Yellow is the product for Mercedes vehicles. At least, they are most often used in the models of this brand.

There are also green liquids. These are also oils for power steering. They can also be synthetic and mineral. These products are very fond of European manufacturers. They cannot be used with automatic transmission.

What kind of oil to fill in the power steering

Motorists in reality and on the Internet love to argue about synthetic and mineral oils.
This is not very relevant here. So, in the power steering there are a lot of rubber parts. Synthetic hydraulic products perform much worse with rubber products that are made from natural rubbers, which is almost all rubber. A special rubber composition is intended for use.

On very rare cars, synthetic products are used for power steering. It is more correct to use only mineral products, if nothing is additionally written about this in the instructions.

Three simple rules that will make the power steering work flawlessly

Feel free to mix red and yellow mineral products. Green liquids should not be mixed with any others. Synthetics and mineral water also do not interfere. Therefore, if you are not entirely sure which oil to pour into the power steering, it will be useful to look at the instructions for the car.

If you look at the differences between automatic transmission products and power steering fluid, you can see a lot of interesting things. If we consider the functions of both tools, then in general their functions are the same. Both the one and the other oil are a working fluid that transmits pressure.
There is a difference - it consists in the composition and additives. But they can be perfectly used in power steering. On Japanese cars, you can find the same in the power steering as in the automatic transmission.

The Dextron family of products was created at the dawn of popularity for automatic transmissions.
Today, some call them transmission, although this is not entirely true. In fact it is called them ATF. This is an inexpensive power steering oil, its price is about 600 rubles per 1 liter.

Sly European manufacturers went far enough and banned anything to fill the power steering. You should only use what is recommended, and you only need to buy products in one place. This is a great way to make money.

If you are in doubt about which oil to pour into the power steering on a particular car, but want to purchase a good and non-original fluid, this will not affect the resource or performance. The only difference is the color. But you shouldn't mix them all the same. In some cases, this mixture frothy, which is not good.

And yet: what to pour into the power steering?

There are a lot of oils, there are also many manufacturers and brands. A high-quality liquid must be safe for people, and also work reliably at high temperatures.

Safety is what makes quality products different. When the liquid is heated, harmful vapors can be released, and since it is a chemical product, the vapors should not harm the driver or passengers. Usually a good quality liquid has a corresponding certificate. For example, Renault Logan power steering oil is completely safe for health.

An excellent, high-quality power steering fluid should calmly withstand temperatures above one hundred degrees without any changes. Bad oils can clog, which can be dire. In addition, with a sharp change in temperature conditions, the working fluid should not lose its original characteristics. It is very important.

So, we found out what kind of oil to fill in the power steering.
