Understanding BMW Power Steering Fluid

To properly maintain the power steering system in your BMW E90, it’s important to understand the different types of power steering fluid available and why using the right one is crucial.

Types Of Power Steering Fluid For BMW E90

It’s crucial to know which type of power steering fluid is suitable for your BMW E90 to ensure optimal performance and longevity of the steering system.

Several types of fluids are used in different power steering systems for various BMW models.

Here’s a breakdown of the most common types and the specific E90 models they are recommended for:

1. Pentosin CHF 11S: This synthetic hydraulic fluid is the manufacturer-recommended option for many BMW vehicles, including the BMW E90 328i N52 3.0L. It offers superior lubrication and protection under extreme temperatures and conditions.
2. Dexron 3 ATF: The E90s with N46 engines use this automatic transmission fluid (ATF) as their power steering oil. When using an ATF in your power steering system, it’s essential to ensure that it meets or exceeds the specifications of BMW.
3. CHF-L: For some pre-LCI (2005-2008) E90 models, there may be confusion over which power steering fluid to use due to variations in recommendations from different sources. However, it is best to consult your vehicle manual or a professional mechanic to determine the appropriate fluid type for these models.
4. Custom Formulations: In rare cases, speciality fluids may be suggested by enthusiasts or professionals based on unique driving conditions or requirements. Always research thoroughly and consult with an expert before using a custom formulation in your BMW E90’s power steering system.

Remember that using the correct power steering fluid plays a significant role in maintaining your vehicle’s performance and efficiency, so always choose wisely to avoid potential damage or costly repairs down the road.
