Which power steering fluid to choose?

Our vehicles are equipped with a range of systems and technological solutions that directly affect our comfort and safety on the road. Some of them are so common and obvious that we often don't even think about them. This group includes the power steering system, thanks to which it is so easy for us to maneuver the car. However, it must not be forgotten that good quality power steering fluid is required for it to function properly. How to choose the right one?

• Can different liquids be mixed together?
• At what intervals should the power steering fluid be changed?

Power steering fluid - why is it so important?

Power steering fluid, also known as power steering fluid, is the fluid component of the power steering system. It acts as an executive factor, therefore, lets us spin the wheels. Its main tasks also include lubricating and protecting the system from excessive heat and protecting the power steering pump from failure due to inaccurate operation (for example, excessive wheel slip in place). Therefore, his role is invaluable - it is a help system that gives us complete control over our car:

• we can immediately restore a straight track after a previously performed turning maneuver;
• while driving, we feel unevenness in the surface (the support system absorbs shocks) and we have information about the angle of rotation of the wheels.

The power steering fluid reservoir is located under the hood of the vehicle, above the power steering pump. We recognize him thanks to steering wheel symbol or sticker... The amount of liquid in the tank should be optimal (between minimum and maximum, preferably around MAXA). We can measure this with a dipstick that is part of the tank plug. When you need to make up for his lack, we need to know which power steering fluid to choose.

Types of support fluids

Classification of liquids by their composition

• Mineral fluids are petroleum based. This is the cheapest and easiest type of maintenance oil. In addition to the attractive price, they also act harmlessly on the rubber elements of the power steering. However, they have relatively short service life and prone to foaming... Most often used in older vehicles.
• Synthetic fluids - These are the most modern fluids used in power steering systems. They contain compositions of polyesters, polyhydric alcohols and a small amount of refined oil particles. Synthetics are more expensive than other types of liquids, but have excellent performance parameters: they are non-foaming, have a low viscosity and are extremely resistant to extreme temperatures.
• Semi-synthetic fluids They contain both mineral and synthetic substances. Their advantages include low viscosity and good lubricity. However, it should be borne in mind that they have a detrimental effect on the rubber elements of the power steering.
• Sealing liquids - with additives sealing power steering. They are used for small leaks to avoid costly repairs and replacements of the entire system.

Classification of liquids by color

• Power steering fluid, red - known as Dexron and manufactured to the standards of the General Motors group. It is used in Nissan, Mazda, Toyota, Kia, Hyundai and others, among others.
• Green power steering fluid - produced by the German company Pentosin. It is used in Volkswagen, BMW, Bentley, Ford and Volvo vehicles, as well as in Daimler AG vehicles.
• Yellow power steering fluid – mainly used in Mercedes-Benz vehicles. It is developed by the Daimler concern, and the production is carried out by persons who have the appropriate license.

When choosing a power steering fluid for our car, we need to look at the instructions for the car or service book... We can also find it by its VIN number. Remember that each manufacturer provides appropriate specifications and standards for the type of power steering fluid that must be strictly adhered to. Therefore, his choice cannot be accidental.

Can I mix different types of booster fluids? What liquid to top up?

The answer to the question of whether it is possible to mix different types of power steering fluid is unequivocal - no. Firmly it is not recommended to combine mineral, synthetic and semi-synthetic fluids. It should also be remembered that liquids of the same color can simultaneously have a completely different composition. For example, Dexron red fluids are available in both mineral and synthetic forms. Focusing only on their timbre is a big mistake. If we are not sure what fluid to add to the power steering, the best solution is to replace it completely.

How often should the power steering fluid be changed?

According to the general recommendations regarding the frequency of changing the power steering fluid, we should do this. on average, every 60-80 thousand km or every 2-3 years... More detailed information should be provided by the manufacturer himself. If they are not there or we cannot find them, then follow the above rule. Remember, it is best to change the fluid in a professional workshop.

Of course, regular fluid change intervals are not enough. To enjoy the flawless operation of the power steering, we will focus on a relaxed driving style and always buy good quality fluids, in accordance with the recommendations of the car manufacturer.
