I’d like to verify what I really can use without any issues. According to the manual, I have to use MB Power Steering Fluid or approved Dextron III ATF.

Can I mix MB Power Steering Fluid with Dextron III ATF ?
Are these fluids the same?
What does approved Dextron III ATF mean?
Is it any Dextron III ATF fluid or a specific brand?
How these fluids can be different if they are all Dextron III?

Thank you in advance!

Anyone can clarify which Steering fluid is acceptable to use and if it is ok to mix MB Power Steering Fluid with Dextron III ATF? Thank you.

why dont you just go to your local mb dealer and buy some mb ps fluid?

no guess work involved

I ended up doing that. However, I was not able to get a clear answer if I can mix both fluids. They do not know, at least my dealer. On the other hand, i don not know which fluid I have now in the car. This is why I'd like to know if it is OK to mix.

Well, There is a good chance that your truck has the stock mb fluid to begin with. The ps fluid is "for life" and removing the steering rack is usually a dealer only activity so they will refill it with stock fluid.

So the mixing question you have is most likely not an issue.

Thank you. I just added MB steering fluid. It should be fine.
