintaining its performance properties.

ATF Dexron III H is used in 4 and 5-speed automatic transmissions manufactured before 2006. The boxes are installed in cars, commercial vehicles, and buses.

With the expansion of the functionality of the transmission fluid, the scope of application has also increased:

hydraulic systems: power steering, hydrostatic transmission, hydraulic drive, hydropneumatic suspension, hydraulic brake system;
