Understanding What Mopar ATF+4 Power Steering Fluid Is
I found out that Mopar ATF+4 is a synthetic automatic transmission fluid that also serves as a power steering fluid and transfer case fluid in some vehicles.

Also, this fluid helps reduce wear, prevents foaming, and maintains smooth steering feel, which I noticed soon after changing the fluid.
Compatibility and Vehicle Requirements
Before buying, I made sure to check if Mopar ATF+4 was compatible with my car’s power steering system. It’s important because some vehicles require different fluids like Dexron or specialized synthetic oils.

Packaging and Quantity Considerations
