Why Choose Specific Type of Fluid?

Basically GM 89021184 uses hydraulic fluids (not to be confused with ATF fluid). But if you will go for an alternative, I would suggest you go for the high-end synthetic ones. For example, Preston, AMSOIL or Pennzoil. Do not select synthetic fluids made out of base oils I or II.

Among the suggested ones, most people like using Preston PS fluid. But whatever you do, don’t mix different fluids. Chrysler Hybrid Manual strictly prohibits it.

But mostly you should remember the requirements for the PS fluid. It should be a perfect balance of viscosity, additives, detergents etc.

Why Are Synthetic Fluids Expensive?

Synthetic fluids like AMSOIL tend to be very expensive. It is natural to question the benefits of the oil being worth it or not.

Let’s talk about synthetic fluids first. As the name suggests, it is artificially made. They can be manufactured using petroleum components that have been chemically modified. There are alternative sources for deriving synthetic oils too!

A good synthetic oil demands expensive ingredients. And brands like AMSOIL, ensure that. You will notice it in the performance.

Most expensive synthetic oils offer extended drain intervals. They don’t damage the engine like so many cheap, ‘so called’ synthetic oils. Most cheap synthetic oils are made of Group I and II base oils. They provide protection every time, all days of the week!

But is it worth it?

Yes, because you will not need to change the oil as much. In other cases, you would need a change of oil almost as double as much you will need to change the synthetic oil.

So it all amounts to the same. Why would you miss the goodness of synthetic oil while counting the bucks that you will spend anyway,

Are Generic Fluids Compatible to GM 89021184 PS?

The most common type of generic fluid is the ATF (Automatic Transmission Fluid). It is a type of fluid that can be used in this particular GM part.

Try not to use any vegetable oils for the car, although some people use it.

What Happens if You Use Wrong Power Steering Fluid?

The first thing you will see is your seals getting damaged. Because the fluid attacks it.

The vehicle’s use of hydraulic or electro-hydraulic fluid is a piece of important information. You cannot use oils for a system differently designed than that oil. Otherwise, it will damage the system and the parts.

You will also face problems in steering, lubrication and overall performance of the car. The wrong steering fluid does not give enough protection from friction and corrosion. In fact, you need the correct fluid to keep the temperature of your power steering gear unit stable.

So incorrect fluid damaged the pumps by increasing friction or other reasons. Your car won’t last long and will bear premature corrosion.

How Often to Use the Steering Fluid?

You need to change the fluid every 75,000-100,000 miles. Usually that’s how it lasts. I would say, for GM 89021184, once you hit the 88,000-90,000 mark, change the fluid.

Final Words

Steering fluids maintain the health of your vehicle. It is very important for GM 89021184 as well. Therefore, choosing a high end and compatible fluid for your GM 89021184 is a must!
