Power steering is one of the key elements of a car, on which the comfort and ease of control depend. The service life of the pump, hoses, and rack directly depends on the type of lubricating fluid used in it. Many drivers wonder: what fluid to put in the power steering for a particular car model. In this material, we will take a detailed look at the types of fluids and give recommendations for popular cars.

What types of power steering fluids are there

Fluids for power steering are divided into three main groups:
  • Mineral — gently affect rubber seals, but lose their performance characteristics faster than others.
  • Semi-synthetic — the optimal balance between cost and operational stability.
  • Synthetic — designed for serious loads, but require precise compatibility with the system's materials.
Automakers use two fluid standards: ATF (Automatic Transmission Fluid) and specialized PSF (Power Steering Fluid). For this reason, there is no universal solution: always check the owner's manual before replacing.

Recommendations for specific models

Drivers often look for ready-made answers for their cars:
  • What fluid to put in the power steering of Golf 4 — as a rule, green fluid VW G 002 000 or an analogue, for example Pentosin CHF 11S, is used.
  • What fluid to put in the power steering of Opel Astra H — the factory recommends fluids like Dexron III (red tint).
  • What fluid to put in the power steering of Skoda Octavia Tour — green fluids such as VW G 002 000 or CHF 11S are used.
  • What fluid to put in the power steering of Opel Astra G — Dexron II or III is suitable, the choice depends on the year of manufacture.
  • What fluid to put in the power steering of Accent — most often ATF Dexron II or III is used.
  • What fluid to put in the power steering of Opel Vectra C — red fluid Dexron III or branded GM analogues are needed.
  • What fluid to put in the power steering of Toyota Camry 40 — the manufacturer prescribes ATF Dexron II or Toyota ATF Type T-IV.
  • What fluid to put in the power steering of Renault Logan — Elf Renaultmatic D3 SYN or similar ATF Dexron III is used.
As you can see, each car has its own specifics: somewhere a green fluid is used, and somewhere a red one. Mixing fluids of different types is strictly prohibited, otherwise there is a risk of damaging the pump.

Why the right choice is so important

Some car owners pour in the first fluid they come across. This is a gross mistake that can destroy the entire system. The power steering pump is sensitive to viscosity and chemical composition. If you use an unsuitable product, the following problems may occur:
  • Increased noise during operation.
  • Leaks due to damage to seals.
  • Jerks when turning the steering wheel.
  • Pump failure requiring expensive repairs.
Therefore, to the question «what fluid to put in the power steering» the correct answer is always the same: the one specified in the vehicle's documentation.

Fluid replacement procedure

The fluid should be renewed every 60–80 thousand kilometers, and also earlier if it has darkened and lost its transparency. The process looks like this:
  1. The old fluid is pumped out of the reservoir.
  2. If necessary, the system is flushed.
  3. Fresh fluid is poured in.
  4. Bleeding is performed — the steering wheel is turned several times from lock to lock.
This approach avoids air pockets and extends the life of the pump.

Summary

Now you know what fluid to put in the power steering of Golf 4, Opel Astra H, Skoda Octavia Tour, Opel Astra G, Accent, Opel Vectra C, Toyota Camry 40, and Renault Logan. Each model requires a strictly defined fluid, and there is no universal answer: some cars need green fluid, others need red ATF. Give preference to original products or proven analogues from well-known brands. Only in this case will the power steering work for a long time, providing easy and safe control.
